[android-developers] ICS Listview Selector

[authorwjf]

Howdy UI Gurus!

I am having an issue with a custom list selector.  I tried to whittle
the code down to a very small subset that runs independently of my
project in hopes someone more familiar with the UI framework than I
could assist.  Basically, I have a custom selector I have been using
for listviews in my application.  It has 2 states, a gray gradient,
and everything else.  In the case of everything else, I want the view
to be transparent.  It worked fine and still does on the majority of
platforms, however on ICS devices after the user touches and releases
an item in the list there is an animation of an orange bar that fades
in and away.  I don't want this--but I'm not sure how to get rid of
it.  Are there new states now (or behavior?) in later versions of the
OS?  I'm not sure.  Here is the code that demonstrates the issue on
the emulator.  It works as I'd like on Gingerbread devices, but not on
ICS.  I don't know about Honeycomb.  Thanks in advance to anyone who
posts a reply.

Cheers!
