inflater.inflate出错

标签: android android-fragments android-inflate

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);

ERROR:

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();
}
