Double-tapping in Android can be identified using the GestureDetector class. The GestureDetector class provides methods for detecting gestures such as double-tap, long press, fling, and scroll. To detect double-tapping, you need to create an instance of GestureDetector and implement the OnDoubleTapListener interface. The gesture detector will then listen for double-tap events and invoke the onDoubleTap() method when a double-tap is detected. Here is an example code snippet:

GestureDetector gd = new GestureDetector(this, new GestureDetector.SimpleOnGestureListener() {
    @Override
    public boolean onDoubleTap(MotionEvent e) {
        // Double tap detected
        return super.onDoubleTap(e);
    }
});

// Pass touch events to the gesture detector
@Override
public boolean onTouchEvent(MotionEvent event) {
    gd.onTouchEvent(event);
    return super.onTouchEvent(event);
}

In this example, the onDoubleTap() method is called when the user double-taps the screen. You can perform any action you want inside this method.
