我正在尝试将YouTubePlayerFragment嵌入到DialogFragment中。我可以一次启动对话框并在其中显示 YouTubePlayer，但第二次它总是崩溃（无论我做什么）。我认为这是一个生命周期问题，我根本不明白。我正在使用 AndroidAnnotations，问题是 DialogFragment 的视图始终是在由 AndroidAnnotations 生成的 onCreateView 方法中创建的。

有谁知道在这种情况下如何处理 DialogFragment 的生命周期？

这是从 AndroidAnnotations 生成的代码：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    contentView_ = super.onCreateView(inflater, container, savedInstanceState);
    if (contentView_ == null) {
        contentView_ = inflater.inflate(layout.video_fragment, container, false);
    }
    return contentView_;
}

这是我到目前为止所拥有的：

public class VideoFragmentDialog extends DialogFragment implements YouTubePlayer.OnInitializedListener {

    private static final String DEVELOPER_KEY = "secret";
    private String videoUrl;

    @FragmentById(R.id.youTubePlayerFragment)
    YouTubePlayerFragment youTubePlayerFragment;

    @AfterViews
    void initializeYouTubePlayer() {
        youTubePlayerFragment.setRetainInstance(true);
        youTubePlayerFragment.initialize(DEVELOPER_KEY, this);
    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean wasRestored) {
        if (!wasRestored) {
            youTubePlayer.cueVideo(videoUrl);
        }
    }

    @Override
    public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
        //To change body of implemented methods use File | Settings | File Templates.
    }

    public String getVideoUrl() {
        return videoUrl;
    }

    public void setVideoUrl(String videoUrl) {
        this.videoUrl = videoUrl;
    }
}

这是堆栈跟踪：

Caused by: java.lang.IllegalArgumentException: Binary XML file line #10: Duplicate id 0x7f0a0281, tag null, or parent id 0x7f0a0280 with another fragment for com.google.android.youtube.player.YouTubePlayerFragment

    at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:673)

我想这是因为您在片段（嵌套片段）中使用片段而不使用getChildFragment() 在此处查看示例如何执行此操作：嵌套片段
