Why android onLongPress always is fired after onDoubleTap?

Question

I have onLongPress and onDoubleTap actions placed on the button according to this code:

...
GestureDetector detector = new GestureDetector(this, new TapDetec         


        

Answer 1

Technically this shouldn't happen

case MotionEvent.ACTION_DOWN:
        mLastMotionX = x;
        mLastMotionY = y;
        mCurrentDownEvent = MotionEvent.obtain(ev);
        mAlwaysInTapRegion = true;
        mInLongPress = false;

        if (mIsLongpressEnabled) {
            mHandler.removeMessages(LONG_PRESS);
            mHandler.sendEmptyMessageAtTime(LONG_PRESS, mCurrentDownEvent.getDownTime()
                    + tapTime + longpressTime);
        }
        mHandler.sendEmptyMessageAtTime(SHOW_PRESS, mCurrentDownEvent.getDownTime() + tapTime);

because on the ACTION_DOWN or ACTION_UP event, all of the LONG_PRESS messages events are removed from the queue. So on the second tap the following code will remove the long press events.

 mHandler.removeMessages(LONG_PRESS);

Ninja edit : hacky workaround for your problem

     @Override
     public void onLongPress(MotionEvent e) {
        if(MainActivity.this.hasWindowFocus())
        {
            Log.d("Touchy", "Long tap");    
        }
    }
