android - 如何在 setOnLongClickListener 中获取 onTouch x 和 y 值？

Question

运行时我改变了背景图像(设置背景)。在图像中，我使用 Touch Listener 执行了操作。但就我而言，我需要对 Touch 事件执行另一个操作。为此，我需要继续长按事件。给我建议，任何其他想法。

来自 here 的回答:

final Handler handler = new Handler(); 
Runnable mLongPressed = new Runnable() { 
    public void run() { 
        Log.i("", "Long press!");
        if(myEvent!=null)
        {
           int requiredXvalue=myEvent.getX();               
           int requiredYvalue=myEvent.getY();

        }
    }   
};
MotionEvent myEvent;
@Override
public boolean onTouchEvent(MotionEvent event, MapView mapView){
    if(event.getAction() == MotionEvent.ACTION_DOWN)
    {
        handler.postDelayed(mLongPressed, 1000);
        myEvent=event;
    }
    if((event.getAction() == MotionEvent.ACTION_MOVE)||(event.getAction() == MotionEvent.ACTION_UP))
        handler.removeCallbacks(mLongPressed);
    return super.onTouchEvent(event, mapView);
}

或

您可以使用手势检测器作为回答 here :

final GestureDetector gestureDetector = new GestureDetector(new GestureDetector.SimpleOnGestureListener() {
    public void onLongPress(MotionEvent e) {
        Log.e("", "Longpress detected");
        int requiredXvalue=e.getX();               
        int requiredYvalue=e.getY();
    }
});

public boolean onTouchEvent(MotionEvent event) {
    return gestureDetector.onTouchEvent(event);
};
