Android ViewPager IllegalStateException：onSaveInstanceState 之后无法执行此操作
我正在使用兼容性库中的 ViewPager。我经常从市场报告中看到这种例外情况。
java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
at android.support.v4.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1242)
at android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1253)
at android.support.v4.app.BackStackRecord.commitInternal(BackStackRecord.java:535)
at android.support.v4.app.BackStackRecord.commit(BackStackRecord.java:519)
有什么想法可能会导致它吗？
I am using a ViewPager from the compatibility library. I get this exception quite often from the market reports.
java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
at android.support.v4.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1242)
at android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1253)
at android.support.v4.app.BackStackRecord.commitInternal(BackStackRecord.java:535)
at android.support.v4.app.BackStackRecord.commit(BackStackRecord.java:519)
Any ideas what might cause it?

尝试用
commitAllowingStateLoss()而不是commit()。阅读文档此处。
从此处得到答案。
Try
commitAllowingStateLoss()instead ofcommit(). Read thedocumentation here.
Got answer from here.
您可能在错误的位置调用
FragmentTransaction.commit()。需要在保存状态之前调用它 。You are probably calling
FragmentTransaction.commit()in the wrong place. It needs to be called before state is saved.
