如何从URL

我有试图通过如何从URL

我有一个空白活性的研究，并成功地显示“次活动从URL启动视频我的应用程序的主选项卡上的按钮显示视频你好'当所述按钮被点击时。然后，我删除了'Hello'editext并将代码添加到java文件中，如另一个类似帖子中的建议。

当点击视频BTN，我得到的消息;无法播放该视频，确定”

我已经测试了Youtube链接是一个有效的链接。然而，logcat错误信息包括：

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

我该从哪里出发？

第二活动的XML如下： - 

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

</TableLayout>

相应的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();  

}

logcat的

您不能简单地将YouTube网址传送到MediaPlayer。毕竟这是一些网页的链接。 Android正在尝试处理该问题，但该URL（模式，域等）没有ContentProvider。如果您想在应用程序中播放YouTube视频，您应该查看YouTube SDK for Android。

最好的问候， Darek

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();

我不知道它会工作，但值得一试
