android - 如何从此代码调用 YouTube Intent ？

Question

如何更改此 Android 代码以调用 YouTube Intent ？
我想让它在我的应用程序中启动 YouTube 播放器。我认为被调用的播放器与 YouTube 流媒体视频不兼容。

这是下面的代码 fragment :

@Override
        protected void onPostExecute(DetailsOverviewRow row) {
            /* 1st row: DetailsOverviewRow */

              /* action setting*/
            SparseArrayObjectAdapter sparseArrayObjectAdapter = new SparseArrayObjectAdapter();
            sparseArrayObjectAdapter.set(0, new Action(ACTION_PLAY_VIDEO, "Play Video"));
            sparseArrayObjectAdapter.set(1, new Action(1, "Action 2", "label"));
            sparseArrayObjectAdapter.set(2, new Action(2, "Action 3", "label"));

            row.setActionsAdapter(sparseArrayObjectAdapter);

            mFwdorPresenter.setOnActionClickedListener(new OnActionClickedListener() {
                @Override
                public void onActionClicked(Action action) {
                    if (action.getId() == ACTION_PLAY_VIDEO) {
                        Intent intent = new Intent(getActivity(), PlaybackOverlayActivity.class);
                        intent.putExtra(getResources().getString(R.string.movie), mSelectedMovie);
                        intent.putExtra(getResources().getString(R.string.should_start), true);
                        startActivity(intent);
                    }
                }
            });

更新:这是 PlayerOverlay Activity 代码:

public class PlaybackOverlayActivity extends Activity {

    private static final String TAG = PlaybackOverlayActivity.class.getSimpleName();

    private VideoView mVideoView;

    private LeanbackPlaybackState mPlaybackState = LeanbackPlaybackState.IDLE;

    private int mPosition = 0;
    private long mStartTimeMillis;
    private long mDuration = -1;

    /*
     * List of various states that we can be in
     */
    public enum LeanbackPlaybackState {
        PLAYING, PAUSED, IDLE
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_playback_overlay);

        loadViews();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        stopPlayback();
        mVideoView.suspend();
        mVideoView.setVideoURI(null);
    }

    private void loadViews() {
        mVideoView = (VideoView) findViewById(R.id.videoView);
        mVideoView.setFocusable(false);
        mVideoView.setFocusableInTouchMode(false);

        Movie movie = (Movie) getIntent().getSerializableExtra(DetailsActivity.MOVIE);
        setVideoPath(movie.getVideoUrl());

    }

    public void setVideoPath(String videoUrl) {
        setPosition(0);
        mVideoView.setVideoPath(videoUrl);
        mStartTimeMillis = 0;
        mDuration = Utils.getDuration(videoUrl);
    }

    private void stopPlayback() {
        if (mVideoView != null) {
            mVideoView.stopPlayback();
        }
    }

    private void setPosition(int position) {
        if (position > mDuration) {
            mPosition = (int) mDuration;
        } else if (position < 0) {
            mPosition = 0;
            mStartTimeMillis = System.currentTimeMillis();
        } else {
            mPosition = position;
        }
        mStartTimeMillis = System.currentTimeMillis();
        Log.d(TAG, "position set to " + mPosition);
    }

    public int getPosition() {
        return mPosition;
    }

    public void setPlaybackState(LeanbackPlaybackState playbackState) {
        this.mPlaybackState = playbackState;
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_playback_overlay, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    public void playPause(boolean doPlay) {
        if (mPlaybackState == LeanbackPlaybackState.IDLE) {
            /* Callbacks for mVideoView */
            setupCallbacks();
        }

        if (doPlay && mPlaybackState != LeanbackPlaybackState.PLAYING) {
            mPlaybackState = LeanbackPlaybackState.PLAYING;
            if (mPosition > 0) {
                mVideoView.seekTo(mPosition);
            }
            mVideoView.start();
            mStartTimeMillis = System.currentTimeMillis();
        } else {
            mPlaybackState = LeanbackPlaybackState.PAUSED;
            int timeElapsedSinceStart = (int) (System.currentTimeMillis() - mStartTimeMillis);
            setPosition(mPosition + timeElapsedSinceStart);
            mVideoView.pause();
        }
    }

    public void fastForward() {
        if (mDuration != -1) {
            // Fast forward 10 seconds.
            setPosition(mVideoView.getCurrentPosition() + (10 * 1000));
            mVideoView.seekTo(mPosition);
        }
    }

    public void rewind() {

        });

        mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override

使用 youtube api Android

-下载Youtube API Client

-registering的说明|您的应用程序说明如何在 Google Developers Console 中注册您的应用程序并获取 Android API key ，您将需要使用该 API。

- 代码示例

public class PlayerVideo extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {

private static final int RECOVERY_DIALOG_REQUEST = 1;
public boolean FLAG_FULL=false;


public String DEV_KEY= "YOUR DEVLOPPER KEY";


    int key;
private YouTubePlayerView youTubePlayerView;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_trailler_play);
    Bundle extras=getIntent().getExtras();
    if(extras!=null){

        key=extras.getInt("ID");

    }

    youTubePlayerView=(YouTubePlayerView)findViewById(R.id.youtube_view);



    youTubePlayerView.initialize(Config.DEVELOPER_KEY,this);
    youTubePlayerView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            FLAG_FULL=true;

        }
    });

}




@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
    if (!wasRestored) {
        player.setFullscreen(FLAG_FULL);
        // loadVideo() will auto play video
        // Use cueVideo() method, if you don't want to play it automatically

        player.loadVideo(getIntent().getStringExtra("ID"));


        // Hiding player controls
        player.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
    }
    //player.cueVideo(getIntent().getStringExtra("ID"));
}

@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult errorReason) {
    if (errorReason.isUserRecoverableError()) {
        errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
    } else {
        String errorMessage = String.format(
                getString(R.string.error_player), errorReason.toString());
        Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode==RECOVERY_DIALOG_REQUEST){
        getYouTubePlayerProvider().initialize(Config.DEVELOPER_KEY, this);
    }
}
private YouTubePlayer.Provider getYouTubePlayerProvider() {
    return (YouTubePlayerView) findViewById(R.id.youtube_view);
}

}

还有一个 Intent 的例子

Intent i=new Intent(getActivity().getApplication(), TraillerPlay.class);
                    i.putExtra("ID", "YOUTUBE_VIDEO_ID");
                    startActivity(i);
