Thanks Mark, I think you managed to clarify for me why it's not working. And yes, I'm now convinced that RelativeLayout is the correct option in this case.
I believe that layout_gravity (for LinearLayout) probably only has an effect if it specifies a direction that is orthogonal to the orientation of the layout. Ie if the LinearLayout orientation is horizontal then the only acceptable layout_gravity options fors its children are top, bottom etc (and NOT left, right, center_horizontal). Happy now.
