Defining a ScrollView without setting it's height

Question

Hello, I created a ScrollView and want it to expand to the available space, without having to set a fixed height (i.e. "250px") for it.

As such, I created a RelativeLayout. The basic outline follows:

<RelativeLayout>
    <LinearLayout 
        android:id="@+id/x" >
        <TextView 
            android:text="Title" ... />
    </LinearLayout>
    <ScrollView 
        android:id="@+id/y"
        android:layout_below="@id/x" />
    <LinearLayout
        android:layout_below="@id/y" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        android:gravity="center_horizontal|bottom" >
        <Button ...>
    </LinearLayout>
</RelativeLayout>

The idea of the Layout is to have the Title on top, the Button in near the bottom of the screen and the ScrollView in between those two.

The problem is, I still have to use android_height in the definition of ScrollView, so its still fixed to that height.

How can I work around this?

Thanks.

Seems like this layout might be simpler with a LinearLayout as the outer element, with orientation="vertical"

Set the layout_height of all elements to wrap_content. Set the weight of all elements other than the scrollView to 0, and the weight of the scrollView to 1.
