android - Custom overscroll glow/edge color for ListView?

Question

I have a ListView, and a custom style that basically looks just like Holo, but with yellow accents instead of blue.

When I scroll to the bottom or top of the list, I get the un-fitting blue. I made custom drawables for overscroll_glow.png and overscroll_edge.png, but I don't know how to use them.

How can I get my ListView to use these drawables instead of the system ones?

Would the OverScroller class help?

You can use a reflection-like solution to hack your way to changing this glow color:

int glowDrawableId = context.getResources().getIdentifier("overscroll_glow", "drawable", "android");
Drawable androidGlow = context.getResources().getDrawable(glowDrawableId);
androidGlow.setColorFilter(brandColor, PorterDuff.Mode.MULTIPLY);

I encountered the same problem, and it seems like a good solution, at least until Google adds an API for changing the color (or branding the color): http://evendanan.net/android/branding/2013/12/09/branding-edge-effect/
