原因：java.lang.IllegalStateException：从活动中替换任何片段时，onSaveInstanceState之后无法执行此操作

Question

我正在尝试替换listeview setOnItemClickListener上的片段，但出现以下崩溃问题：

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=65599, result=-1, data=Intent { (has extras) }} to activity {com.demo/com.demo.ui.SipHome}: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

在这里，我打开一个活动onclick浮动按钮，下面是该代码：

Intent intent = new Intent(getActivity(), PaycallContacts.class);
startActivityForResult(intent, REQUEST_CREATE_CHAT);

然后在onActivityResult（）上，我尝试替换片段：

if (requestCode == REQUEST_CREATE_CHAT) {

Fragment currentFragment = getChildFragmentManager().findFragmentById(R.id.frameChat);
        if (currentFragment instanceof ConversationFragment && getChildFragmentManager().getBackStackEntryCount() > 1) {
            return;
        }

if(!getActivity().isFinishing()) {
            mConversationFragment = new ConversationFragment();
            FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
            transaction.replace(R.id.frameChat, mConversationFragment, "conversation");
            transaction.addToBackStack(null);
            transaction.commitAllowingStateLoss();
            transaction.commit();
        }

        //switchToConversation(conversation);
        openConversation();

        getChildFragmentManager().addOnBackStackChangedListener(addOnBackStackChangedListener);

}

有谁知道如何解决崩溃的想法？

Answer 1

使用transaction.commitAllowingStateLoss()可能有效

Answer 2

谢谢@liubaoyua您的答案解决了我的问题，但transaction.commitAllowingStateLoss（）不能单独工作首先，我重写onSaveInstanceState（Bundle outState）方法并从那里删除super（）方法调用，然后commiteAllowingStateLoss（）工作。

@Override
public void onSaveInstanceState(Bundle outState) {
    //super.onSaveInstanceState(outState);
}
