Android: Have an arbitrary View slide under another View like the software keyboard does
<p>I want to have a View pop in at the bottom of the page exactly like
the software keyboard view does in the compose section of the Mms app.
 It slides in from the bottom, as if it's being added to a vertically
oriented LinearLayout, only making the ListView smaller.  It becomes a
part of the current layout instead of popping up over the top of it.
I'd like to to this exact thing with my own custom View.</p>

<p>Does the question make sense at all?</p>
