alignParentBottom not used

Question

I had a layout which used LinearLayouts instead of RelativeLayouts. I want to add the borderless buttons to my layouts as shown here: How to create standard Borderless buttons (like in the design guidline mentioned)?

So, to use this, I had to change my LinearLayouts to RelativeLayouts. This has worked fine for the most part. However, when I try to use the alignParentBottom for one of the RelativeLayouts it doesn't work - it just overlaps with one of my other buttons.

This is my xml:

EDIT: This is updated code. The ScrollView overlaps the 48dp RelativeView:

Answer 1

Use the following properties on the ScrollView:

<RelativeLayout android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout 
        android:id="@+id/bottom" 
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:layout_alignParentBottom="true">
        <!-- rest of the code -->
    </RelativeLayout>

    <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_above="@id/bottom" 
        android:layout_alignParentTop="true" >
        <!-- rest of the code -->
    </ScrollView>
<RelativeLayout>
