Question

我有一个显示DialogFragment的活动，在该对话框片段中我有一个包含一个按钮的linearlayout，以及一个我要显示信息的fragmentLAyout。

我必须显示一个元素列表，如果有任何元素被按下，我必须显示它们的详细信息。我认为最好的方法是使用片段，当试图调用

时

FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        transaction.add(R.id.framePlaceHolder, listAccountFragment).commit();

创建listAccountFragment后，我收到此错误
