Question

我正在为HonyComb创建一个应用程序，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。当用户点击视频列表时，该视频应该开始在其他片段的videoview中播放。

我创建了自定义expandablelist来显示videoList（我的视频被分类为组）。我必须显示已使用imageview和两个textview创建布局的视频图像，标题和说明。我可以显示视频列表。现在我被困在两点：

点击视频列表后，我无法播放视频。未调用onChildCLick()，但可以调用onTouch()和onGroupClick()。
当用户点击VideoView时，我想全屏播放视频。我不知道如何实现它。

请帮帮我..

请从ListFragment（正确方式）扩展VideoListFragment，您可以在其中直接设置适配器，可以收听listitemclick事件等，这将有助于解决您的问题。

为此，您可以浏览this教程。

然后解决你的第二个问题（点击时的全屏视图）：

当用户触摸视频部分两次（点击）时（你可以在ontouchlistener和计时器的帮助下检查是否发生了连续触摸），拨打另一个活动，在视图部分，全屏设计视图。因此，当用户点击回来时，它将返回到片段活动。

如何使用两个片段实现视频和视频列表
