Android GUI layouts. How to create a fixed layer with control buttons on top of the data layer?

Question

Android

Android specialists, I would like to know your opinion. There is a LinearLayout - "lists_layout" with a vertical arrangement of internal elements. It has some, dynamically determined, number of TextView elements.
How to make the lists_layout layer, when there are a lot of elements in it, "dive" under the next LinearLayout containing control buttons. And if necessary, a vertical scrollbar appeared in lists_layout?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent" android:layout_height="match_parent"
  android:gravity="center_vertical|center_horizontal"
  android:orientation="vertical">
   
    <LinearLayout android:id="@+id/lists_layout"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="0dp" android:layout_weight="1" />

  <LinearLayout android:gravity="center|bottom"
    android:layout_weight="1" android:layout_width="match_parent"
    android:layout_height="0dp" android:orientation="horizontal">
    <Button 
        android:layout_height="wrap_content" 
        android:text="Set"
      android:layout_width="90dp" 
      android:id="@+id/Settings" />

    <Button 
        android:layout_height="wrap_content" 
        android:text="Sort"
      android:layout_width="90dp" 
      android:id="@+id/SortSelect" />
    <Button 
        android:layout_height="wrap_content" 
        android:text="Create"
      android:layout_width="90dp" 
      android:id="@+id/CreateListButton" />
  </LinearLayout>
</LinearLayout>

Here is an example picture :)

Answer 1

Put everything in a FrameLayout

FrameLayout {
    ScrollView {
         LinearLayout {
             TextView  x n
         }
    }
    LinearLayout {
          кнопки
    }
}
