Menu example

Menus are very commonly used element of Android which has been used in many types of applications. There are three types of menus in Android.

Options Menu.
Context Menu.
Popup Menu.

Options Menu:

Options menu is a primary menu of Android this menu is used in many applications. With the help of this menu the application will have a global impact in it like 'Settings', 'Logout', 'Search', 'Delete' etc. Menu will appear in the top of the action bar with three dots or it will appear in the default menu button of your android device. In Options menu there are two types again.

Without icons that appear in the form of list.
With icons which appears on the action bar horizontally.

The following steps will help us to make a Options Menu example.

We can create a new project or continue in existing one.
Under res directory create a new directory as menu.
Under menu directory create a new file "right click-->new-->Menu resource file" give a name for the file and hit OK.
In the menu file add items as following.

File: menu_main.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    
    <item
        android:id="@+id/search"
        android:title="Search" />

    <item
        android:id="@+id/settings"
        android:title="Settings" />

    <item
        android:id="@+id/logout"
        android:title="Logout" />

</menu>


Now go to MainActivity.java file and override two methods by pressing ctrl+o buttons. You will get the list of methods just select the following two methods from it.


OnCreateOptionsMenu = this method is used for inflating a menu directory and menu main xml file.
OnOptionsItemSelected = this method is used for on click event handling on the menu items.

File: MainActivity.java

package infinite.hss.com.menuexample;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    // for inflating the menu_main.xml    @Override    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return super.onCreateOptionsMenu(menu);
    }

    // for on click handling    @Override    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.search:
                Toast.makeText(this, "Clicked on " + item.getTitle(), Toast.LENGTH_SHORT).show();
                break;
            case R.id.settings:
                Toast.makeText(this, "Clicked on " + item.getTitle(), Toast.LENGTH_SHORT).show();
                break;
            case R.id.logout:
                Toast.makeText(this, "Clicked on " + item.getTitle(), Toast.LENGTH_SHORT).show();
                break;

        }
        return super.onOptionsItemSelected(item);
    }
}


Run the app and enjoy the options menu.

With Icons:

To add icons to the options menu you just need to add two extra attributes in menu_main.xml file as following.

File: menu_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/search"
        android:icon="@android:drawable/ic_menu_search"
        android:title="Search"
        app:showAsAction="always" />

    <item
        android:id="@+id/logout"
        android:icon="@android:drawable/ic_lock_power_off"
        android:title="Logout"
        app:showAsAction="always" />

    <item
        android:id="@+id/settings"
        android:title="Settings" />

</menu>


Run the app and enjoy options menu with icons.

Login with FaceBook example

noreply@blogger.com (Unknown) — Fri, 20 Jan 2017 07:24:00 +0000

In this example we learn how to login using facebook with a simple example along with getting User's name, Profile picture, Email Id, Birthday along with Gender.

Things we need to do:

Login to facebook for developers and create an App in it.
Integrate facebook SDK in to your App in android studio.
Code for your App.

You can login with your facebook credentials itself.

Create an App in facebook developers console. Give your own app name I have given my own app name as LoginAndroidStudio.

Create your app and you will get APP ID from facebook copy and paste it in your strings.xml file.

 <string name="fb_id">paste your add id here</string>

Now scroll down and click on add platform in your facebook developers page.

After clicking on the button you will get scrolled down. Fill the fields like your app's package and activity in which you are going to place fb login button and keyhash of your IDE.

Add this method in your activity and run the app to get your key hash.

package infinite.hss.com.loginandroidstudio;

import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.Signature;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Base64;
import android.util.Log;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;


public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        PrintHashKey();

    }

    public void PrintHashKey() {
        // Add this to print the key hash in log cat
        try {
            PackageInfo info = getPackageManager().getPackageInfo(
                    "infinite.hss.com.loginandroidstudio",
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.e("KEYHASH:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
        } catch (PackageManager.NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }
    }
}

Add this permissions and your app id in Manifest.xml

<uses-permission android:name="android.permission.INTERNET"/>

Add this meta data parameter in your Manifest.xml before activity parameter.

 <meta-data android:name="com.facebook.sdk.ApplicationId"

      android:value="@string/fb_id"/>


Now add this dependency in your build.gradle file.

compile 'com.facebook.android:facebook-android-sdk:4.0.0'

After adding all these details now run your app you will get keyhash in your log cat copy and paste it in your facebook developers page and click save.

After clicking save button one pop up will be shown to your click "Use this package name".

Now setup for your app in facebook is done, all you need to do now is code in Android Studio.

Before coding the project copy and paste this dependency into build.gradle.

compile 'com.squareup.picasso:picasso:2.5.2'

Picasso library is used to show image's and image url's into imageView.

Now copy and paste the following xml code into your activity_main.xml file.

File: activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>

        android:textStyle="bold" />


    <com.facebook.login.widget.LoginButton
        android:id="@+id/login_buttonFB"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_margin="30dp" />

    <Button
        android:id="@+id/btn_logOut"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="30dp"
        android:layout_marginRight="30dp"
        android:background="@color/colorPrimary"
        android:text="Logout"

Phone Call example selecting Contacts from phone

In this tutorial we will learn how to call by selecting contacts from mobile with a simple example using Android Studio. In previous example we learn how to make a call just by giving hard coded number.

Example:

Create a new project in Android Studio and name it as PhoneCall.
Copy and paste the following code in activity_main.xml.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    android:padding="10dp"
    tools:context="hss_24.example.com.phonecall.MainActivity">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="40dp"
        android:gravity="center_horizontal"
        android:text="Android Lovers"
        android:textSize="20dp"
        android:textStyle="bold" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="1">

        <TextView
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.8"
            android:gravity="center"
            android:text="Select Contact from list"
            android:textSize="18dp"
            android:textStyle="bold" />

        <ImageButton
            android:id="@+id/btn_contacts"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.2"
            android:src="@android:drawable/stat_sys_phone_call" />

    </LinearLayout>


</LinearLayout>


Copy and paste the following code in MainActivity.java.

File: MainActivity.java:

import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.provider.ContactsContract;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageButton;

public class MainActivity extends AppCompatActivity {
    ImageButton contacts;
    private static final int CONTACT_PICKER_RESULT = 1001;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        contacts = (ImageButton) findViewById(R.id.btn_contacts);

        contacts.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent pickContactIntent = new Intent(Intent.ACTION_PICK, Uri.parse("content://contacts"));
                pickContactIntent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE); // Show user only contacts w/ phone numbers
                startActivityForResult(pickContactIntent, CONTACT_PICKER_RESULT);
            }
        });


    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // Check which request it is that we're responding to
        if (requestCode == CONTACT_PICKER_RESULT) {
            // Make sure the request was successful
            if (resultCode == RESULT_OK) {
                // Get the URI that points to the selected contact
                Uri contactUri = data.getData();
                // We only need the NUMBER column, because there will be only one row in the result
                String[] projection = {ContactsContract.CommonDataKinds.Phone.NUMBER};

                Cursor cursor = getContentResolver()
                        .query(contactUri, projection, null, null, null);
                cursor.moveToFirst();

                // Retrieve the phone number from the NUMBER column
                int column = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
                String number = cursor.getString(column);

                // set intent and call
                Intent callIntent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + number));
                startActivity(callIntent);

            }
        }
    }

}


Give the following permission in the Manifest file to read the phone contacts.

File: AndroidMainfest.xml: 

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.nouman.phonecall">

    <uses-permission android:name="android.permission.READ_CONTACTS" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

Phone Call Example in Android

In this tutorial we will learn how to implement phone call in an Android app with the help of Intent in Android Studio. We will hard code a number and while we press a call button in this example. In the next tutorial we will call from selecting from contacts list.

Example:

Create a new project in Android Studio and name it as PhoneCall.
In a activity_main.xml paste the following code.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    android:padding="10dp"
    tools:context="hss_24.example.com.phonecall.MainActivity">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="40dp"
        android:gravity="center_horizontal"
        android:text="Android Lovers"
        android:textSize="20dp"
        android:textStyle="bold" />

    <Button
        android:id="@+id/btn_call"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Call" />

</LinearLayout>

Now paste the following code in MainActivity.java. Here we are calling a hard coded number with the help of ACTON_DIAL.

File: MainActivity.java:

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    Button call;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        call = (Button) findViewById(R.id.btn_call);
        call.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // set intent and call
                Intent intent = new Intent(Intent.ACTION_DIAL);
                intent.setData(Uri.parse("tel:1212121212"));
                startActivity(intent);
            }
        });

    }
}

Now run the App and enjoy the output.

noreply@blogger.com (Unknown) — Thu, 21 Jul 2016 13:53:00 +0000

Show or hide a widget in ListView

In this tutorial we will learn how to show or hide a widget in listview when checkbox is checked or unchecked with a simple example in Android Studio.

In this example we will have a TextView, CheckBox and Spinner in a listview cell. When checkbox is checked the spinner will disable and when it is unchecked the spinner will enable.

Example:

Create a new project in Android Studio and name it as ListView.
In activity main.xml copy and paste the following code.

File: activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <ListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        
    </ListView>

</RelativeLayout>

</RelativeLayout>

Create a new xml file in layout directory and name it as my_cell for listview cell.
Copy and paste the following code in my_cell.xml file.

File: my_cell.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="80dp"
    android:gravity="center"
    android:orientation="horizontal"
    android:weightSum="2">

    <TextView
        android:id="@+id/textView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:textStyle="bold"
        android:textColor="@color/colorAccent"
        android:text="TextView" />

    <CheckBox
        android:id="@+id/checkbox"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.6"
        android:text="Check" />

    <Spinner
        android:id="@+id/spinner"
        android:layout_width="0dp"
        android:layout_height="50dp"
        android:layout_weight="0.4">

    </Spinner>

</LinearLayout>

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/ic_notification"
        android:drawable="@drawable/bell"
        android:gravity="center" />

    <!-- set a place holder Drawable so android:drawable isn't null -->
    <item
        android:id="@+id/ic_badge"
        android:drawable="@drawable/bell" />
</layer-list>



Now its time to code. Create a new java class and name it as BadgeDrawable.
Copy paste the following code in BadgeDrawable.java.

File: BadgeDrawable.java:

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.ColorFilter;
import android.graphics.Paint;
import android.graphics.PixelFormat;
import android.graphics.Rect;
import android.graphics.Typeface;
import android.graphics.drawable.Drawable;


public class BadgeDrawable extends Drawable {

    private float mTextSize;
    private Paint mBadgePaint;
    private Paint mTextPaint;
    private Rect mTxtRect = new Rect();

    private String mCount = "";
    private boolean mWillDraw = false;

    public BadgeDrawable(Context context) {
        mTextSize = context.getResources().getDimension(R.dimen.badge_text_size);

        mBadgePaint = new Paint();
        mBadgePaint.setColor(Color.RED);
        mBadgePaint.setAntiAlias(true);
        mBadgePaint.setStyle(Paint.Style.FILL);

        mTextPaint = new Paint();
        mTextPaint.setColor(Color.WHITE);
        mTextPaint.setTypeface(Typeface.DEFAULT_BOLD);
        mTextPaint.setTextSize(mTextSize);
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextAlign(Paint.Align.CENTER);
    }

    @Override
    public void draw(Canvas canvas) {
        if (!mWillDraw) {
            return;
        }

        Rect bounds = getBounds();
        float width = bounds.right - bounds.left;
        float height = bounds.bottom - bounds.top;

        // Position the badge in the top-right quadrant of the icon.
        float radius = ((Math.min(width, height) / 2) - 1) / 2;
        float centerX = width - radius - 1;
        float centerY = radius + 1;

        // Draw badge circle.
        canvas.drawCircle(centerX, centerY, radius, mBadgePaint);

        // Draw badge count text inside the circle.
        mTextPaint.getTextBounds(mCount, 0, mCount.length(), mTxtRect);
        float textHeight = mTxtRect.bottom - mTxtRect.top;
        float textY = centerY + (textHeight / 2f);
        canvas.drawText(mCount, centerX, textY, mTextPaint);
    }

    /*
    Sets the count (i.e notifications) to display.
     */
    public void setCount(int count) {
        mCount = Integer.toString(count);

        // Only draw a badge if there are notifications.
        mWillDraw = count > 0;
        invalidateSelf();
    }

    @Override
    public void setAlpha(int alpha) {
        // do nothing
    }

    @Override
    public void setColorFilter(ColorFilter cf) {
        // do nothing
    }

    @Override
    public int getOpacity() {
        return PixelFormat.UNKNOWN;
    }
}



Create a new java class and name it as Utils.
Copy paste the following code in Utils.java.

File: Utils.java:

import android.content.Context;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.LayerDrawable;

public class Utils {
    public static void setBadgeCount(Context context, LayerDrawable icon, int count) {

        BadgeDrawable badge;

        // Reuse drawable if possible
        Drawable reuse = icon.findDrawableByLayerId(R.id.ic_badge);
        if (reuse != null && reuse instanceof BadgeDrawable) {
            badge = (BadgeDrawable) reuse;
        } else {
            badge = new BadgeDrawable(context);
        }

        badge.setCount(count);
        icon.mutate();
        icon.setDrawableByLayerId(R.id.ic_badge, badge);
    }
}



Now copy paste the following code in MainActivity.java.

File: MainActivity.java:

import android.graphics.drawable.LayerDrawable;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends AppCompatActivity {
    private int mNotificationsCount = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new FetchCountTask().execute();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_home, menu);

        // Get the notifications MenuItem and
        // its LayerDrawable (layer-list)
        MenuItem item = menu.findItem(R.id.action_notifications);
        LayerDrawable icon = (LayerDrawable) item.getIcon();

        // Update LayerDrawable's BadgeDrawable
        Utils.setBadgeCount(this, icon, mNotificationsCount);

        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == R.id.action_notifications) {
            // TODO: display unread notifications.
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    /*
    Updates the count of notifications in the ActionBar.
     */
    private void updateNotificationsBadge(int count) {
        mNotificationsCount = count;

        // force the ActionBar to relayout its MenuItems.
        // onCreateOptionsMenu(Menu) will be called again.
        invalidateOptionsMenu();
    }

    /*
    Sample AsyncTask to fetch the notifications count
    */
    class FetchCountTask extends AsyncTask<Void, Void, Integer> {

        @Override
        protected Integer doInBackground(Void... params) {
            // example count. This is where you'd
            // query your data store for the actual count.
            return 5;
        }

        @Override
        public void onPostExecute(Integer count) {
            updateNotificationsBadge(count);
        }
    }
}

WebView example in Android

noreply@blogger.com (Unknown) — Mon, 20 Jun 2016 10:07:00 +0000

WebView in Android

In this tutorial we will learn to implement the WebView in Android Studio with a simple example.

WebView in Android is used to display web pages in your Android Application.

Example:

Create a new project in Android Studio and name it as WebView and copy paste or do the following things that we describe as follows.
Add a WebView element in your main xml activity.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="hss_24.example.com.webview.MainActivity">

   <WebView
       android:id="@+id/webView"
       android:layout_width="match_parent"
       android:layout_height="match_parent">
   </WebView>

</LinearLayout>


Initialize the WebView in a java file and do the following code.

File: MainActivity.java:

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // initialize webView and set url
        WebView webView = (WebView)findViewById(R.id.webView);
        webView.loadUrl("http://androidloversnbaig.blogspot.in/");

        // enabling javaScript
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);
    }
}


Add internet setting in your Manifest file.

Manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="hss_24.example.com.webview">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>


Add internet setting in your Manifest file.
Tats it!!!... Now run the application and enjoy the Webview.

Create a new java class as DataBaseHelper which is used to handle all the database functions.

File: DataBaseHelper.java:

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DatabaseHelper extends SQLiteOpenHelper {

    //    database name and version
    public static String DATABASE_NAME = "sample.db";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, 1);
    }

    //    create database table and columns
    @Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL("create TABLE IF NOT EXISTS College" + "(id integer primary key,name text,roll_no text,college text,course text)");

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    }

    //    insert the data into database columns
    public void insertRow(String name, String roll_no, String college, String course) {
        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues cn = new ContentValues();

        cn.put("name", name);
        cn.put("roll_no", roll_no);
        cn.put("college", college);
        cn.put("course", course);
        db.insert("College", null, cn);
    }

    //    get the data from database
    public Cursor get() {
        SQLiteDatabase db = this.getReadableDatabase();

        String str = "select * from College";
        Cursor cursor = db.rawQuery(str, null);
        cursor.moveToFirst();
        return cursor;
    }
}



Do the following code in main java file to save data into database.

File: MainActivity.java:
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {
    EditText name, rool_number, college, course;
    Button save, retrive;
    String name_str, roolNo_str, college_str, course_str;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final DatabaseHelper db = new DatabaseHelper(this);

        name = (EditText) findViewById(R.id.edit);
        rool_number = (EditText) findViewById(R.id.edit2);
        college = (EditText) findViewById(R.id.edit3);
        course = (EditText) findViewById(R.id.edit4);

        save = (Button) findViewById(R.id.btn);
        retrive = (Button) findViewById(R.id.btn2);

        // get the data from edittext store into strings and then save into database
        save.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                name_str = name.getText().toString();
                roolNo_str = rool_number.getText().toString();
                college_str = college.getText().toString();
                course_str = course.getText().toString();

                db.insertRow(name_str, roolNo_str, college_str, course_str);
                Toast.makeText(getApplicationContext(), "Saved", Toast.LENGTH_SHORT).show();
                name.setText("");
                rool_number.setText("");
                college.setText("");
                course.setText("");
                db.close();

            }
        });

        retrive.setOnClickListener(new View.OnClickListener() {

noreply@blogger.com (Unknown) — Thu, 31 Mar 2016 13:50:00 +0000

Shared Preferences In Android

Shared Preferences in Android is used to store or save small amount of data into an Android Application in the form of key and value pair.

Example:

In this tutorial we will learn to save data in to Android Shared Preferences with an example.

Create a new project Sharedpreference in Android Studio.
Design the main layout as follows.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="hss_24.sharedpreference.MainActivity">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="40dp"
        android:gravity="center"
        android:text="Android Lovers"
        android:textColor="@color/colorPrimary"
        android:textSize="28sp"
        android:textStyle="bold" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="40dp"
        android:gravity="center"
        android:text="Shared Preferences"
        android:textColor="@color/colorPrimary"
        android:textSize="28sp"
        android:textStyle="bold" />

    <EditText
        android:id="@+id/email_edit"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="20dp"
        android:hint="Enter email" />

    <EditText
        android:id="@+id/password_edit"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter password" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="20dp"
        android:gravity="center">

        <Button
            android:id="@+id/save"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginRight="20dp"
            android:text="Save" />

        <Button
            android:id="@+id/login"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="20dp"
            android:text="Show" />

    </LinearLayout>

</LinearLayout>


Modify the main java file as follows.

File: MainActivity.java:

import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button login = (Button) findViewById(R.id.login);
        Button save = (Button) findViewById(R.id.save);

        final EditText email = (EditText) findViewById(R.id.email_edit);
        final EditText password = (EditText) findViewById(R.id.password_edit);

        save.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String email_str = email.getText().toString();
                String pass_str = password.getText().toString();
                SharedPreferences sharedPreferences = getSharedPreferences("preferences", Context.MODE_PRIVATE);
                SharedPreferences.Editor editor = sharedPreferences.edit();
                editor.putString("email", email_str);
                editor.putString("password", pass_str);
                editor.commit();
                Toast.makeText(getApplicationContext(), "Saved", Toast.LENGTH_SHORT).show();
            }
        });

        login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                SharedPreferences sharedPreferences = getSharedPreferences("preferences", Context.MODE_PRIVATE);
                String str = null;
                String str2 = null;
                if (sharedPreferences.contains("email")) {
                    str = sharedPreferences.getString("email", "");

                }

                if (sharedPreferences.contains("password")) {
                    str2 = sharedPreferences.getString("password", "");

                }

                Toast.makeText(getApplicationContext(), "" + str + "\n" + "" + str2, Toast.LENGTH_LONG).show();
            }
        });
    }
}


Here we are storing the editText data into string and saving the string in shared preferences on click of save button and showing that data in Toast on click of show button.
Run the App and enjoy the output.

ProgressBar Dialog In Android

noreply@blogger.com (Unknown) — Thu, 10 Mar 2016 12:53:00 +0000

ProgressBar Dialog Example In Android

In this tutorial we will learn to implement progress dialog's for spinner progress bar and horizontal progress bar in Android.

We will learn here two types of Progress bar's, Horizontal and Spinner. We use horizontal for downloading and spinner for loading.

Example:

Create a new project and name it as ProgressBar in Android Studio.
Design the main layout file as follows.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.hss_24.progressbar.MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:text="ANDROID LOVERS"
        android:textSize="28sp"
        android:textStyle="bold" />


    <Button
        android:id="@+id/btn_spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="80dp"
        android:text="Spinner ProgressBar" />

    <Button
        android:id="@+id/btn_horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Horizontal ProgressBar" />

</LinearLayout>


Write the code in the main java file as follows.

File: MainActivity.java:

import android.app.ProgressDialog;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button button_spinner = (Button) findViewById(R.id.btn_spinner);
        Button button_horizontal = (Button) findViewById(R.id.btn_horizontal);

        button_spinner.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                ProgressDialog progress_spinner = new ProgressDialog(MainActivity.this);
                progress_spinner.setMessage("Loading...");
                progress_spinner.setProgressStyle(ProgressDialog.STYLE_SPINNER);
                progress_spinner.show();

            }
        });

        button_horizontal.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                ProgressDialog progress_horizontal = new ProgressDialog(MainActivity.this);
                progress_horizontal.setMessage("Downloading...");
                progress_horizontal.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
                progress_horizontal.setIndeterminate(true);
                progress_horizontal.show();
            }
        });

    }
}

Design the main layout as follows.
No need to code anything just run the Application.

File: MainActivity.java:

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

Notification In Android

noreply@blogger.com (Unknown) — Tue, 08 Mar 2016 11:53:00 +0000

Notification In Android Example

In this tutorial we will learn how to implement Android push notification with a simple example.

A notification is a message that you can display the user outside the Application. In this example we will show a notification and on click of the notification we will launch another activity.

Example:

Create a new project in Android Studio and name it as Notification.
Create a new Activity and name it as Main2Activity.
Design a new Button in main layout as follows.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <Button
        android:id="@+id/button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:onClick="createNotification"
        android:text="Create Notification" >

    </Button>

</LinearLayout>


Do the following code in Main java file as follows.

File: MainActivity.java:

import android.annotation.TargetApi;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    @TargetApi(Build.VERSION_CODES.JELLY_BEAN)
    public void createNotification(View view) {
        // Prepare intent which is triggered if the notification is selected
        Intent intent = new Intent(this, Main2Activity.class);
        PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);

        // Build notification
        Notification noti = new Notification.Builder(this)
                .setContentTitle("Notification from " + "androidlovers@gmail.com")
                .setContentText("AndroidLovers").setSmallIcon(R.drawable.bell)
                .setContentIntent(pIntent)
                .addAction(R.drawable.phone, "Call", pIntent)
                .addAction(R.drawable.more, "More", pIntent)
                .addAction(R.drawable.info, "Info", pIntent).build();
        NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        // hide the notification after it is selected
        noti.flags |= Notification.FLAG_AUTO_CANCEL;
        notificationManager.notify(0, noti);

    }
}


Do the following things in Main2Activity files.

File: activity_main2:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="match_parent" >

    <TextView
        android:text="ANDROID LOVERS"
        android:layout_gravity="center"
        android:layout_marginTop="30dp"
        android:textSize="24sp"
        android:textStyle="bold"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:layout_gravity="center"
        android:layout_marginTop="100dp"
        android:text="Welcome to Android lovers" >
    </TextView>

</LinearLayout>

File: Main2Activity.java:
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class Main2Activity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
    }
}



Run the App and enjoy the notification.

Animation In Android

noreply@blogger.com (Unknown) — Mon, 07 Mar 2016 11:45:00 +0000

Animation In Android Example

In this tutorial we will learn to implement the Android Animation with a simple example in Android Studio.

There are two types of animations in Android:

Tween Animation.

Creates an animation with a series of transformation with a single image

Frame Animation.
Creates an animation with the sequence of images.

Example:

Create a new project as AnimationInAndroid in Android Studio.
Create a new directory(folder) in res and name it as anim.
Create the following animation xml's in anim folder, these xml's are for tween animation.

File: bounce.xml:

In this xml, if we click on the image the image will bounce from the upwards.

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Bounce animation-->
    <scale
        android:duration="500"
        android:fromXScale="1.0"
        android:fromYScale="0.0"
        android:toXScale="1.0"
        android:toYScale="1.0" />
</set>

File: move.xml:


In this xml, if we click on the image the image will move from right to left.

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Move animation-->
    <translate
        android:fromXDelta="0%p"
        android:toXDelta="75%p"
        android:duration="1000" />

</set>

File: rotate.xml:


In this xml, if we click on the image the image will rotate.

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Rotate animation-->
    <rotate android:fromDegrees="0"
        android:toDegrees="360"
        android:pivotX="50%"
        android:pivotY="50%"
        android:duration="10000"
        android:repeatMode="restart"
        android:repeatCount="infinite" />

</set>

File: scale.xml:

In this xml, if we click on the image the image will scale.


<set xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Scale animation-->
    <alpha
        android:duration="10000"
        android:fromAlpha="0.0"
        android:toAlpha="1.0" />
</set>

File: zoom.xml:

In this xml, if we click on the image the image will zoom in.


<set xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Zoom animation-->
    <scale
        android:duration="1000"
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="3"
        android:toYScale="3" >
    </scale>

</set>


In main layout do the following design.

File: activity_main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context="com.example.hss_24.animationinandroid.MainActivity">

    <TextView
        android:gravity="center_horizontal"
        android:text="ANDROID LOVERS"
        android:textSize="22sp"
        android:textStyle="bold"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <TextView
        android:gravity="center_horizontal"
        android:text="This is Tween Animation"
        android:textSize="22sp"
        android:textStyle="bold"
        android:layout_marginTop="30dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <ImageView
        android:layout_marginTop="10dp"
        android:id="@+id/img_tween"
        android:src="@drawable/ic_launcher"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <Button
        android:id="@+id/frame"
        android:layout_marginTop="60dp"
        android:text="click to show frame animation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />


</LinearLayout>



Do the code for tween animation in main java file as follows.

File: MainActivity.java
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    public int clickcount=1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final ImageView img=(ImageView)findViewById(R.id.img_tween);
        Button btn_frame=(Button)findViewById(R.id.frame);

        //   tween animation imageview
        img.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //   click count for imageview
                if (clickcount == 1) {
                    //   loading animation and setting it in imageview
                    Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.zoom);
                    img.startAnimation(animation);
                    Toast.makeText(MainActivity.this, "Zoom", Toast.LENGTH_SHORT).show();
                } else if (clickcount == 2) {
                    Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.scale);
                    img.startAnimation(animation);
                    Toast.makeText(MainActivity.this, "scale", Toast.LENGTH_SHORT).show();
                } else if (clickcount == 3) {
                    Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.rotate);
                    img.startAnimation(animation);
                    Toast.makeText(MainActivity.this, "Rotate", Toast.LENGTH_SHORT).show();
                } else if (clickcount == 4) {
                    Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.move);
                    img.startAnimation(animation);
                    Toast.makeText(MainActivity.this, "Move", Toast.LENGTH_SHORT).show();
                } else if (clickcount == 5) {
                    Animation animation = AnimationUtils.loadAnimation(getApplication(), R.anim.bounce);
                    img.startAnimation(animation);
                    Toast.makeText(MainActivity.this, "bounce", Toast.LENGTH_LONG).show();
                }

                if (clickcount == 5) {
                    clickcount = 1;
                } else {
                    clickcount++;
                }

            }
        });
        btn_frame.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(MainActivity.this, Frame.class);
                startActivity(i);
            }
        });

    }

}



Create a new Activity for frame animation and name it as Frame.
Do the following design in frame layout, as follows

File: activity_frame.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.hss_24.animationinandroid.Frame">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:text="ANDROID LOVERS"
        android:textSize="22sp"
        android:textStyle="bold" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp"
        android:gravity="center_horizontal"
        android:text="This is Frame Animation"
        android:textSize="22sp"
        android:textStyle="bold" />

    <ImageView
        android:id="@+id/img_frame"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp" />

</LinearLayout>


Download the following images and paste it in the drawable folder.

   Images.zip

Create a new drawable xml, right click on drawable folder -> New -> Drawable resource file and name it as frame.
After creating the frame.xml set the images that you have in your drawable folder and set the duration.

File: frame.xml:
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/frame0a" android:duration="50"/>
    <item android:drawable="@drawable/frame1a" android:duration="50"/>
    <item android:drawable="@drawable/frame2a" android:duration="50"/>
    <item android:drawable="@drawable/frame3a" android:duration="50"/>
    <item android:drawable="@drawable/frame4a" android:duration="50"/>
    <item android:drawable="@drawable/frame5a" android:duration="50"/>
    <item android:drawable="@drawable/frame6a" android:duration="50"/>
    <item android:drawable="@drawable/frame7a" android:duration="50"/>
    <item android:drawable="@drawable/frame8a" android:duration="50"/>
    <item android:drawable="@drawable/frame9a" android:duration="50"/>
    <item android:drawable="@drawable/frame10a" android:duration="50"/>
    <item android:drawable="@drawable/frame11a" android:duration="50"/>
    <item android:drawable="@drawable/frame12a" android:duration="50"/>

</animation-list>


Do the following code in Frame.java file, as follows.

File: Frame.java:
import android.graphics.drawable.AnimationDrawable;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;

public class Frame extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_frame);

        //   frame animation imageview
        final ImageView frame = (ImageView) findViewById(R.id.img_frame);
        //  set frame drawable to imageview
        frame.setBackgroundResource(R.drawable.frame);

        //   start frame animatio
        ((AnimationDrawable) frame.getBackground()).start();

        frame.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //   activate animation if it is not activated
                frame.setActivated(!frame.isActivated());
            }
        });
    }
}



Run the Application and enjoy the animation..

Fragments Example in Android

noreply@blogger.com (Unknown) — Fri, 04 Mar 2016 12:57:00 +0000

Fragments example in Android

In this tutorial we will learn to implement the Fragments with a simple example in Android Studio.

Fragment is a known as a sub activity which we can reuse in different activities as well. Fragments are also a smart way of developing in Android because of its very fast and flexible way of interaction.

Example:

Create a new project as Fragments in Android Studio.
Create two fragment layout's and two fragment Classes in the project.

File: fragment_one.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#098"
    android:orientation="vertical">

    <TextView
        android:text="Fragment One"
        android:gravity="center"
        android:textSize="28sp"
        android:textStyle="bold"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

File: fragment_two.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#088"
    android:orientation="vertical">

    <TextView
        android:text="Fragment Two"
        android:gravity="center"
        android:textSize="28sp"
        android:textStyle="bold"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>


When we create the fragment class we have to extend the Fragment in it and we have to inflate the layout of the fragment.

File: FragmentOne.java:

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;


public class FragmentOne extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//        inflate fragment layout
        return inflater.inflate(R.layout.fragment_one,container,false);
    }
}

File: FragmentTwo.java:
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;


public class FragmentTwo extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        //        inflate fragment layout
        return inflater.inflate(R.layout.fragment_two,container,false);
    }
}


Design a main layout with two buttons as fragment one and fragment two.
Give the main layout id as replace_fragment to its main layout.

File: activity_main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/fragment_replace"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.hss_24.fragments.MainActivity">

    <LinearLayout
        android:id="@+id/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="horizontal">

        <Button
            android:id="@+id/btn_one"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="fragment one" />

        <Button
            android:id="@+id/btn_two"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="fragment two" />

    </LinearLayout>


</LinearLayout>



Do the following code in main java file as follows.
Here if we click button_one fragment_one gets replaced and if we click button_two fragment_two gets replaced.

File: MainActivity.java:
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btn_one = (Button) findViewById(R.id.btn_one);

        btn_one.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //   replace fragment_one
                Fragment fragment_one = new FragmentOne();
                FragmentManager fragmentManager = getFragmentManager();
                FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                fragmentTransaction.replace(R.id.fragment_replace, fragment_one);
                fragmentTransaction.commit();
            }
        });

        Button btn_two = (Button) findViewById(R.id.btn_two);

        btn_two.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //   replace fragment_two
                Fragment fragment_two = new FragmentTwo();

How to change fonts in Android

noreply@blogger.com (Unknown) — Thu, 03 Mar 2016 13:30:00 +0000

Custom Font's Example In Android

In this tutorial we will learn how to change the fonts with a simple example in Android Studio.

In this example we will implement four types of fonts that we will show in the textview's.

Example:

Create a new project as Font.
Design four TextView's in main layout.
Create an assets folder under res folder, right click res -> New -> Folder -> and name it as fonts.
Download fonts from internet and store them in fonts folder.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center"
    tools:context="com.example.hss_24.font.MainActivity">

    <TextView
        android:id="@+id/txt_1"
        android:textSize="28sp"
        android:layout_margin="10dp"
        android:gravity="center"
        android:textColor="@color/colorPrimaryDark"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Android Lovers" />

    <TextView
        android:id="@+id/txt_2"
        android:textSize="28sp"
        android:layout_margin="10dp"
        android:gravity="center"
        android:textColor="#000000"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Android Lovers" />

    <TextView
        android:id="@+id/txt_3"
        android:textSize="28sp"
        android:layout_margin="10dp"
        android:gravity="center"
        android:textColor="@color/colorPrimary"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Android Lovers" />

    <TextView
        android:id="@+id/txt_4"
        android:textSize="28sp"
        android:layout_margin="10dp"
        android:gravity="center"
        android:textColor="@color/colorAccent"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Android Lovers" />

</LinearLayout>

Set the Typeface to the textview's in the MainActivity.java file.

File: MainActivity.java:

import android.graphics.Typeface;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView textView = (TextView) findViewById(R.id.txt_1);
        TextView textView_2 = (TextView) findViewById(R.id.txt_2);
        TextView textView_3 = (TextView) findViewById(R.id.txt_3);
        TextView textView_4 = (TextView) findViewById(R.id.txt_4);

        //  set the typeface to the textview's
        Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/CompletelyNonsense.ttf");
        textView.setTypeface(typeface);

        Typeface typeface_2 = Typeface.createFromAsset(getAssets(), "fonts/CornerDark.ttf");
        textView_2.setTypeface(typeface_2);

        Typeface typeface_3 = Typeface.createFromAsset(getAssets(), "fonts/LastFeast.otf");
        textView_3.setTypeface(typeface_3);

        Typeface typeface_4 = Typeface.createFromAsset(getAssets(), "fonts/masterofbreak.ttf");
        textView_4.setTypeface(typeface_4);
    }
}

Date and Time Picker in Android

noreply@blogger.com (Unknown) — Thu, 03 Mar 2016 06:59:00 +0000

Date and Time Picker example In Android

In this tutorial we will learn to implement date and time picker with a simple example in Android Studio.

Example:

In this example we have two Button's and two TextView's, button's are to pick date and time and textview's is to show date and time when user hits the button.
Create a new project as DateAndTimePicker in Android Studio.
Design the main layout as follows.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.hss_24.dateandtimepicker.MainActivity">

    <Button
        android:id="@+id/btn_time"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="pick time" />

    <TextView
        android:id="@+id/txt_time"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:layout_marginTop="10dp"
        android:gravity="center"
        android:textColor="@color/colorAccent"
        android:textStyle="bold" />

    <Button
        android:id="@+id/btn_date"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="pick date" />

    <TextView
        android:id="@+id/txt_date"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:layout_marginTop="10dp"
        android:gravity="center"
        android:textColor="@color/colorAccent"
        android:textStyle="bold" />

</LinearLayout>


Do the following code in java file.
We need Date picker and Time picker dialog's to select the date and time.

File: MainActivity.java:

import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.TimePicker;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {

    Button date, time;
    TextView txt_date, txt_time;
    // variables for storing date and time
    private int mYear, mMonth, mDay, mHour, mMinute;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        date = (Button) findViewById(R.id.btn_date);
        time = (Button) findViewById(R.id.btn_time);

        txt_date = (TextView) findViewById(R.id.txt_date);
        txt_time = (TextView) findViewById(R.id.txt_time);

        date.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v == date) {

                    // get Current Date
                    final Calendar c = Calendar.getInstance();
                    mYear = c.get(Calendar.YEAR);
                    mMonth = c.get(Calendar.MONTH);
                    mDay = c.get(Calendar.DAY_OF_MONTH);

                    // Launch Date Picker Dialog
                    DatePickerDialog datePickerDialog = new DatePickerDialog(MainActivity.this,
                            new DatePickerDialog.OnDateSetListener() {

                                @Override
                                public void onDateSet(DatePicker view, int year,
                                                      int monthOfYear, int dayOfMonth) {
                                    // Display Selected date in textbox
                                    txt_date.setText(dayOfMonth + "-"
                                            + (monthOfYear + 1) + "-" + year);

                                }
                            }, mYear, mMonth, mDay);
                    datePickerDialog.show();
                }

            }

        });

        time.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v == time) {

                    //  get Current Time
                    final Calendar c = Calendar.getInstance();
                    mHour = c.get(Calendar.HOUR_OF_DAY);
                    mMinute = c.get(Calendar.MINUTE);

                    // Launch Time Picker Dialog
                    TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this,
                            new TimePickerDialog.OnTimeSetListener() {

                                @Override
                                public void onTimeSet(TimePicker view, int hourOfDay,
                                                      int minute) {
                                    // Display Selected time in textbox
                                    txt_time.setText(hourOfDay + ":" + minute);

Spinner in Android

noreply@blogger.com (Unknown) — Tue, 01 Mar 2016 08:36:00 +0000

Spinner In Android

In this tutorial we will learn to implement Spinner with a simple example in Android Studio. Spinner is a drop down list which allows the user to pick one item from it. In this example we will create a simple spinner which shows a drop down list of android OS and when we select one item then the image of the similar OS will be shown below.

Example:

Create a new project in Android Studio and name it as Spinner.
Design a spinner and image_view in a main layout, as follows.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.hss_24.spinner.MainActivity">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="10dp"
        android:text="AndroidLovers"
        android:textSize="28sp"
        android:textStyle="bold" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="Please select your Android OS"
        android:textSize="20sp" />

    <Spinner
        android:id="@+id/spinner"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_marginTop="10dp">

    </Spinner>

    <ImageView
        android:id="@+id/image_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp" />

</LinearLayout>


Create a integer array in strings.xml, as follows.

File: strings.xml:

<resources>
    <string name="app_name">Spinner</string>

    <integer-array name="image_list">
        <item>@drawable/cupcake</item>
        <item>@drawable/donut</item>
        <item>@drawable/eclair</item>
        <item>@drawable/froyo</item>
        <item>@drawable/gingerbread</item>
        <item>@drawable/honeycomb</item>
        <item>@drawable/icecream_sandwich</item>
        <item>@drawable/jellybean</item>
        <item>@drawable/kitkat</item>
        <item>@drawable/lollipop</item>
        <item>@drawable/marsh_mallow</item>
    </integer-array>

</resources>


Now its time to code, do the following in java file.

File: MainActivity.java:
import android.content.res.TypedArray;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.Spinner;

public class MainActivity extends AppCompatActivity {

    private ImageView imageView;
    private Spinner spinner;
    private TypedArray imgs;

    //    Spinner dropdown items
    String[] android_names = {"Cupcake", "Donut", "Eclair", "Froyo", "Ginger Bread", "Honeycomb",
            "IceCream Sandwich", "Jelly Bean", "Kitkat", "Lollipop", "MarshMallow"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        spinner = (Spinner) findViewById(R.id.spinner);
        imageView = (ImageView) findViewById(R.id.image_view);

        // get image list from array defined in strings.xml
        imgs = getResources().obtainTypedArray(R.array.image_list);

        // create and set adapter for spinner
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, android_names);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);


        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                // display images when spinner item is selected
                imageView.setImageResource(imgs.getResourceId(spinner.getSelectedItemPosition(), -1));
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {

            }
        });
    }
}

CheckBox in Android

noreply@blogger.com (Unknown) — Mon, 29 Feb 2016 14:01:00 +0000

Checkbox In Android

In this tutorial we will deal with the checkbox in Android with an example. Checkboxes are widely used in Android to activate or deactivate something and to select something from a group of items.

Example:

Create a new project and name it as Checkbox.
Design a main layout as follows.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.hss_24.checkbox.MainActivity">

    <TextView
        android:text="AndroidLovers"
        android:textSize="28sp"
        android:gravity="center"
        android:padding="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <TextView
        android:text="Please select your Sport"
        android:textSize="24sp"
        android:gravity="center"
        android:layout_marginBottom="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <CheckBox
        android:id="@+id/chk1"
        android:text="Cricket"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <CheckBox
        android:id="@+id/chk2"
        android:text="Football"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <CheckBox
        android:id="@+id/chk3"
        android:text="Hockey"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <CheckBox
        android:id="@+id/chk4"
        android:text="Swimming"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <LinearLayout
        android:orientation="horizontal"
        android:gravity="center"
        android:layout_margin="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

    <Button
        android:id="@+id/btn_select"
        android:text="select"
        android:layout_marginRight="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <Button
        android:id="@+id/btn_cancel"
        android:text="cancel"
        android:layout_marginLeft="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    </LinearLayout>

    <TextView
        android:id="@+id/result"
        android:textStyle="bold"
        android:textColor="@color/colorAccent"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>


In this example we will show the selected item in a Textview with the help a StringBuffer.
Write the following code in java file as follows.

File: MainActivity.java:

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {
    CheckBox chk_cricket, chk_football, chk_hockey, chk_swimming;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        chk_cricket = (CheckBox) findViewById(R.id.chk1);
        chk_football = (CheckBox) findViewById(R.id.chk2);
        chk_hockey = (CheckBox) findViewById(R.id.chk3);
        chk_swimming = (CheckBox) findViewById(R.id.chk4);

        Button btn_select = (Button) findViewById(R.id.btn_select);
        Button btn_cancel = (Button) findViewById(R.id.btn_cancel);

        btn_select.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                StringBuilder result = new StringBuilder();
                result.append("You have selected:");
                if (chk_cricket.isChecked()) {
                    result.append("\nCricket");
                }
                if (chk_football.isChecked()) {
                    result.append("\nFootball");
                }
                if (chk_hockey.isChecked()) {
                    result.append("\nHockey");
                }
                if (chk_swimming.isChecked()) {
                    result.append("\nSwimming");
                }

                TextView text_result = (TextView) findViewById(R.id.result);
                text_result.setText(result);
            }
        });

        btn_cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
            }
        });
    }
}

Custom Alert Dialog in Android

In this tutorial we will learn how to build the custom alert dialog with example. In custom alert dialog we will design a new custom layout and inflate the layout in dailog class.

Example:

Create a new layout as custom_dailog.xml.
Design a custom layout as follows.

File: custom_layout.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:background="#ffffffff"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="130dp"
        android:background="#303F9F"
        android:gravity="center"
        android:orientation="vertical">

        <TextView
            android:id="@+id/delete"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="Delete this item"
            android:textColor="#ffffff"
            android:textSize="28sp" />


        <ImageView
            android:id="@+id/img_delete"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:gravity="center"
            android:scaleType="center"
            android:src="@drawable/delete" />
    </LinearLayout>

    <TextView
        android:id="@+id/text_dialog"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView"
        android:layout_margin="20dp"
        android:gravity="center"
        android:text="Do you want to delete this item?"
        android:textColor="#ff000000"
        android:textSize="18sp" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="20dp"
        android:gravity="center"
        android:orientation="horizontal">

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="wrap_content"
            android:layout_height="40dp"
            android:layout_marginRight="10dp"
            android:background="#3F51B5"
            android:text="YES"
            android:textColor="#ffffffff" />

        <Button
            android:id="@+id/btn_no"
            android:layout_width="wrap_content"
            android:layout_height="40dp"
            android:layout_marginLeft="10dp"
            android:background="#3F51B5"
            android:text="NO"
            android:textColor="#ffffffff" />

    </LinearLayout>

</LinearLayout>


Now do the code for the custom dialog as follows.

File: MainActivity.java:

Button custom_button = (Button) findViewById(R.id.button_custom);
custom_button.setOnClickListener(new View.OnClickListener() {
    @Override    
        public void onClick(View v) {
        final Dialog dialog = new Dialog(MainActivity.this);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.custom_dialog);
        dialog.setCancelable(true);
        dialog.show();

        Button yes = (Button) dialog.findViewById(R.id.btn_yes);
        yes.setOnClickListener(new View.OnClickListener() {
            @Override            
                public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "Deleted", Toast.LENGTH_LONG).show();
                dialog.cancel();
            }
        });

        Button no = (Button) dialog.findViewById(R.id.btn_no);
        no.setOnClickListener(new View.OnClickListener() {
            @Override            
                public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "Not deleted", Toast.LENGTH_LONG).show();
                dialog.cancel();
            }
        });
    }
});


Run the Application and see the output

Alert Dialog

noreply@blogger.com (Unknown) — Tue, 23 Feb 2016 13:55:00 +0000

Alert Dialog in Android

In this tutorial we will learn how to create an Alert Dialog in Android with a simple example. Basically a Dialog is a small pop up window that prompts a user to make the decision.

Example:

Create a new project as AlertDialog in Android Studio.
Design a Button in activity_main.xml, as follows

File: activity_main.xml:

<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"    
xmlns:tools="http://schemas.android.com/tools"    
android:layout_width="match_parent"    
android:layout_height="match_parent"    
android:gravity="center"    
android:paddingBottom="@dimen/activity_vertical_margin"    
android:paddingLeft="@dimen/activity_horizontal_margin"    
android:paddingRight="@dimen/activity_horizontal_margin"    
android:paddingTop="@dimen/activity_vertical_margin"    
tools:context="com.example.hss_24.alertdialog.MainActivity">

<Button       
android:id="@+id/button"       
android:text="Alert Dialog"       
android:layout_width="match_parent"       
android:layout_height="wrap_content" />
</LinearLayout>

Now we have to create a Alertdialog by using Builder and set the Positive and Negative Buttons respectively
Do the following in MainActivity.java file.

File:MainActivity.java:

import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button button = (Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override            
                public void onClick(View v) {
                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                builder.setTitle("CONFIRM DELETE");
                builder.setMessage("Are you sure you want to delete");
                builder.setCancelable(true);

                builder.setPositiveButton(
                        "Yes",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                Toast.makeText(getApplicationContext(), "Deleted", Toast.LENGTH_LONG).show();
                                dialog.cancel();
                            }
                        });

                builder.setNegativeButton(
                        "No",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                Toast.makeText(getApplicationContext(), "Not deleted", Toast.LENGTH_LONG).show();
                                dialog.cancel();
                            }
                        });

                AlertDialog alert = builder.create();
                alert.show();
            }
        });
    }
}


Now run the Application.

Animated Splash Screen In Android

noreply@blogger.com (Unknown) — Mon, 22 Feb 2016 11:05:00 +0000

Splash Screen In Android

In this tutorial we will learn how to implement Splash Screen in Android with an example.

Android Splash Screen is used to show the user before the App loads completely, some people use it to show their App company logo for the couple of minute.

Splash Screen is an Activity that will show for the set time if the set time ends it will re direct to the Main screen.

Example:

Create a new project.
Do nothing in activity_main.xml and MainActivity.java.
Create a new Activity as SplashScreen.
In splash.xml do the following.

File: splash.xml:

<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"    
android:layout_width="match_parent"    
android:layout_height="match_parent"    
android:background="@drawable/bg"    
android:gravity="center"    
android:orientation="vertical">

<TextView        
android:id="@+id/text"        
android:layout_width="match_parent"        
android:layout_height="wrap_content"        
android:gravity="center_horizontal"        
android:text="AndroidLovers"        
android:textSize="40sp"        
android:textStyle="bold" />

</LinearLayout>


Create a new Directory for storing Animation files as anim, right click on  res -> New -> Directory and name it as anim.
Create a Animation xml, right click on anim -> New -> Animation resource file and name it as fade.
Do the following in fade.xml.

File: fade.xml:

<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator">

<alpha        
android:duration="2000"        
android:fromAlpha="0"        
android:toAlpha="1">
    </alpha>

<alpha        
android:duration="2000"        
android:fromAlpha="1"        
android:startOffset="2000"        
android:toAlpha="0">       
    </alpha>

</set>

</set>


Now lets go for coding, do the following in SlpashScreen.java.

File: SplashScreen.java:

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.TextView;

public class SplashScreen extends Activity {
    TextView textView;

    @Override    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        textView = (TextView) findViewById(R.id.text);
        Thread timer = new Thread() {
            public void run() {
                try {
                    Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fade);
                    textView.startAnimation(animation);
                    sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                } finally {
                    Intent i = new Intent(SplashScreen.this, MainActivity.class);
                    startActivity(i);
                }
            }
        };
        timer.start();
    }

    @Override    protected void onPause() {
        super.onPause();
        finish();

    }

}


We have to set SplashScreen as launcher and MainActivity as default in Manifest, so lets go to Manifest and change the following.

File: Manifest:<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.hss_24.splashscreen">

    <application        
android:allowBackup="true"        
android:icon="@mipmap/ic_launcher"        
android:label="@string/app_name"        
android:supportsRtl="true"        
android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
        <activity android:name=".SplashScreen">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>



Run the Application.

Broadcast Receiver In Android

noreply@blogger.com (Unknown) — Thu, 18 Feb 2016 07:14:00 +0000

Broadcast Receiver

Broadcast receivers responds to the broadcast messages to the system itself. for example if you plugged in your ear phone to your mobile it will show you a message that ear phones are plugged in.

There are two important steps, they are:

Creating the broadcast receiver.
Registering the broadcast receiver.

Creating the broadcast receiver:

Create a class called Receiver, right click on java->New->Java class->main->class name as Receiver.
Extend a BroadcastReceiver in Receiver class.
Override a method called onReceive(), by hitting ctrl+o in the class Receiver.

public class Receiver extends BroadcastReceiver {
    @Override    public void onReceive(Context context, Intent intent) {
    }
}


Register Broadcast receiver in Mainfest.

<receiver android:name=".Receiver">
    <intent-filter>
        <action android:name="android.intent.action.AIRPLANE_MODE"/>

    </intent-filter>
</receiver>



Example:

Create a new project, we have do changes only in Manifest and Java class no need to design in xml.
Create a new java class as Receiver and do the following.

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

/** * Created by HSS-24 on 2/17/2016. */

public class Receiver extends BroadcastReceiver {
    @Override    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context,"Airplane mode on",Toast.LENGTH_LONG).show();
    }
}



Register in Manifest

<activity android:name=".MainActivity">

<intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver android:name=".Receiver">
            <intent-filter>
                <action android:name="android.intent.action.AIRPLANE_MODE"/>

            </intent-filter>
        </receiver>
    </application>

</manifest>



Now when you hit the Airplane mode in your mobile to switch on or off it should show a toast as Airplane mode on
Run the App.

Grid View

noreply@blogger.com (Unknown) — Tue, 16 Feb 2016 07:33:00 +0000

GridView In Android

In this tutorial we will learn how to implement GridView in Android Studio with simple example.

GridView:

GridView is a viewgroup that displays items in a two dimensional scrollable grid. The grid items are automatically inserted to the layout using Adapter.

Create a new project and name it as Gridview.
In the activity_main.xml define the GridView and it components.

File: activity_main.xml:

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"    
xmlns:tools="http://schemas.android.com/tools"    
android:layout_width="match_parent"    
android:layout_height="match_parent"    
tools:context="com.example.hss_24.gridview.MainActivity">

<GridView        
android:id="@+id/grid_view"        
android:layout_width="match_parent"        
android:layout_height="match_parent"        
android:numColumns="2">

    </GridView>

</RelativeLayout>

Create a new layout and name it as grid_cell.
Define ImageView and TextView in the layout to display images and texts.

File: grid_cell.xml:

<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"    
android:layout_width="match_parent"    
android:layout_height="match_parent"    
android:orientation="vertical"    
android:padding="10dp">

<ImageView        
android:id="@+id/image"        
android:layout_width="180dp"        
android:layout_height="180dp" />

<TextView        
android:id="@+id/text"        
android:layout_width="wrap_content"        
android:layout_height="wrap_content"        
android:text="dddd"        
android:textColor="#303F9F"        
android:textStyle="bold" />

</LinearLayout>

</LinearLayout>

Do the following code in the java file MainActivity.java.

File: MainActivity.java:

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    String [] names = {"Cupcake","Donut","Eclair","Froyo","Ginger Bread","Honeycomb",
            "IceCream Sandwich","Jelly Bean","Kitkat","Lollipop","MarshMallow"};

    int [] images = {R.drawable.cupcake,R.drawable.donut,R.drawable.eclair,R.drawable.froyo,R.drawable.gingerbread,
            R.drawable.honeycomb,R.drawable.icecream_sandwich,R.drawable.jellybean,R.drawable.kitkat,
            R.drawable.lollipop,R.drawable.marsh_mallow};

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        GridView gridView = (GridView)findViewById(R.id.grid_view);
        gridView.setAdapter(new MyAdapter());
    }

    public class MyAdapter extends BaseAdapter {
        public MyAdapter() {
            super();
        }

        @Override        
            public int getCount() {
            return names.length;
        }

        @Override        
            public Object getItem(int position) {
            return null;
        }

        @Override        
            public long getItemId(int position) {
            return 0;
        }

        @Override        
            public View getView(int position, View convertView, ViewGroup parent) {

            LayoutInflater inflater = LayoutInflater.from(MainActivity.this);
            convertView = inflater.inflate(R.layout.grid_cell,null);

            ImageView imageView = (ImageView)convertView.findViewById(R.id.image);
            TextView textView = (TextView)convertView.findViewById(R.id.text);

            imageView.setImageResource(images[position]);
            textView.setText(names[position]);
            return convertView;
        }
    }
}


Run the Application.
Now we have learned successfully the GridView in Android.
