我们可以设置持续时间长键preSS监听器？我要的是，如果用户保持触摸屏幕，持续3秒，然后我的长键preSS监听器应该触发，打开我的弹出设置。

Can we set duration for Long key press listener? What i want is, if user keeps touching the screen for 3 sec then my long key press listener should trigger and open my pop up for setting.

在此先感谢。

推荐答案

覆盖onTouch监听器，然后处理$ P $，公布事件，并在pssed按钮$ P $设置定时器（事件==pressed）

Override onTouch Listener ,then handle pressed,released event and set timer during button pressed (event == "pressed")

private Timer timer;

 public LongClickTimer(int seconds) {
            timer = new Timer();
            timer.schedule(new LongClickTask(), seconds *1000);         
        }
 class LongClickTask extends TimerTask {
            public void run() { 
             // do what you want            
                timer.cancel(); 
            }
        }
     button.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.v(TAG, "EVENT" + event.toString());
                    if(event.getAction == 2) {// pressed                        
                    new LongClickTimer(5); // schedule for 5 seconds
                    }else{          
                     timer.cancel();
                    }
               return false;
              }
           });
