Answer 1

you can use on long click instead of using double click by override this method

 abstract boolean onLongClick(View v)

Called when a view has been clicked and held.

Answer 2

I did a simple solution like that -

buttonTab.setOnClickListener(new View.OnClickListener() {
            int count = 0;
            Handler handler = new Handler();
            Runnable runnable = () -> count = 0;

            @Override
            public void onClick(View v) {
                if (!handler.hasCallbacks(runnable))
                    handler.postDelayed(runnable, 500);
                if(count==2){
                    /*View is double clicked.Now code here.*/
                }
            }
        });

Answer 3

Try to use GestureDetector.

public class MyView extends View {

GestureDetector gestureDetector;

public MyView(Context context, AttributeSet attrs) {
    super(context, attrs);
    // creating new gesture detector
    gestureDetector = new GestureDetector(context, new GestureListener());
}

// skipping measure calculation and drawing

// delegate the event to the gesture detector
@Override
public boolean onTouchEvent(MotionEvent e) {
    //Single Tap
    return gestureDetector.onTouchEvent(e);
}


private class GestureListener extends GestureDetector.SimpleOnGestureListener {

    @Override
    public boolean onDown(MotionEvent e) {
        return true;
    }

    // event when double tap occurs
    @Override
    public boolean onDoubleTap(MotionEvent e) {
        float x = e.getX();
        float y = e.getY();

        Log.d("Double Tap", "Tapped at: (" + x + "," + y + ")");

        return true;
    }

}
