如何将 MediaController 放入 TextureView

Question

我正在尝试将媒体控制器放入我的纹理视图中，但我总是遇到错误

E/MediaPlayer﹕ Should have subtitle controller already set

这是我的代码

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.texture_video);

    textureView = (TextureView) findViewById(R.id.textureView);
    listView = (ListView) findViewById(R.id.list);

  .
  .
  .

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, android.R.id.text1, values);


    listView.setAdapter(adapter);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {

            if (position == 0) {
                onDestroy();
                FILE_NAME = "test1.mp4";
                textureView.setSurfaceTextureListener(VideoAssetActivity.this);
                onSurfaceTextureAvailable(textureView.getSurfaceTexture(), view.getWidth(), view.getHeight());
            } else if (position == 1) {
                onDestroy();
                FILE_NAME = "test2.mp4";
                textureView.setSurfaceTextureListener(VideoAssetActivity.this);
                onSurfaceTextureAvailable(textureView.getSurfaceTexture(), view.getWidth(), view.getHeight());
            } else if (position == 2) {
                onDestroy();
                FILE_NAME = "test3.mp4";
                textureView.setSurfaceTextureListener(VideoAssetActivity.this);
                onSurfaceTextureAvailable(textureView.getSurfaceTexture(), view.getWidth(), view.getHeight());
            } else if (position == 3) {
                onDestroy();
                FILE_NAME = "test4.mp4";
                textureView.setSurfaceTextureListener(VideoAssetActivity.this);
                onSurfaceTextureAvailable(textureView.getSurfaceTexture(), view.getWidth(), view.getHeight());
            }
        }

    });
    textureView.setSurfaceTextureListener(this);

}

@Override
protected void onDestroy() {
    super.onDestroy();
    if (mMediaPlayer != null) {
        mMediaPlayer.stop();
        mMediaPlayer.release();
        mMediaPlayer = null;
    }
}

@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int i, int i2) {
    Surface surface = new Surface(surfaceTexture);

    try {
        AssetFileDescriptor afd = getAssets().openFd(FILE_NAME);
        mMediaPlayer = new MediaPlayer();
        mMediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
        mMediaPlayer.setSurface(surface);
        mMediaPlayer.setLooping(true);
        mMediaPlayer.prepareAsync();

        onSurfaceTextureUpdated(surfaceTexture);

        mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mediaPlayer) {
                // set up media controller
                videoController = new MediaController(VideoAssetActivity.this);
                videoController.setAnchorView(textureView);
                videoController.setPadding(0, 0, 0, 0);

                    mediaPlayer.start();

            }
        });

    } catch (IllegalArgumentException e) {
        Log.d(TAG, e.getMessage());
    } catch (SecurityException e) {
        Log.d(TAG, e.getMessage());
    } catch (IllegalStateException e) {
        Log.d(TAG, e.getMessage());
    } catch (IOException e) {
        Log.d(TAG, e.getMessage());
    }


}

我的问题是我已经设置了控制器，但即使我播放其他 mp4 也没有显示。我已经搜索了解决方案，但我只看到了音频文件。谁能帮我？非常感谢..

Answer 1

实施MediaController.MediaPlayerControl
覆盖需要的函数

通过此代码显示控制器：

MediaController videoController = new MediaController(getActivity());
videoController.setMediaPlayer(this);//your activity which implemented MediaPlayerControl
videoController.setAnchorView(mTextureView);
videoController.setEnabled(true);
videoController.show();

玩得开心！
