原因：java.lang.IllegalStateException:替换活动中的任何片段时，在onSaveInstanceState之后无法执行此操作

我试图替换ListView setOnItemClickListener上的片段，但遇到以下崩溃问题：

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，我点击浮动按钮打开一个活动，下面是代码：

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

然后，onActivityResult我尝试替换片段，如：

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);

}

有人知道我该如何解决撞车问题吗

使用transaction.commitAllowingStateLoss可能有效

谢谢@liubaoyua 您的回答解决了我的问题，但transaction.commitAllowingStateLoss不能单独工作 首先，我重写onSaveInstanceStateBundle outState方法并从中删除超级方法调用，然后提交AllowingStateLoss工作

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