我在为在线视频创建一个媒体播放器,但是当我尝试运行它时,显示了表面已经发布的错误.这是我的编码：
public class VideoSample1 extends Activity implements Callback,OnPreparedListener,OnCompletionListener,OnClickListener,OnSeekCompleteListener,android.view.SurfaceHolder.Callback
{
public String video_path = "My video URL";
private SurfaceView surfaceViewFrame;
private MediaPlayer player;
private SurfaceHolder holder;
private Bundle extras;
private static final String TAG = "log_tag";
private boolean b =false;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.customvideoview);
extras = getIntent().getExtras();
surfaceViewFrame = (SurfaceView) findViewById(R.id.surfaceViewFrame);
surfaceViewFrame.setonClickListener(this);
surfaceViewFrame.setClickable(false);
holder = surfaceViewFrame.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
player = new MediaPlayer();
player.setonPreparedListener(this);
player.setonCompletionListener(this);
player.setonSeekCompleteListener(this);
player.setScreenOnWhilePlaying(true);
player.setdisplay(holder);
}
@Override
protected void onDestroy()
{
super.onDestroy();
player.stop();
player.release();
player = null;
Toast.makeText(VideoSample1.this,"back",Toast.LENGTH_SHORT).show();
finish();
}
private void playVideo()
{
new Thread(new Runnable()
{
public void run()
{
try
{
player.setDataSource(VideoSample1.this,Uri.parse(extras.getString("Video URL")));
player.prepareAsync();
}
catch (IllegalArgumentException e)
{
Log.d("admin","Error while playing video");
e.printstacktrace();
Log.i(TAG,"tag"+ e.getMessage());
}
catch (IllegalStateException e)
{
Log.d("admin","Error1 while playing video");
e.printstacktrace();
Log.i(TAG,"tag"+e.getMessage());
}
catch (IOException e)
{
e.printstacktrace();
Log.d("admin","Error while playing video.Please,check your network connection");
Log.i(TAG,"tag"+e.getLocalizedMessage());
}
}
}).start();
}
public void surfaceChanged(SurfaceHolder holder,int format,int width,int height)
{
}
public void surfaceCreated(SurfaceHolder holder)
{
playVideo();
}
public void surfaceDestroyed(SurfaceHolder holder)
{
}
public void onPrepared(MediaPlayer mp)
{
if (!player.isPlaying())
{
b = true;
player.start();
}
}
public void onCompletion(MediaPlayer mp)
{
mp.stop();
finish();
}
public void onSeekComplete(MediaPlayer mp)
{
}
@Override
public void invalidateDrawable(Drawable who)
{
}
@Override
public void scheduleDrawable(Drawable who,Runnable what,long when)

@Override
public void unscheduleDrawable(Drawable who,Runnable what)
{
// Todo Auto-generated method stub
}
@Override

}
}
我引用了this和其他堆栈溢出站点,但没有与我一起工作:-(.错误在setdisplay(持有者)附近.
这里是我的Logcat消息：
