private VideoView videoView;
private int position = 0;
private MediaController mediaController;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
videoView = (VideoView) findViewById(R.id.videoView);
// Set the media controller buttons
if (mediaController == null) {
mediaController = new MediaController(MainActivity.this);
// Set the videoView that acts as the anchor for the MediaController.
mediaController.setAnchorView(videoView);
// Set MediaController for VideoView
videoView.setMediaController(mediaController);
}
try {
// ID of video file.
String videoUrl="https://www.youtube.com/watch?v=JHdmkP-nfsA";
videoView.setVideoPath(videoUrl);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
videoView.requestFocus();
// When the video file ready for playback.
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mediaPlayer) {
videoView.seekTo(position);
if (position == 0) {
videoView.start();
}
// When video Screen change size.
mediaPlayer.setOnVideoSizeChangedListener(new MediaPlayer.OnVideoSizeChangedListener() {
@Override
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
// Re-Set the videoView that acts as the anchor for the MediaController
mediaController.setAnchorView(videoView);

推荐答案
您不能直接在 VideoView 或 ExoPlayer 中播放 YouTube 视频>，为此，首先您必须下载视频，然后将该视频的语言环境路径设置为方法VideoView.setVideoPath("path")
You can not play a YouTube video directly to the VideoView or ExoPlayer, for that, first you have to download the video then set the locale path of that video to the method VideoView.setVideoPath("path")
如果您只想播放 YouTube 视频，请使用 YouTube Android Player API ，如果您只想播放其他远程视频(.mp4，.ogg，.3gp等)，请使用方法VideoView.setVideoURI("uri").
If you want to play only YouTube videos then use YouTube Android Player API, and if you only want to play other remote videos (.mp4, .ogg, .3gp etc.) then use the method VideoView.setVideoURI("uri").
示例-
String videoUrl = "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4";
try {
// Start the MediaController
MediaController mediacontroller = new MediaController(this);
mediacontroller.setAnchorView(videoview);
// Get the URL from String videoUrl
Uri video = Uri.parse(videoUrl);
videoview.setMediaController(mediacontroller);
videoview.setVideoURI(video);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
videoview.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
videoview.start();
}
});
