Hey @milosmns this is really useful thanks for sharing. I'm trying to adapt createRippleDrawable() to support the disabled state and for some reason cannot achieve the desired effect. Grey background when disabled and the usual ripple with color when enabled. https://gist.github.com/scottyab/31ea005e10a9115b55ee6501fac866bf any insight would be greatly appreciated.
