[移动开发]android MediaPlayer m3u8 播放

项目中用到在播放服务上的m3u8的视频，android自带的MediaPlayer就支持，因此写个demo记录下
布局文件activity_main.xml

public class MainActivity extends AppCompatActivity {
    private String url = "http://121.132.117.216/hls/a.m3u8";  //换成你自己视频地址
    private SurfaceHolder surfaceHolder;

    @Override

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_my_media_player);

        surfaceView = (SurfaceView)findViewById(R.id.surfaceView);
        mediaPlayer = new MediaPlayer();
        try {

            surfaceHolder =surfaceView.getHolder();

                @Override
                public void surfaceCreated(@NonNull SurfaceHolder surfaceHolder) {
                    mediaPlayer.setDisplay(surfaceHolder);
                }
                @Override
                public void surfaceChanged(@NonNull SurfaceHolder surfaceHolder, int i, int i1, int i2) {
                }
                @Override
                public void surfaceDestroyed(@NonNull SurfaceHolder surfaceHolder) {
                }
            });
            mediaPlayer.prepare();
            mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    mediaPlayer.start();
                    mediaPlayer.setLooping(true);
                }
            });
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

不过在模拟器上播放时只有声音没有画面，在真机上有声音和画面
