Solution 1:

Create a TransitionDrawable to change between two drawables that you use for the background.

<?xml version="1.0" encoding="UTF-8"?><transitionxmlns:android="http://schemas.android.com/apk/res/android"><!-- use whatever drawables you want, gradients, shapes etc--><itemandroid:drawable="@drawable/start" /><itemandroid:drawable="@drawable/end" /></transition>

TransitionDrawabletrans= (TransitionDrawable) myLayout.getBackground();
trans.startTransition(2000);
