android - VideoView 抛出 IllegalStateException

Question

我的应用程序中有一个视频 View ，可以播放我的扩展文件中的视频。这是代码:

private VideoView _vv;
    private static final Uri CONTENT_URI = Uri.parse("content://--PACKAGENAMEHIDDENFORSECURITY--.EHZipUriProvider");
    private static final String VIDEO_NAME  = "b1.mp4";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_video_player);
    _vv = (VideoView) findViewById(R.id.vv);

    startVideoPlayback();
}

private void startVideoPlayback()
{
    MediaController mediaController = new MediaController(this);
    mediaController.setAnchorView(_vv);

    _vv.setMediaController(mediaController);
    _vv.setVideoURI(Uri.parse(CONTENT_URI + "/" + VIDEO_NAME));
    _vv.start();
}

堆栈跟踪:

java.lang.IllegalStateException

            at android.widget.VideoView.openVideo(VideoView.java:335)

            at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:5725)
            ...

我不知道为什么会这样。谁能帮忙？

我的布局只是一个视频 View 。

试试这个

try {


        mediaController = new MediaController(this);
        mediaController.setAnchorView(videoView);

        Uri video = Uri.parse(url);
        videoView.setMediaController(mediaController);
        videoView.setVideoURI(video);

        videoView.setOnErrorListener(new OnErrorListener() {

            @Override
            public boolean onError(MediaPlayer mp, int what, int extra) {
                return false;
            }
        });

        videoView.setOnPreparedListener(new OnPreparedListener() {
            public void onPrepared(MediaPlayer mp) {
                videoView.start();
            }
        });
        videoView.setOnCompletionListener(new OnCompletionListener() {

            @Override
            public void onCompletion(MediaPlayer mp) {

            }
        });

    } catch (Exception e) {
    }
