Android 视频播放与进度条同步

首先获取视频播放长度来设置SeekBar的Max，videobBar.setMax(mediaPlayer.getDuration())，然后通过线程实时获取视频已经播放的时间来更新SeekBar，videobBar.setProgress(mediaPlayer.getCurrentPosition())思路就是这样，具体代码如下：

videobBar=(SeekBar)findViewById(R.id.seekBarPlayProgress);

surfaceView = (SurfaceView) findViewById(R.id.player);  surfaceView.getHolder().addCallback(new PlayCallback());  surfaceView.getHolder()    .setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);  surfaceView.getHolder().setFixedSize(surfaceView.getWidth(), surfaceView.getHeight());  mediaPlayer = new MediaPlayer();  mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);  mediaPlayer.setDisplay(surfaceView.getHolder());  try{   mediaPlayer.setDataSource("/sdcard/movie/自娱自乐_1.mp4");   mediaPlayer.prepare();   mediaPlayer.start();   videobBar.setMax(mediaPlayer.getDuration());

   VideoThreed videoThreed=new VideoThreed();   videoThreed.start();  }  catch(Exception e)  {   Toast.makeText(this, "播放错误！", Toast.LENGTH_LONG).show();   }

 

 

//更新UI  Handler myHandler = new Handler()  {    public void handleMessage(Message msg)   {               switch (msg.what)              {                case PROGRESS_CHANGED:                    videobBar.setProgress(mediaPlayer.getCurrentPosition());                 break;           }         }    };

//视频进度条更新 class VideoThreed extends Thread {  public void run()  {    while (!Thread.currentThread().isInterrupted())     {         if(mediaPlayer.getCurrentPosition()==mediaPlayer.getDuration())     {      return;     }                 Message message = new Message();                    message.what =PROGRESS_CHANGED;                    VideoPlayer.this.myHandler.sendMessage(message);                    try                    {                           Thread.sleep(1000);                       }                  catch (InterruptedException e)                    {                           Thread.currentThread().interrupt();                      }                 }     } }
