Question

我需要创建 Activity，它将播放来自 URL 的视频。现在，我使用 VideoView 和 MediaController，当这个 activity 创建时，在缓冲视频后它应该播放。它可以工作，但只播放一次，之后媒体控制器可以工作但不播放视频。

这是一段代码：

private ProgressDialog progressDialog;
private VideoView videoView;

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

    progressDialog = new ProgressDialog(this);
    progressDialog.setTitle("Some title");
    progressDialog.setMessage("Buffering...");
    progressDialog.setIndeterminate(false);
    progressDialog.setCancelable(false);
    progressDialog.show();

    videoView = (VideoView) findViewById(R.id.video_view);
    Intent intent = getIntent();
    String url = intent.getStringExtra("extra_url");

    Uri uri = Uri.parse(url);
    videoView.setVideoURI(uri, HeadersMap); // Here I put my headers - I need to do that.

    MediaController mediaController = new MediaController(this);
    mediaController.setAnchorView(videoView);
    videoView.setMediaController(mediaController);
    videoView.requestFocus();
    videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {
            progressDialog.dismiss();
            videoView.start();
        }
    });
}

那么，有什么问题吗？为什么视频不能重复？我将光标设置为在控制器上启动，但没有任何反应。我该如何处理？或者我应该怎么做？

感谢您的解答！

试试这个，

videoView.setOnPreparedListener(new OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        mp.setLooping(true);
    }
});

你也可以用 setOnCompletionListener

videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

    @Override
    public void onCompletion(MediaPlayer mp) {

        videoView.start();  

    }
});

或

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer arg0) {
             mVideoView.start();

        }
    });


    videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        public void onCompletion(MediaPlayer mp) {
                mp.reset();
                videoView.setVideoURI(uri, HeadersMap); 
        }
    });

Android - VideoView MediaController 无法正常工作

Android - VideoView with MediaController don't work correctly
