如何将水平回收视图放在垂直scrollview

Question

我试图在垂直滚动视图中放置六个水平回收视图行。我所拥有的是一系列顶级回收按钮，让我选择一个日期，然后是六个水平回收者视图，让我选择项目，然后是底行三个按钮

没有滚动视图的片段代码如下：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

                android:text="@string/done" />
        </LinearLayout>
    </LinearLayout>
</FrameLayout>

The above works correctly except the images in the six menu picker recycler view rows are too small so I would like to increase their size and put them into a vertical scroll view.

Here's what I think I want but it doesn't work, none of my recyclerviews are present or at least they're not initialized and I don't see any rows. Any idea what I'm doing wrong?
