TabListener,ActionBarSherlock片段和ListFragment,PageAdapter的混合? 一团糟

我有一个有2个片段的活动。 我已经决定使用PageAdapter在两个视图之间滑动,但为了保持与androiddevise最佳实践的接近,我还决定使用操作栏选项卡(固定的)。 我正在使用ActionBarSherlock和这里的一些代码来实现选项卡。 只有pageadapter的活动工作出色,现在我有两个问题:1)第一个片段(MatchRugbyButtonFragment)oversmpress自己的图像,所以如果我触摸它,移动或改变的东西,我看到上方的图像工作片段。 2)当我去第二个片段时,首先丢失所有variables(定时器复位,计数器复位,ecc)。 我必须创buildtablistener,因为一个片段是一个SherlockFragment,另一个是SherlockListFragment,并导致一个错误,它不能将片段转换为SherlockListFragment。 这是活动:

这里是pageadapter类:

!!!问题解决了!!!

我不知道这是否是最好的做法,但我已经解决了我的问题,感谢这个页面 ,我想分享它来帮助需要的人。 那里的操作栏是“原创”,所以我不得不定制一下,以适应ABS。 这是最后一个类,它处理选项卡和Swype的每个方面(包括自动地将选项卡放在操作栏内部或外部):

我在这里写了一个教程 – http://lomza.totem-soft.com/tutorial-actionbarsherlock-tabs-viewpager-listfragment-with-tab-listeners-and-more/关于这个话题&#x3002; 基本实现与David的post非常相似。 也许,这对某个人是有用的;)
