问题描述

寻找了几个小时后，我问这个，任何相关答案欢迎。

After searching for many hours , i am asking this, any related answers are welcomed . .

我有我的R.raw文件夹中的视频和我玩这两个videoview同时持续时间相同的，这里是我的code，

I'm having a video in my R.raw folder and i am playing it in two videoview of same duration simultaneously , here is my code ,

     sb = (SeekBar)findViewById(R.id.control_seekbar);

     mVideoView1 = (VideoView) findViewById(R.id.surface_view1);
     mVideoView1.setVideoPath("android.resource://" + getPackageName() +"/"+R.raw.play1);              
     mVideoView1.start();

     mVideoView2 = (VideoView) findViewById(R.id.surface_view2);
     mVideoView2.setVideoPath("android.resource://" + getPackageName() +"/"+R.raw.play2);              
     mVideoView2.start();

     v1 = mVideoView1.getDuration();
     v2 = mVideoView2.getDuration();

     mVideoView1.setOnPreparedListener(new OnPreparedListener() 
     {
        @Override
        public void onPrepared(MediaPlayer arg0) 
        {
            sb.setMax(mVideoView1.getDuration()+3);
            sb.postDelayed(onEverySecond, 60);
        }
     });

     sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener() 
     {  
        @Override
        public void onStopTrackingTouch(SeekBar seekBar) 
        {
            mVideoView1.seekTo(sb.getProgress());
            mVideoView2.seekTo(sb.getProgress());
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) 
        {
            mVideoView1.seekTo(sb.getProgress());
            mVideoView2.seekTo(sb.getProgress());
        }

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) 
        {
            mVideoView1.seekTo(progress);
            mVideoView2.seekTo(progress);
        }

    });

   }

   private Runnable onEverySecond=new Runnable() 
   {
        @Override
        public void run() 
        {
            if(sb != null) 
            {
                sb.setProgress(mVideoView1.getCurrentPosition());
            }

            if(mVideoView1.isPlaying()) 
            {
                sb.postDelayed(onEverySecond, 1000);
                if(mVideoView1.getDuration() <= sb.getProgress())
                {
                    mVideoView1.seekTo(0);
                    mVideoView2.seekTo(0);
                }
            }
        }
    };

和我可以拖动搜索栏到新的位置，它是由新位置正常播放。

and i could drag the seekbar to the new position and it is playing from the new position correctly .

但我不想开始播放视频。它应该是暂停（），并为我拖累了搜索栏，在videoview应该更新到相应的位置。

But i dont want to play the video initially . It should be in pause() and as i drag the seekbar, the videoview should update to the respective position .

当我改变mVideoView.start（）暂停（），我只能看到黑屏，并在videoview搜索栏位置变化没有更新。

When i change the mVideoView.start() to pause() , i could see only a blank black screen and no update for the seekbar position change in the videoview .

在什么样的方式我可以实现它。

in what way i could achieve it .

推荐答案

您必须把媒体控制器在videoview。

You have to put a media controller in your videoview.

MediaController mediaController = new MediaController(context);
myVideoView.setMediaController(mediaController).

现在当你在你的视频点击播放，暂停按钮将显示。

Now when you click on your video the play, pause buttons will show.
