如何使用两个片段实现视频和视频列表

我正在为HonyComb创建一个应用程序，其中我必须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.When用户单击视频列表时，该视频应该在其他片段中的videoview开始播放。如何使用两个片段实现视频和视频列表

我已经创建了自定义expandablelist用于显示videoList（因为我的视频分为组）。我必须显示视频图像，标题和说明，我已使用imageview和两个textview创建了布局。我可以显示视频列表。现在我被困在两点：

当我点击视频列表时，我无法播放视频。 onChildCLick()没有被调用，但onTouch()和onGroupClick()能够被调用。
我想在用户点击VideoView时全屏播放视频。我不知道如何实现。

请帮助我..

您能否共享一段代码，我们可以帮助您 –

@EldhoseMBabu我已经添加了代码.. – Nishant

请从ListFragment（有道），在那里你可以直接setadapter，可以听listitemclick延长VideoListFragment事件等，这将有助于解决您的问题。

为此，您可以通过this教程。

然后解决您的第二个问题（攻丝时全屏视图）：

当用户触摸视频部分的两倍（抽头）（你可以用ontouchlistener的帮助和一个计时器得到这个检查是否连续触摸发生），打电话给视图部分中的另一个活动，设计全屏视图。所以当用户点击后，它会回到片段活动。

感谢您的快速响应......我在我的videoList中使用'ExpandableListView'我无法扩展'ListFragment'并且不支持扩展'ExpandableListFragment'.I将尝试你的videoview逻辑。 – Nishant

你可以在我的代码中看到为什么'onChildClickListener（）'没有被调用 – Nishant

我发现你的代码有任何问题..你可以尝试setOnItemClickListener而不是？ –
