如何在 RecyclerView 中使用 FrameLayout

Question

我想在回收站视图中使用框架布局。框架布局是在一个自定义类中定义的，该类包含两件事：一个加载微调器和一个按钮。

当用户单击按钮时，我希望按钮隐藏并加载微调器以显示。

自定义类布局：

<FrameLayout
        android:id="@+id/foreground"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/SG_White"
        android:clickable="true"
        android:focusable="true">

        <ProgressBar
    android:id="@+id/progress_loader"
    style="?android:attr/progressBarStyle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:visibility="@{model.showSpinnerTrue}" />

        //BUTTON CODE
</FrameLayout>

但我收到了这个严重的错误：

我认为这个错误意味着我不能在 recyclerview 中使用 framelayout？

如果没有，如何在 recyclerview 的特定索引之上显示加载微调器？

我认为 FrameLayout 并不意味着是回收站视图的项目。使用线性布局会更好，因为它更容易，如果您不想要，可以使用卡片视图，我认为它非常适合回收者视图并且对用户更有吸引力。
