I wouldn't be that difficult to make a custom control consisting of an outer panel and an inner panel (the inner panel would be the container for your edittext or button or whatever). The outer panel would be a few dips higher/wider than the inner panel, so you could create a canvas for it and draw a radial semi-transparent gradient: https://www.b4x.com/android/forum/threads/b4x-bitmapcreator-draw-radial-gradients.92853/#content
