android - 如何显示来自 URL 的视频

Question

我的应用程序的主选项卡上有一个按钮，试图通过第二个 Activity 从 URL 启动视频

我已经用空白 Activity 进行了测试，并在单击所述按钮时成功显示了“你好”。然后，我删除了“Hello”编辑文本，并按照另一篇类似帖子中的建议将代码添加到 java 文件中。

单击视频按钮时，我收到消息；无法播放此视频，好的”

我已经测试了 youtube 链接，它是一个有效链接。然而 logcat 错误消息包括:

10-07 09:04:36.785: I/MediaPlayer(11397): path is null
10-07 09:04:36.795: D/MediaPlayer(11397): setDataSource IOException happend : 
10-07 09:04:36.795: D/MediaPlayer(11397): 
java.io.FileNotFoundException: No content provider: http://youtu.be/RFrg1xFoxeQ 

我从这里去哪里？

第二个 Activity 的 XML 如下:-

<VideoView
    android:id="@+id/videoView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

</TableLayout>

对应的Java文件

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_serve_motion_up_together);
    String videoPath2 = "http://youtu.be/RFrg1xFoxeQ";
    VideoView videoView1 = (VideoView) findViewById(R.id.videoView1);

    videoView1.setVideoURI(Uri.parse(videoPath2));
    videoView1.setMediaController(new MediaController(this));
    videoView1.setVisibility(1);
    videoView1.bringToFront();
    videoView1.requestFocus();
    videoView1.start();       

}

Answer 1

试试这个:

String LINK = "http://youtu.be/RFrg1xFoxeQ";
setContentView(R.layout.mediaplayer);
VideoView videoView = (VideoView) findViewById(R.id.video);
MediaController mc = new MediaController(this);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
Uri video = Uri.parse(LINK);
videoView.setMediaController(mc);
videoView.setVideoURI(video);
videoView.start();

我不确定它是否有效，但值得一试
