解决方案

  

不能保留嵌套在其他片段fragements

这是嵌套的片段的限制。我猜一个或多个孩子的片段有 setRetainInstance（真）的地方在其code。您需要删除，以prevent错误。

编辑：在进一步阅读，似乎如果父片段呼吁 setRetainInstance（真）那么就会造成由于这样的事实，试图保持母体实例也试图保留子相同的异常片段

there is sth wrong with my Application,I try to add three Fragments in another Fragment,then the Eclipse show this:

java.lang.IllegalStateException: Can't retain fragements that are nested in other fragments

this is my code in the childFragments

getChildFragmentManager().beginTransaction()
            .add(R.id.shop_fragment_container, shopTopOneFragment)
            .add(R.id.shop_fragment_container, shopTopTwoFragment)
            .add(R.id.shop_fragment_container, shopTopThreeFragment)
            .hide(shopTopTwoFragment).hide(shopTopThreeFragment)
            .show(shopTopOneFragment).commit();

any help will be appreciated

解决方案

Can't retain fragements that are nested in other fragments

This is a limitation of nested Fragments. I'm guessing one or more of your child Fragments have setRetainInstance(true) somewhere in their code. You need to remove that to prevent the error.

EDIT: On further reading it seems if the parent Fragment is calling setRetainInstance(true) then it will cause the same exception due to the fact that attempting to retain the parent instance also attempts to retain the child Fragments.
