我在youtube视频的播放列表中遇到问题.让我解释一下，我有一个片段，放在listview上.在该列表中，每个项目都有单独的子视图.我被放置在< com.google.android.youtube.player.YouTubeThumbnailView> 标记中，并且还尝试放置Fragment.在这两种情况下，我都会遇到二进制膨胀"异常.请告诉我任何解决我问题的方法.

I am facing problem with show and play list of youtube videos. Let me explain, I have a fragment and placed on listview. In that list have separate child view for each item. I was placed <com.google.android.youtube.player.YouTubeThumbnailView> tag and also try to place Fragment. In both cases I am getting Binary Inflated exception. Please tell me any solution for my problem.

/YouTubePlayerFragment#Overview"rel =" nofollow>文档，

of documentation,

请注意，在播放视频时，此视图的最小尺寸为200x110 dp.如果缩小视图，视频将自动停止播放.另外，在播放视频时，不允许将此片段的视图与其他视图重叠.

Note that while videos are playing, this View has a minimum size of 200x110 dp. If you make the view any smaller, videos will automatically stop playing. Also, it is not permitted to overlay this fragment's view with other views while a video is playing.
