我移植我的Andr​​oid应用程序，以蜂窝我才能使用片段做了一次大的重构。在我的previous版本，当我pressed的主页按钮，我以前做的一个ACTIVITY_CLEAR_TOP以重置回堆栈。

I ported my Android app to honeycomb and I did a big refactor in order to use fragments. In my previous version, when I pressed the Home button I used to do a ACTIVITY_CLEAR_TOP in order to reset the back stack.

现在我的应用程序仅仅是与多个片段（fragments）一个活动，所以当我preSS的主页按钮，我只需更换里面的片段之一。我怎样才能清除，而不必使用startActivity与ACTIVITY_CLEAR_TOP标志我的背部栈？

Now my app is just a single Activity with multiple fragmens, so when I press the Home button I just replace one of the fragments inside it. How can I clear my back stack without having to use startActivity with the ACTIVITY_CLEAR_TOP flag?

推荐答案

I类似这里发布的内容

这是勒夫的回答，从戴安娜Hackborn：

From Joachim's answer, from Dianne Hackborn:

我最终只使用：

FragmentManager fm = getActivity().getSupportFragmentManager();
for(int i = 0; i < fm.getBackStackEntryCount(); ++i) {    
    fm.popBackStack();
}

但也同样使用了类似：

But could equally have used something like:

FragmentManager.popBackStack(String name, FragmentManager.POP_BACK_STACK_INCLUSIVE)

这将弹出所有状态到已命名的。然后，您只需更换片段，你想要什么

Which will pop all states up to the named one. You can then just replace the fragment with what you want
