OnLongPress event is working only for first time

Question

I am developing a game in which I want to perform certain operations when user single touch the screen, and some other operations when user long press the screen. For this, I have created a Gesture Detector class and add events to them.

Surface View Class

public class MySurfaceView extends SurfaceView implements SurfaceHolder.Callback {
public MySurfaceView(Context context, AttributeSet attrs) {
gestureDetector = new GestureDetector(context, new GestureListener(this));
}


@Override
public boolean onTouchEvent(MotionEvent event) {
     Log.d(TAG,"Inside Touch Event");
    float lasttouched_X, lasttouched_Y;
    Card localcard;
    int index=-1;
    Log.d(TAG,"Inside OnTouch event");
    gestureDetector.onTouchEvent(event);
    return true;
  }
 }

Gesture Detector class

 class GestureListener extends GestureDetector.SimpleOnGestureListener{
private static final String TAG = GestureListener.class.getSimpleName();  // To get name of class in Logging
    MySurfaceView mySurfaceView;



    public GestureListener(MySurfaceView paramMySurfaceView)
    {
        mySurfaceView=paramMySurfaceView;
    }

@Override
public void onLongPress(MotionEvent e) {

    Log.d(TAG,"Inside Long Pressed event");
        mySurfaceView.addTouchedCardToLongTouched(e);
}


@Override
public boolean onDown(MotionEvent e) {

  // don't return false here or else none of the other
  // gestures will work

    return  false;
}


@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
    mySurfaceView.swapSingleTouchCard(e);
    return false;
}

@Override
public boolean onDoubleTap(MotionEvent e) {
    Log.d(TAG,"Inside On Double Tap event");
    return false;
}

}

OnLongPress event is working only for first time, after that whenever i long press touch screen, it is firing onSingleTapConfirmed event.I am not able to understand why this is happening.

Please let me know why this is happening. Thanks in advance.

@GastónSaillén that solution didn't worked for me. That solution is for when long press event is getting triggered, irrespective which event trigger by user, however in my case long pressed stop getting trigger after first time. — Chetan Mehra, Dec 02 '18 at 18:44
How about following your own instructions, and returning `true` to `onDown`? — lionscribe, Dec 03 '18 at 05:51
@lionscribe if i did that then Long Press event will never work, i already asked that question here https://stackoverflow.com/questions/52576818/onlongpress-is-not-working-with-our-touch-events?rq=1 — Chetan Mehra, Dec 03 '18 at 07:11
@lionscribe even after changing onDown to true it is still not working. — Chetan Mehra, Dec 03 '18 at 19:26
