After additional testing, I've confirmed that the mutate() option doesn't allow the use of one Drawable on multiple view under the following conditions unless there is a trick to it that I'm missing.
1. Using a CursorAdapter with a ListView (Using newView and bindView, haven't tried with getView as it would take a rework of code) 2. GradientDrawable created programmatically (the only way you can do it and customize the gradient colors on the fly) 3. GradientDrawable assigned with setBackgroundDrawable() 4. ListView items having different heights and/or widths Maybe the "state" of the drawable doesn't include the height and width of the object, but there isn't really anything that shows what is included in the "state". Seeing that the alpha was included, one would have thought things like size would have also been included. I'd like to go to reusable Drawables as it would simply things, so if anyone has a viable solution, that would be great.
