Question

我有一项名为 VideoActivity 的活动。显示 youtubeplayerview ，有一个视频列表。第一次加载视频时。当我点击某个项目时转到另一个活动，然后返回到该活动，它不播放。我可以知道原因吗？

这是代码

public class VideoActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {

public Video video;
private RecyclerView recyclerVideos;
private static final int RECOVERY_DIALOG_REQUEST = 1;
private YouTubePlayerView youTubeView;


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

    recyclerVideos = (RecyclerView) findViewById(R.id.recyclerVideos);

    Intent i = getIntent();
    video = (Video) i.getSerializableExtra("video");

    LinearLayoutManager layoutManager = new LinearLayoutManager(this);
    layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
    recyclerVideos.setLayoutManager(layoutManager);

    new VideoAsyncTask().execute();

 }

@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
public void onInitializationSuccess(YouTubePlayer.Provider provider,
                                    YouTubePlayer player, boolean wasRestored) {

    if (!wasRestored) {
        player.cueVideo(video.Videoid);
        player.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
    }
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == RECOVERY_DIALOG_REQUEST) {
        // Retry initialization if user performed a recovery action
        getYouTubePlayerProvider().initialize(Constants.DEVELOPER_KEY, this);
    }
}

private YouTubePlayer.Provider getYouTubePlayerProvider() {
    return (YouTubePlayerView) findViewById(R.id.youtube_view);
}

private class VideoAsyncTask extends AsyncTask<Void, Void, Video> {

    @Override
    protected void onPreExecute() {

    }

    @Override
    protected Video doInBackground(Void... params) {

        try {
         return   webservice();

        } catch (Exception e1) {
            e1.printStackTrace();
            return null;
        }
    }

    protected void onPostExecute(final Video video) {
        try {
            if (video == null) {
                return;
            }

            VideosAdapter videoAdapter = new VideosAdapter(video.videos,VideoActivity.this);
            recyclerVideos.setAdapter(videoAdapter);
    youTubeView.initialize(Constants.DEVELOPER_KEY, VideoActivity.this);

        } catch (Throwable ignored) {}
    }
}
}

Answer 1

是的。我解决了这个问题。

第1步：将youtubeview添加到linearlayout

第2步：在 onResume 上删除视图，并在返回活动时再次将youtubeview添加到linearlayout

第3步：停止播放YouTube视频

Answer 2

@Override
public void onResume(){
super.onResume();
try {
        if (video == null) {
            return;
        }

       YouTubePlayer.loadVideo(String videoId, int timeMillis);

    } catch (Throwable ignored) {}
}

Answer 3

离开时尝试完成活动，或者在简历上初始化youtubeplay而不是oncreate

@Override
public void onResume(){
    super.onResume();
    new VideoAsyncTask().execute();}

Answer 4

在离开YouTubePlayerView所在的活动/片段之前，先执行以下操作：

youtubePlayer.pause();
youtubePlayer.release();
