SurfaceView blank when playing a media player

This is my code, but when I start the media player, it only has sound and the surface is not displayed. Why?

I have no idea about this. You have some code to help me learn this.

videoV = (SurfaceView) findViewById(R.id.SurfaceView1); sh = videoV.getHolder(); File path = Environment.getExternalStorageDirectory(); File file = new File(path, "sample2.mp4"); sh.addCallback(this); mp = new MediaPlayer(); mp.setDataSource(file.getAbsolutePath()); mp.setDisplay(sh); mp.prepare(); mp.start();

Try adding after

 sh.addCallback(this);

this is

 sh.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

In my case, it was helpful.

Have you added a ready listener? I implemented a trigger in this method since it is a trigger that indicates when the video is ready for rendering.

 sh.addCallback(this); mp = new MediaPlayer(); mp.setDataSource(file.getAbsolutePath()); mp.setDisplay(sh); mp.setOnPreparedListener(this); mp.prepare(); public void onPrepared(MediaPlayer arg0) { mp.start(); }

try this code.

resource is the name of the file you want to play, and one.two is the name of the package, the path of which may look like android.resource://package_name/raw/file_name

 VideoView video=(VideoView) findViewById(R.id.videoview); MediaController mediaController = new MediaController(this); mediaController.setAnchorView(video); video.setMediaController(mediaController); //Uri uri = Uri.parse("android.resource://play.vedio/"+R.raw.dobeernotdrugs); video.setKeepScreenOn(true); video.setVideoPath("android.resource://one.two/raw/"+resource); video.start(); video.requestFocus();
