How to fill in the gap between two views in RelativeLayout

Question

I have two kinds. Top view set to ...

 android:layout_alignParentTop="true"

And below is set to ...

 android:layout_alignParentBottom="true"

How to fill the remaining space with a third view? According to this answer here , I should use a frame layout similar to this ...

<FrameLayout 
   android:layout_below="@+id/toplayout" 
   android:layout_above="@+id/bottomlayout"/>

But then I need to specify the height and width. What height and width should I indicate?

Here is my solution

<RelativeLayout
     ...
   >
        <YourLayout
         android:id="@+id/toplayout"
         android:layout_alignParentTop="true"
        />

        <YourLayout
         android:id="@+id/bottomlayout"
         android:layout_alignParentBottom="true"
        />

        <MiddleLayout 
          <!-- in your case it is FrameLayout -->
           android:layout_width="match_parent"
           android:layout_height="match_parent" 
          <!-- or android:layout_height="wrap_content" according to the_profile -->
           android:layout_below="@+id/toplayout" 
           android:layout_above="@+id/bottomlayout"/>
    </RelativeLayout>

Hope this helps
