I have a list view using a layout that has a background color of #8000.
When I scroll the list, the list item background color change to a
solid color, in this case black. Seems it's ignoring the alpha
transparency value on scroll.
Is there a way to make it not do that?
Thanks.

Use this:

http://developer.android.com/reference/android/widget/AbsListView.html#attr_android:cacheColorHint
Note that doing this means that ListView can't use important drawing
optimizations, so on

Looks like setCacheColorHint() exists for the list view itself but my
problem is with list items, not the list.

You need to call setCacheColorHint() on the ListView itself. You need
do this only once.

Like this?
list = (ListView) findViewById( R.id.list );
int color = Color.argb( 80, 0, 0, 0 );
list.setCacheColorHint(
You need to set the cache color hint to 0,0,0,0, not 80,0,0,0. And you
still set the background color of your items the way you want.
