2013-08-03T01:54:00.000-07:00

Solution 1:

View activityRootView = fragmentView.findViewById(R.id.root_view);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener( new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {

Rect r = new Rect();
  activityRootView.getWindowVisibleDisplayFrame(r);

int screenHeight = activityRootView.getRootView().getHeight();
Log.e("screenHeight",String.valueOf(screenHeight));
  int heightDiff = screenHeight - (r.bottom - r.top);
  Log.e("heightDiff",String.valueOf(heightDiff));
boolean visible = heightDiff > screenHeight / 3;

Log.e("visible",String.valueOf(visible));

if(visible)
{ if true ,do your stuff here !}
else
{ else, do your stuff here }

}
});

Solution 2:

View activityRootView = fragmentView.findViewById(R.id.root_view);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(
new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
if (heightDiff > 150)
{ // if more than 150 pixels, its probably a keyboard...
do your stuff , if keyboard visible
}
else
{

}
}
