Ok, so it's not me doing something stupid. :)
Any thoughts as to the best solution?
I wrote a simple test whereby I created a RelativeLayout rather than a
LinearLayout and defined the ViewGroup first and the buttons after,
relative to the ViewGroup, which seemed to work ok in the test. So
did calling buttonA.bringToFront() before starting the animation
(although it screwed up the layout after the animation was complete by
putting the Button A on the far right next to Button B). Neither seem
a very elegant solution to what must be quite a common problem (I
really don't want to have to re-define my whole layout again as that
has implications for the whole app).

The Z adjustment only works for window animations. I thought this was
documented, but apparently not.

I've come across a curious problem:
I have a simple horizontal LinearLayout: Button A - ViewGroup
(vertical LinearLayout containing TextViews) - Button B
It's important to note that the views are defined in the XML in the
above order i.e. Button A, ViewGroup, Button B.
I have a simple TranslateAnimation:
1. Press Button A and the ViewGroup gets animated off the screen to
the right, past Button B.
2. Press Button B and the ViewGroup gets animated off the screen to
the left, past Button A.
In the case of #1, the animation happens with the ViewGroup being
animated *behind* Button B.
In the case of #2, the animation happens with the ViewGroup being
animated *above* Button A.
This happens specifically because Button A was defined before the
ViewGroup in the layout XML. I've tried changing the Z adjustment for
the animation but this has no effect.
What I want is to have both animations happen behind the buttons (i.e
#2 same as #1). I don't want to have to re-arrange my layout to have
to define the ViewGroup first and I've tried bringing Button A to the
front but that messes with the overall layout when the ViewGroup is
off the screen, with Button A ending up next to Button B on the right.
Any ideas? It seems like the Z adjustment isn't doing what it should.
