我正在创建一个应用程序HonyComb，我必须在其中显示视频和视频列表。为此，我创建了两个片段，一个用于显示视频，另一个用于 videoList。当用户单击视频列表时，该视频应该开始videoview在其他片段中播放。
我创建了expandablelist用于显示 videoList 的自定义（因为我的视频被归类为组）。我必须显示视频图像、标题和描述，我已经为其创建了一个imageview和两个布局textview。我能够显示视频列表。现在我被困在两点：
- 单击视频列表时，我无法播放视频。
onChildCLick()没有被调用，但onTouch()能够onGroupClick()被调用。 - 我想在用户点击时全屏播放视频
VideoView。我不知道如何实现。
请帮我..
片段布局.xml
