Defined custom shape for button in xml. Now I want to change the color dynamically. How?

Question

I have this:

round_button.xml

Answer 1

I solved it by setting a ColorFilter:

Drawable mDrawable = context.getResources().getDrawable(R.drawable.balloons); 
mDrawable.setColorFilter(new PorterDuffColorFilter(0xffff00,PorterDuff.Mode.MULTIPLY));
myButton.setResource(mDrawable);
