在片段整合FragmentActivity [英] Integrating FragmentActivity in Fragment

问题描述

我一直在寻找，但没有找到一个合适的回答我的问题。我在Android开发全新的，努力学习抛样品。我有2个样品，我想放在一起。

I've been searching but didn't find a fitting answer to my question. I'm totally new at android dev and trying to learn throw samples. I've 2 samples that I want to put together.

一个Slidemenu和标签布局。这两个工作的伟大，分别..

A Slidemenu and a Tab layout. Both work great, separately..

对于Slidemenu我使用的Andr​​oidHive例如：

For the Slidemenu i'm using the AndroidHive Example:

的http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/

有关我使用的是Androi开发的例子。标签布局

For the tab layout I'm using the Androi Dev example.

一个菜单项是常规。总的来说，我想有3个标签可见。所以basiclly我想GeneralFargment2在GeneralFragment整合，所以我们有一个滑动菜单和每个菜单项的不同可用选项卡。希望你们能帮助我了。

One of the menu items is General. In General I want to have 3 tabs visible. So basiclly I want to integrate GeneralFargment2 in GeneralFragment, so we have a slide menu and for each of the menu items differed tabs available. Hoping you guys can help me out.

GeneralFragment

    }

GeneralFragment2

 * fragments for each of the sections. We use a

推荐答案

尝试ViewPagerIndicator，这将让你SlideMenu以及导航使用标签

Try ViewPagerIndicator, this will allow you to SlideMenu as well as use Tab for navigation
