Android RelativeLayout: How to put a view above another view, without necessarily touching?

I am displaying a ListView that can have any number of rows. I want the ListView to wrap the content. I also want some text to be at the bottom of the screen, regardless of the size of the list. Like so:

What I want to happen

My attempt at making this happen is below, but when the content is large, it causes it to look like the bottom left image.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@color/blue">
<TextView
android:id="@+id/fine_print"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_below:"@+id/table"
android:gravity="center_horizontal"
/>
<ListView
android:id="@+id/table"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/white_box">
</ListView>
</RelativeLayout>


And adding

android:layout_above="@id/fine_print"


to @id/table makes it look like the bottom right image.

What ends up happening

How can I make it do what I want?

Answer

This seems a bit weird, but here's how I got it working. Since the text at the bottom is of size "8dip", and takes up either 1 or 2 lines depending on screen orientation, I put a padding of "16dip" below the list.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="@color/blue">
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/details_wrapper"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical"
        android:paddingBottom="16dip">
        <ListView 
            android:id="@+id/table" 
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content"
            android:background="@drawable/white_box">
        </ListView>
    </LinearLayout>

<TextView
    android:id="@+id/fine_print"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"  
    android:gravity="center_horizontal"
  />
</RelativeLayout>

Still open to suggestions on making this cleaner, though.
