How to set background color of a View
You will need to define a custom `StateListDrawable` resource, cloned perhaps from the one Android uses for buttons by default, where you change the nine-patch images to be gradients. You might be able to define those gradients in XML, which would mean they would stretch nicely.
Problem
I have to create a colored button with gradient fill(starting from the middle of the button along Y axis). If I set the background property of the button to the color I want, I lose the rounded look and feel of a button and also the gradient fill(It looks like a `TextView` with a background). Also, I want this color to change when the user depresses the button. Can i specify this via selector XMLs(Color State Lists)? Any tutorials or links that can help me here is appreciated. Thanks.
