--------------------------------------

 import android.view.GestureDetector;
 import android.view.MotionEvent;
 
public class OnDoubleClick extends GestureDetector.SimpleOnGestureListener{
 @Override
public boolean onDoubleTap(MotionEvent e) {
//TODO
return true;
 }
 // @Override
 // public boolean onDoubleTapEvent(MotionEvent e) {
 // return super.onDoubleTapEvent(e);
 // }
 }
