How it is possible.?

Answer 1

First create a GestureDetector and a listener. Then bind it to your class that extends GestureDetector.SimpleOnGestureListener.

private GestureDetector detector;  
private ImageView mImageView;

@Override  
public void onCreate(Bundle savedInstanceState) {  
  super.onCreate(savedInstanceState);  
  detector = new GestureDetector(this, new MyGesturesListener());  
  // TODO find your image view
  mImageView.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            detector.onTouchEvent(event);
            return true;
        }
    });
}

Then you can implement the methods of different gestures:

class MyGesturesListener extends GestureDetector.SimpleOnGestureListener{  
  @Override  
  public boolean onSingleTapUp(MotionEvent ev) { 
    // TODO handle single tap 
    return true;  
  }  
  @Override  
  public boolean onDoubleTap(MotionEvent ev) {  
    // TODO handle double tap
    return true;  
  }
}
