How to put horizontal recirculation inside vertical scroll

I am trying to fit six horizontal rows of recyclerview inside a vertical scroll. What I have is a top row of reusable buttons that allow me to select a date followed by six horizontal views that allow me to select items, and then a bottom row of three buttons

The code for my non-scrollable snippet looks like this:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="db.cbm.com.myapp.MenuPickerFragment">

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="center"
        android:orientation="vertical">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="0.25"
            android:text="@string/pick_menu" />

        <LinearLayout
            android:id="@+id/datePickerView"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_gravity="center_horizontal"
            android:layout_weight="1"
            android:orientation="horizontal">

            <android.support.v7.widget.RecyclerView

                android:layout_height="match_parent"></android.support.v7.widget.RecyclerView>
        </LinearLayout>

        <LinearLayout

                    android:layout_height="match_parent"></android.support.v7.widget.RecyclerView>
            </LinearLayout>

            <LinearLayout

                android:layout_width="match_parent"

            <Button

                android:text="@string/save" />

            <Button

                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 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?
