在加载活动中的所有其他视图后加载YoutubeSupportFragment

Question

我的应用程序中有一个基于片段的活动，它使用Async任务从API读取数据，数据包括电影详细信息以及一些视频ID。我创建了另一个片段，它扩展了YouTubePlayerSupportFragment并显示缩略图并允许播放视频。我正在使用Supportfragmentmanager在主片段中添加基于youtube播放器的片段。

除了在每个其他视图充气后（例如文本视图，图像视图等），youtube缩略图膨胀之外，一切正常，即使我在为内容片段中的任何其他视图设置值之前添加了youtube片段。我还尝试使所有内容不可见，加载所有内容包括youtube片段，然后将可见性设置为true，但即便如此，youtube片段加载大约2,3秒后其他所有内容已经膨胀。反正有没有让youtube播放器片段加载更快？

这是内容片段布局。

我正在使用的Async类的代码在这里（我从上面的父片段的OnCreateView函数调用我的Async类）。

    ImageView itemGenreImage = (ImageView) activity.findViewById(R.id.movie_details_genre_image);
    ImageView itemBackdropImage  = (ImageView) activity.findViewById(R.id.movie_details_backdrop_image);
    ImageView itemPoster = (ImageView) activity.findViewById(R.id.movie_details_poster_thumb);

    FrameLayout thumbnailFrame = (FrameLayout)activity.findViewById(R.id.thumbnail_layout);

    if(movie.isInternetAvailable()== true && movie != null){
        if(movie.getVideos().getVideos() != null && movie.getVideos().getVideos().size() != 0) {

            YoutubeThumbnailFragment youtubeThumbnailFragment = YoutubeThumbnailFragment.newInstance(movie.getVideos().getVideos().get(0).getKey());
            activity.getSupportFragmentManager().beginTransaction().replace(R.id.thumbnail_layout,youtubeThumbnailFragment).commit();
            //thumbnailFrame.setVisibility(View.VISIBLE);
        }
        else{
            String imageSize = utilities.GetBackdropSize();
            com.squareup.picasso.Picasso.with(context).load(context.getString(R.string.tmdb_image_url) + imageSize + movie.getBackdropPath()).into(itemBackdropImage);
            itemBackdropImage.setVisibility(View.VISIBLE);
            thumbnailFrame.setVisibility(View.GONE);
        }
        itemName.setText(movie.getTitle());
        com.squareup.picasso.Picasso.with(context).load(context.getString(R.string.tmdb_image_url) + "w780" + movie.getPosterPath()).fit().into(itemPoster);
