Detecting a long press with Android

The Solution to Detecting a long press with Android is


GestureDetector is the best solution.

Here is an interesting alternative. In onTouchEvent on every ACTION_DOWN schedule a Runnable to run in 1 second. On every ACTION_UP or ACTION_MOVE, cancel scheduled Runnable. If cancelation happens less than 1s from ACTION_DOWN event, Runnable won't run.

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);
}
