樣子大概是這樣的：

2.textureView設定監聽器，然後在監聽器裡做相應的處理即可。

textureView.setSurfaceTextureListener(surfaceTextureListener);
private SurfaceTextureListener surfaceTextureListener = new SurfaceTextureListener() {

        @Override
        public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
            if (mMediaPlayer == null){
                return;
            }
            mMediaPlayer.setSurface(new Surface(surface));
        }

        @Override
        public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {

        }

        @Override
        public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
            if (mMediaPlayer != null){
                mMediaPlayer.release();
                mMediaPlayer = null;
            }
            return false;
        }

        @Override
        public void onSurfaceTextureUpdated(SurfaceTexture surface) {

        }
    };
 

在onSurfaceTextureAvailable（）方法中可以獲取到suface物件，這就是mediaplayer所需的播放控制元件。下面就是media player的相關操作了。

private void initMediaPlayer() {
        AudioManager mAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
        int mVolumn = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
        if (mMediaPlayer == null) {
            mMediaPlayer = new MediaPlayer();
            mMediaPlayer.setOnPreparedListener(new OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {

                }
            });
            mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {
                @Override
                public void onCompletion(MediaPlayer mp) {
                    Toast.makeText(MainActivity.this,"播放完成！繼續從頭播放", Toast.LENGTH_SHORT).show();
                    restart();
                }
            });
            mMediaPlayer.setOnErrorListener(new OnErrorListener() {
                @Override
                public boolean onError(MediaPlayer mp, int what, int extra) {
                    return false;
                }
            });
            mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mMediaPlayer.setOnSeekCompleteListener(new OnSeekCompleteListener() {
                @Override
                public void onSeekComplete(MediaPlayer mp) {

                }
            });
            mMediaPlayer.setVolume(mVolumn, mVolumn);

        } else {
            mMediaPlayer.reset();
        }
    }

private void play() {
        if (mMediaPlayer == null){
            return;
        }
        if (mMediaPlayer.isPlaying()){
            return;
        }
        try {
            mMediaPlayer.reset();
            mMediaPlayer.setDataSource(this, Uri.parse(path));
            mMediaPlayer.prepare();
            mMediaPlayer.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
 

3.textureView還可以做一些view相關的功能，如平移，縮放，透明度，旋轉等等。

private void initTextureView() {
        textureView.setAlpha(0.8f);
        textureView.setScaleX(1);
        textureView.setScaleY(0.8f);
        textureView.setRotation(90);
    }

這裡只是簡單的操作。。。
