Android에서 onTouchEvent()를 사용하여 길게 누르기를 감지하는 방법은 무엇입니까?

<code class="java">@Override
public boolean onTouchEvent(MotionEvent event) {
    // Register and check for long presses
    GestureDetector gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onLongPress(MotionEvent e) {
            // Perform long press action
            return true;
        }
    });
    gestureDetector.onTouchEvent(event);
    return super.onTouchEvent(event);
}</code>

<code class="java">final Handler handler = new Handler();
Runnable mLongPressed = new Runnable() { 
    public void run() { 
        Log.i("", "Long press!");
    }   
};

@Override
public boolean onTouchEvent(MotionEvent event, MapView mapView){
    if(event.getAction() == MotionEvent.ACTION_DOWN)
        handler.postDelayed(mLongPressed, ViewConfiguration.getLongPressTimeout());
    if((event.getAction() == MotionEvent.ACTION_MOVE)||(event.getAction() == MotionEvent.ACTION_UP))
        handler.removeCallbacks(mLongPressed);
    return super.onTouchEvent(event, mapView);
}</code>
