Gestures Detector

noreply@blogger.com (P.Vishnupriyan) — Thu, 6 Sep 2012 22:30:00 -0700

Gestures are patterns drawn by the user on the screen. Simple gestures include tap, scroll, swipe, etc. Complex gestures are more complex patterns drawn on the screen. In Android we can detect simple gestures using GestureDetector class.

Here i am going to create a simple Gestures Detector having scroll and flip on the basis of the Double-tap.

Create an activity -> FlipperActivity.java

package com.samples.gesturedetectorsample;

import java.util.ArrayList;
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.os.Vibrator;

import android.view.ViewGroup.LayoutParams;
import android.view.animation.Animation;
import android.view.animation.OvershootInterpolator;
import android.view.animation.TranslateAnimation;
import android.widget.TextView;
import android.widget.ViewFlipper;

public class FlipperActivity extends Activity

final private int SWIPE_MIN_DISTANCE = 100;

Simple Android Application Launcher

noreply@blogger.com (P.Vishnupriyan) — Fri, 31 Aug 2012 05:24:00 -0700

A Launcher presents the main view of the phone and is responsible for starting other apps and hosting live widgets.

Here the resource (res) consist of "drawable", "layout", "menu", "values" Folders.

Use the following codes in "layout"

app.xml

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

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent"

android:layout_height="wrap_content">

<ImageView

android:id="@+id/app_icon"

android:layout_width="48px"

android:layout_height="48px"

android:padding="3px"

android:scaleType="fitXY"/>

<LinearLayout

android:layout_width="fill_parent"

android:layout_height="fill_parent">

<TextView

android:id="@+id/app_name"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:gravity="center_vertical"/>

</LinearLayout>

main.xml

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent">

<ListView

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:id="@android:id/list"/>

</LinearLayout>

Use the following to the "menu" folder

menu.xml

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

<menu

xmlns:android="http://schemas.android.com/apk/res/android">

<item android:id="@+id/menu_about"

android:titleCondensed="@string/menu_about"

android:title="@string/menu_about_desc"

android:icon="@android:drawable/ic_menu_help"></item>

</menu>

Use the following codes in "values"

string.xml

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

<string name="app_name">App Launcher</string>

<string name="app_desc">Simple application to show how to enumerate and launch external application</string>

<string name="menu_about">About</string>

<string name="menu_about_desc">About App Launcher</string>

define the server and image path URL to the Webservicehelper's public class

Webservicehelper.JAVA

public static final String UPLOADIMAGE = SERVER_NAME
+ "/smadws/uploadimages.aspx?pid=";

(the url is based in the wbservice provided)

NOTE : the above method is to update the image by passing the the users key, For normal update please avoid the data passed through Bundle values in the above java code, "ie: cKey"

How To Create A Spinner With Data Bind In Android.

noreply@blogger.com (P.Vishnupriyan) — Wed, 28 Dec 2011 02:03:00 -0800

Create the Spinner code in "main.xml". This for the UI (spinner design).

<RelativeLayout >
<TextView
android:id="@+id/textView1"
android:layout_width="120dip"
android:layout_marginTop="10dip"
style="@style/FixAppointMentDettextView"
android:layout_height="wrap_content"
android:text="Blood Group" />

</RelativeLayout>

<LinearLayout android:layout_height="wrap_content" android:layout_width="180dip" >
<Spinner

android:id="@+id/add_pa_bloodgroup_spinner"
android:layout_width="180dip"
android:textSize="90dip"
android:layout_height="wrap_content" >
</Spinner>
</LinearLayout>

..............................................................................................................................................................

Create an array of data.... that display in the popup of the spinner.

res/values/String.xml

<string-array name="BloodGroup" >
<item>Select</item>
<item>A+</item>
<item>A-</item>
<item>B+</item>
<item>B-</item>
<item>AB+</item>
<item>AB-</item>
<item>O+</item>
<item>O-</item>
</string-array>

....................................................................................................................................................................

Add the java code in the onCreate of .java

Spinner spinner = (Spinner) findViewById(R.id.add_pa_bloodgroup_spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.BloodGroup, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

....................................................................................................................................................................

Create A callback method in .java.

public class MyOnItemSelectedListener implements OnItemSelectedListener {

public void onItemSelected(AdapterView<?> parent,
View view, int pos, long id) {
blood = parent.getItemAtPosition(pos).toString();
System.out.println("555555555VALUE Blood" + blood);
}

public void onNothingSelected(AdapterView parent) {

}
}

..................................................................................................................................................................

Use this on the .java's onCreate part.

add_pa_bloodgroup_spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

How To Create An Alert Box in Android.

noreply@blogger.com (P.Vishnupriyan) — Wed, 28 Dec 2011 00:52:00 -0800

Create a "main.xml" data in your layout folder.

<LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:weightSum="1"><Button android:id="@+id/button1" android:text="Button" android:layout_height="wrap_content" android:layout_width="wrap_content"/></LinearLayout>

................................................................................................................................

Use the following code in your .java page (class file)

Here (AlertActivity.java)

public class AlertActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
AlertDialog.Builder builder = new AlertDialog.Builder(AlertActivity.this);
builder.setMessage("are you sure want to exit");
builder.setCancelable(false);
builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {

AlertActivity.this .finish();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();

}

});

}

}
