Question

我的应用程序使用YouTube Data API v3播放YouTube视频。我有一个使用VideoPlayerActivity播放Youtube视频的活动YouTubeSupportFragment。在播放第一个视频时，我还允许用户选择要播放的其他视频，它会自己启动VideoPlayerActivity来播放第二个视频。一切顺利。但是，当我按“返回”再次观看第一个视频时，按下YoutubePlayer控制中的“播放”按钮，它会崩溃。
为简单起见，我使用FragmentDemoActivity示例中的YouTubeAndroidPlayerApi。在此活动中，我有一个按钮，当用户点击它时，这将开始FragmentDemoActivity自己播放第二个视频。一切正常。但是当按下Back并单击YoutubePlayer controll上的播放按钮时。它崩溃了。这是代码。

public class FragmentDemoActivity extends YouTubeFailureRecoveryActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.e("FragmentDemoActivity", "onCreate");
        setContentView(R.layout.fragments_demo);

        YouTubePlayerFragment youTubePlayerFragment = (YouTubePlayerFragment) getFragmentManager()
                .findFragmentById(R.id.youtube_fragment);
        youTubePlayerFragment.initialize(DeveloperKey.DEVELOPER_KEY, this);

        (findViewById(R.id.btn_click))
                .setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub
                        Intent intent = new Intent(FragmentDemoActivity.this,
                                FragmentDemoActivity.class);
                        startActivity(intent);
                    }
                });
    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider,
            YouTubePlayer player, boolean wasRestored) {
        Log.e("FragmentDemoActivity", "onInitializationSuccess " + wasRestored);
        if (!wasRestored) {
            player.cueVideo("VvseoF9eASw");
        }
    }

    @Override
    protected YouTubePlayer.Provider getYouTubePlayerProvider() {
        return (YouTubePlayerFragment) getFragmentManager().findFragmentById(
                R.id.youtube_fragment);
    }

}

这是logcat

任何帮助将不胜感激。提前谢谢。

Answer 1

就这样做

创建

private YouTubePlayer youTubePlayer;

然后初始化youTubePlayer = player;

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
    Log.e("FragmentDemoActivity", "onInitializationSuccess " + wasRestored);
    if (!wasRestored) {
        player.cueVideo("VvseoF9eASw");
    }
    youTubePlayer = player;
}

并覆盖onResume()

@Override
protected void onResume() {
    super.onResume();
    if (youTubePlayer !=null) {
        youTubePlayer.cueVideo("VvseoF9eASw");
}

P.S。

如果您想从上一刻开始播放视频（暂停），请在VideoPlayerActivity mPlayer.getCurrentTimeMillis()中获取暂停时间并发送至FragmentDemoActivity

之后将onResume()中的FragmentDemoActivity更改为

@Override
protected void onResume() {
    super.onResume();
    if (youTubePlayer !=null) {
        youTubePlayer.cueVideo("VvseoF9eASw", time_from_video_player_activity);
}

使用YouTube Data API时崩溃
