VideoView 自定义控制器可见性

Question

我在 videoview 上创建了带有搜索栏的自定义控制器。这些控制器采用线性布局并且工作正常。现在我想像任何其他 android 播放器一样设置此自定义控制器布局的可见性。就像我开始播放视频时它出现 7 秒然后消失，当用户触摸视频时它出现并保持 7 秒然后再次触摸它消失。我的密码是

myMusicView.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {
                // TODO Auto-generated method stub
                try {
                    if (SystemClock.elapsedRealtime() - mLastClickTime < 700){
                        return false;
                    }
                    mLastClickTime = SystemClock.elapsedRealtime();
                    if(isShowing){
                        musicControllBar.setVisibility(View.GONE);

                        isShowing=false;
                    }else{
                        musicControllBar.setVisibility(View.VISIBLE);

                        HideLayout();
                        isShowing=true;
                    }
                } catch (Exception e) {
                    // TODO: handle exception
                }



                return false;
            }
        });

private void HideLayout() {

    try {
        musicControllBar.setVisibility(View.VISIBLE);
         final Handler handler = new Handler();
         handler.postDelayed(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                musicControllBar.setVisibility(View.INVISIBLE);
            }
        }, 7000);
    } catch (Exception e) {
        // TODO: handle exception
    }


    }

Answer 1

我建议使用 CountDownTimer，而不是使用 Handler。

将 class 的全局 CountDownTimer 变量声明为：

CountDownTimer countDownTimer;

对 HideLayout() 函数进行以下更改：

try{
musicControlBar.setVisibility(View.VISIBLE);
countDownTimer = new CountDownTimer(7000, 1000){

    @Override
        public void onTick(long millisUntilFinished) {

            //do nothing
        }

        @Override
        public void onFinish() {

            musicControllBar.setVisibility(View.INVISIBLE);
        }
    }.start();

}catch(Exception e){}

此外，替换您的代码

    if (SystemClock.elapsedRealtime() - mLastClickTime < 700){
                            return false;
}

与

countDownTimer.cancel();

Answer 2

1) First add this code as mention in above answer
private void loadTimer(){
try{
musicControlBar.setVisibility(View.VISIBLE);
countDownTimer = new CountDownTimer(7000, 1000){

    @Override
        public void onTick(long millisUntilFinished) {

            //do nothing
        }

        @Override
        public void onFinish() {
             //this hide your layout when reach at 7 sec
            musicControllBar.setVisibility(View.INVISIBLE);
        }
    }.start();

}catch(Exception e){}
}
2) Try onClickListener at VideoView in onClick() repeat your above code

                    if(isShowing){
                        musicControllBar.setVisibility(View.GONE);

                        isShowing=false;
                    }else{

                        if(countDownTimer!=null){
                          countDownTimer.cancel();
                         loadTimer();//start timer
                         }
                        musicControllBar.setVisibility(View.VISIBLE);

                        isShowing=true;
                    }
