示例代码：

如何在一个活动中播放两个视频

public class Two_videos extends Activity 
{
VideoView video1, video2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.two_video);

VideoView video1= (VideoView) findViewById(R.id.video1);
              video1.setVideoPath("/mnt/sdcard/Movies/com.bnb.giggle/IMG_20130415184609.mp4");
            video1.start();

VideoView video2= (VideoView) findViewById(R.id.video2);
        video2.setVideoPath("/mnt/sdcard/Movies/com.bnb.giggle/IMG_20130415184608.mp4");
        video2.start();
   }
}

不能同时播放两个视频。

Answer 1

播放多个视频取决于硬件，但如果您的设备仅支持一个媒体播放器实例，则必须调用您的VideoView.stopPlayBack（）以在另一个视频视频中播放视频。您可以使用resume（）方法在第一视频视频中恢复视频，但是从第二视频停止播放后。

Answer 2

您的设备应支持播放多个视频以及需要高端设备的视频（高清视频）质量，否则会出错。

我尝试了this代码，它适用于所有nexus设备。

Answer 3

根据this answer，可以同时播放多个视频，但这取决于设备及其硬件。 Android版似乎并不重要。我建议你阅读他的评论和代码以便更好地理解。

Answer 4

见下面的代码，这里在一个活动的不同视频视图中播放4个视频

main_activity.xml

Answer 5

以下是在一个活动中显示多个视频的完整答案。在所有设备中工作。我使用Surfaceview和Textureview播放视频。

的活动：

 public class ReactionViewActivity extends AppCompatActivity   {
    private static final String TAG = ReactionViewActivity.class.getSimpleName();

    private String mainVideo = "";
    private ProgressBar progress_bar;

    private SurfaceView mSurfaceView;
    private TextureView mTextureView;
    private MediaPlayer mMediaPlayer, mMediaPlayer1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_reaction_view);
        initView();
    }

    private void initView() {
        progress_bar = findViewById(R.id.progress_bar);
        mSurfaceView = findViewById(R.id.surface_view);
        mTextureView = findViewById(R.id.textureView);

        textureParams = (FrameLayout.LayoutParams) mTextureView.getLayoutParams();
        surfaceParams = (FrameLayout.LayoutParams) mSurfaceView.getLayoutParams();

        final String video = getIntent().getStringExtra("video");
        mTextureView.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {
            @Override
            public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int i, int i1) {
                Surface surface = new Surface(surfaceTexture);
                try {
                    mMediaPlayer1 = new MediaPlayer();
                    mMediaPlayer1.setDataSource(video);
                    mMediaPlayer1.setSurface(surface);
                    mMediaPlayer1.setLooping(true);
                    mMediaPlayer1.prepareAsync();

                    // Play video when the media source is ready for playback.
                    mMediaPlayer1.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                        @Override
                        public void onPrepared(MediaPlayer mediaPlayer) {
                            progress_bar.setVisibility(View.GONE);
                            mediaPlayer.start();
                        }
                    });
                    mMediaPlayer1.setAudioStreamType(AudioManager.STREAM_MUSIC);
                } 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());
                }
            }

            @Override
            public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int i, int i1) {

            }

            @Override
            public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) {
                return false;
            }

            @Override
            public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) {

            }
        });

        if (Objects.requireNonNull(getIntent().getExtras()).containsKey("mainVideo")) {
            mainVideo = getIntent().getStringExtra("mainVideo");
            mSurfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {
                @Override
                public void surfaceCreated(SurfaceHolder surfaceHolder) {
                    mMediaPlayer = new MediaPlayer();
                    mMediaPlayer.setDisplay(surfaceHolder);
                    try {
                        mMediaPlayer.setDataSource(mainVideo);
                        mMediaPlayer.setLooping(true);
                        mMediaPlayer.prepare();
                        mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                            @Override
                            public void onPrepared(MediaPlayer mediaPlayer) {
                                mMediaPlayer.start();
                            }
                        });
                        mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {

                }

                @Override
                public void surfaceDestroyed(SurfaceHolder surfaceHolder) {

                }
            });
        }

    }

    @Override
    public void onBackPressed() {
        releaseMediaPlayer();
        finish();
    }


    @Override
    protected void onDestroy() {
        super.onDestroy();
        releaseMediaPlayer();
    }

    private void releaseMediaPlayer() {
        if (mMediaPlayer != null) {
            mMediaPlayer.release();
            mMediaPlayer = null;
        }

        if (mMediaPlayer1 != null) {
