片段中的选项卡式导航

Question

所以我有一个处理我的碎片的导航抽屉。在那些片段中，我想实现选项卡式导航。我已经搜索了高低，以确定这是否可行。但我找不到它是不是。从查看事物我不认为它是标签片段实现需要FragmentActivity，我的导航抽屉不能使用FragmentActivitys。

NavDrawers可以扩展扩展Fragment但不扩展FragmentActivity的类，这就是为什么我认为这是无法实现的。 Android开发者文档（http://developer.android.com/training/implementing-navigation/lateral.html）上的滑动视图就是为什么我不相信我能做到这一点。除非有不同的方式来实现抽屉，而不是我正在做的事情。

但我也知道Gmail实现了类似的功能。他们有一个NavDrawer实现，具有选项卡式导航功能 - 您可以在电子邮件之间滑动。这给了我一些希望......

任何方向都会很棒。

这是我的navdrawer实现，最重要的是我没有使用v4.support库，我使用的是最近的库：
