什么是活性片段已被清除指数：-1意思，如何解决呢？

问题描述

我有与一个标签式界面自定义的滑动菜单的活动。出于某种原因，我的一个片段（也是唯一一个）有这个错误，我似乎无法找到它在做什么。

I've got an Activity with a custom sliding menu for a tab-like interface. For some reason, one (and only one) of my fragments has this error and I can't seem to find what it's doing.

下面是堆栈跟踪。

E/FragmentManager(13024): Failure saving state: active SettingsFragment{427b2918} has cleared index: -1
E/FragmentManager(13024): Activity state:
E/AndroidRuntime(13024): FATAL EXCEPTION: main
E/AndroidRuntime(13024): java.lang.IllegalStateException: Failure saving state: active SettingsFragment{427b2918} has cleared index: -1
E/AndroidRuntime(13024):    at android.support.v4.app.FragmentManagerImpl.saveAllState(FragmentManager.java:1700)
E/AndroidRuntime(13024):    at android.support.v4.app.FragmentActivity.onSaveInstanceState(FragmentActivity.java:527)
E/AndroidRuntime(13024):    at com.actionbarsherlock.app.SherlockFragmentActivity.onSaveInstanceState(SherlockFragmentActivity.java:127)
E/AndroidRuntime(13024):    at com.slidingmenu.lib.app.SlidingFragmentActivity.onSaveInstanceState(SlidingFragmentActivity.java:50)
E/AndroidRuntime(13024):    at com.client.activities.BaseMenuActivity.onSaveInstanceState(BaseMenuActivity.java:139)

该片段是超级简单。它是所有子类SherlockFragment并重写onCreateView和onActivityCreated设置视图。它有一些按钮，导航到其他片段。

The fragment is super simple. All it does is subclass SherlockFragment and override onCreateView and onActivityCreated to setup the view. It's got some buttons that navigate to other fragments.

我甚至无法可靠地重现此错误。任何想法？

I can't even reliably reproduce this error. Any ideas?

推荐答案

在这种情况下，我想，当你想连接你的片段，它见过像我的code

in this case i Guess when you want to attach you're fragment , it seen like my code

       case 2:
            ft.replace(R.id.content_frame, **xxxx**, "2");
            ft.detach(**yyyyyyy**);
            ft.attach(**yyyyyyy**);

code以下是错误的，正确的code是

code below is wrong and correct code is

         case 2:
            ft.replace(R.id.content_frame, **xxxx**, "2");
            ft.detach(**xxxx**);
            ft.attach(**xxxx**);

也许你有这样的错误，我希望对你有所帮助。
