I'm working on the UI for an application I'm writing but I've hit a bit of a wall and wonder if there is anyone out there can give me some advice.
I've created a ViewFlipper to slide between two ListViews. It works well enough so far however there seems to be an issue with drawing.
The ListView has a background, the rows are transparent. When I select a row and the slide to the next list occurs the rows turn (I think) transparent, then the ListView background is painted once the animation stops. What is odd however is that the space below the rows do not turn transparent.
It's a bit hard to explain so I recorded a video, http://www.youtube.com/watch?v=8fEEf6_DyPo
If I put a background on the rows then they do not turn transparent.
Thanks for your time.
You'll find it does this when scrolling too. Try setting "android:cacheColorHint="#00000000" on your listview.
This is due to rendering issue caused by an optimization of the Android framework
To disable the optimization, simply use the transparent color #00000000
