Answer 1

You need to make the items in the ListView transparent by setting following on the ListView:

android:background="@android:color/transparent"
android:cacheColorHint="@android:color/transparent"

Then your items Layout needs to have whatever color/image (this will be put on top of the transparency).

This should work but will be heavy work on Android as transparency really takes its toll on Android especially when it's in a ListView where there is a lot of UI updates.
