RussianI ended up fixing it by stop using setBackground color and using a image instead.
Listview and CustomViewBinder

Pergunta
So i have a list of 7 days worth of information to display. When the list is populated the @+id/image shows correctly (as far as i can see) and when i scroll down and back up the image is changed. In the case where the image is populated with another image it works fine, in the case of when an image is populated with a color is messes up.
I know there's probably some room for improvement here so if you have suggestions please explain them along with showing me how, thanks in advance!
