Question

我正试图将youtube视频播放到android videoView但它显示的对话框无法播放视频使用Android 4.4及更高版本我得到了一些例子，但它使用intent.my的要求是将youtube视频播放到我的应用布局

public class YoutubeActivity extends AppCompatActivity {
    private VideoView videoView;
    private MediaController mController;
    private Uri uriYouTube;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_youtube);
        videoView = (VideoView) findViewById(R.id.videoView1);
        mController = new MediaController(this);
        videoView.setMediaController(mController);
        videoView.requestFocus();

 /*Uri uri = Uri.parse("android.resource://" + this.getPackageName() + "/"
 + R.raw.sample);
 videoView.setVideoURI(uri);
 videoView.start();*/

        if (savedInstanceState != null) {
            int loc = savedInstanceState.getInt("Loc");
            Log.i("Loaction: ", loc + "");
            uriYouTube = Uri.parse(savedInstanceState.getString("url"));
            videoView.setVideoURI(uriYouTube);
            videoView.seekTo(loc);
            videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    Log.v("onPrepared", "ok");
                    mp.start();
                }
            });
        } else {
            RTSPUrlTask truitonTask = new RTSPUrlTask();
            truitonTask.execute("http://www.youtube.com/watch?v=2zNSgSzhBfM");
        }

    }

    void startPlaying(String url) {
        uriYouTube = Uri.parse(url);
        videoView.setVideoURI(uriYouTube);
        videoView.start();
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putInt("Loc", videoView.getCurrentPosition());
        outState.putString("url", uriYouTube.toString());
    }

   /* @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.video_view, menu);
        return true;
    }*/

    private class RTSPUrlTask extends AsyncTask<String, Void, String> {
        @Override
        protected String doInBackground(String... urls) {
            String response = getRTSPVideoUrl(urls[0]);
            return response;
        }

                            String f = maps.get("yt:format");
                            if (maps.containsKey("url"))
                                cursor = maps.get("url");
                            if (f.equals("1"))
                                return cursor;
                        }
                    }
                }
                return cursor;
            } catch (Exception ex) {
                return urlYoutube;
            }
        }

        public String extractYoutubeId(String url) throws MalformedURLException {
            String query = new URL(url).getQuery();
            String[] param = query.split("&");
            String id = null;
            for (String row : param) {

                if (param1[0].equals("v")) {
                    id = param1[1];

            }
            return id;
        }

    }

你可以给我一个解决方案。
