It has something to do with your link and content. Try the following two links:
它与您的链接和内容有关。尝试以下两个链接：
String path="http://www.ted.com/talks/download/video/8584/talk/761";
String path1="http://commonsware.com/misc/test2.3gp";
Uri uri=Uri.parse(path1);
VideoView video=(VideoView)findViewById(R.id.VideoView01);
video.setVideoURI(uri);
video.start();
Start with "path1", it is a small light weight video stream and then try the "path", it is a higher resolution than "path1", a perfect high resolution for the mobile phone.
从“path1”开始，它是一个小的轻量级视频流，然后尝试“path”，它比“path1”更高的分辨率，完美的手机高分辨率。

mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
Uri video = Uri.parse(LINK);
videoView.setMediaController(mc);
videoView.setVideoURI(video);

You can do it using FullscreenVideoViewclass. Its a small library project. It's video progress dialog is build in. it's gradle is :
您可以使用FullscreenVideoView类来完成。它是一个小型图书馆项目。它的视频进度对话框是内置的。它的 gradle 是：
compile 'com.github.rtoshiro.fullscreenvideoview:fullscreenvideoview:1.1.0'
your VideoView xml is like this
你的 VideoView xml 是这样的
<com.github.rtoshiro.view.video.FullscreenVideoLayout
android:id="@+id/videoview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
In your activity , initialize it using this way:
在您的活动中，使用以下方式对其进行初始化：
FullscreenVideoLayout videoLayout;
videoLayout = (FullscreenVideoLayout) findViewById(R.id.videoview);
videoLayout.setActivity(this);
Uri videoUri = Uri.parse("YOUR_VIDEO_URL");
try {
videoLayout.setVideoURI(videoUri);
} catch (IOException e) {
e.printStackTrace();
}
That's it. Happy coding :)
就是这样。快乐编码:)

mVideoView.setZOrderOnTop(true); //Very important line, add it to Your code
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
// here write another part of code, which provides starting the video

Check whether your phone supports the video format or not.Even I had the problem when playing a 3gp file but it played a mp4 file perfectly.
检查您的手机是否支持视频格式。即使我在播放3gp文件时也有问题，但它完美播放了mp4文件。
