how to hide things after certain time in android studio

问题

我在 Android Studio 中正在创建一个视频播放器。我希望在5秒后隐藏按钮、布局和媒体控制器，并且我正在使用手势来控制不同的属性，但问题是，当我在一定时间内应用2到3个手势时，5秒后按钮和媒体控制器开始闪烁。我在屏幕上使用以下代码：

  1. centerlayout.setOnTouchListener(new LinearLayout.OnTouchListener(){
  2.     @Override
  3.     public boolean onTouch(View v, MotionEvent m) {
  4.         if (gestureDetectorc.onTouchEvent(m)) {
  5.             if(m.getAction()==MotionEvent.ACTION_UP){
  6.                 handler.postDelayed(new Runnable() {
  7.                     @Override
  8.                     public void run() {
  9.                         hide();
  10.                     }
  11.                 },5000);
  12.             }
  13.         }
  14.         return true;
  15.     }
  16. });

I am creating a video player in android studio. I want to hide buttons, layout and media controller after 5 seconds and I am using gestures for different properties but the issue is that when I apply 2 to 3 gestures in a certain time, after 5 seconds the buttons and media controller start blinking. I use this code for stying on screen

  1. centerlayout.setOnTouchListener(new LinearLayout.OnTouchListener(){
  2.             @Override
  3.             public boolean onTouch(View v, MotionEvent m) {
  4.                 if (gestureDetectorc.onTouchEvent(m)) {
  5.                     if(m.getAction()==MotionEvent.ACTION_UP){
  6.                         handler.postDelayed(new Runnable() {
  7.                             @Override
  8.                             public void run() {
  10.                                 hide();
  11.                             }
  12.                         },5000);
  15.                     }
  16.                 }
  18.                 return true;
  19.             }
  20.         });

Declare the runnable in global

  1. Runnable mRunnable = new Runnable() {
  2.     @Override
  3.     public void run() {
  4.         hide();
  5.     }
  6. };

call removeCallbacks before you call postDelay

  1. centerlayout.setOnTouchListener(new LinearLayout.OnTouchListener(){
  2.     @Override
  3.     public boolean onTouch(View v, MotionEvent m) {
  4.         if (gestureDetectorc.onTouchEvent(m)) {
  5.             if(m.getAction()==MotionEvent.ACTION_UP){
  6.                 handler.removeCallbacks(mRunnable);//add this
  7.                 handler.postDelayed(mRunnable, 5000);
  8.             }
  9.         }
  11.         return true;
  12.     }
  13. });
