Android 折叠工具栏布局：在顶部固定自定义布局

我想做的是：我想在一个折叠工具栏布局中显示一个地图，地图下面应该是一个包含两个控件的自定义布局。下面是一个回收视图。我希望能够滚动自定义布局以及RecyclerView，但修复顶部的自定义布局，同时RecyclerView保持滚动。 下面是我想要实现的图像（灰色=地图；红色=自定义布局；绿色=回收视图）：

这是我到目前为止所拥有的。它工作得很好，除了自定义布局（红色）在到达屏幕顶部时不会停止滚动

实现这种行为最简单的方法是什么？

答案其实很简单。我只需要将自定义布局移到AppBarLayout中

布局如下：

将app:layout\u collapseMode=“pin”红色视图中的该属性添加到屏幕顶部的pin。
