Here is my layer list:

Answer 1

Find your view

LayerDrawable layerDrawable = (LayerDrawable) yourView.getBackground();
GradientDrawable outer = (GradientDrawable) layerDrawable.findDrawableByLayerId(R.id.outer);
GradientDrawable middle = (GradientDrawable) layerDrawable.findDrawableByLayerId(R.id.middle);
GradientDrawable inner = (GradientDrawable) layerDrawable.findDrawableByLayerId(R.id.inner);

Set color

outer.setColor(Color.parseColor(#000000));
inner.setColor(Color.parseColor(#FFFFFF));
