我有一个列表视图，每个项目加载一个片段，其中包含另一个片段。第一次收费很好，但当我返回lisview并重新加载另一个片段（或相同）时，我收到了这个错误：
view = inflater.inflate(R.layout.fragment_text_receiver, container, false);

我不知道会发生什么。 XML文件行34是声明片段的地方：
<fragment
android:id="@+id/fragmentComments"
android:name="com.gzanitti.tsar.fragments.CommentsFragment"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/txtReceiverText"
android:layout_alignParentBottom="true"
android:layout_alignRight="@+id/txtReceiverText"
android:layout_alignTop="@+id/txtReceiverTitle"/>
重复ID可能有些问题？某种形式的“释放”？

第一次工作正常，但当我回来并尝试加载另一个时，会发生此错误
答案 0 :(得分：1)
解决方案是强制将子片段移除到frament parent detach上。
@Override
public void onDetach() {
super.onDetach();
getActivity().getSupportFragmentManager().beginTransaction().remove(fragmentComments).commit();
}
