How to change the color of overscroll edge and overscroll glow

Question

How to Change color of over-scroll edge and over-scroll glow or how to change the white color (default color) of android release 5.0 lollipop?

Answer 1

In pre-lollipop the glow effect is actually a Drawable embedded in the OS's resources, you can apply a ColorFilter on that:

public static void changeOverScrollGlowColor(Resources res, int colorID ) {
    try {
        final int glowDrawableId = res.getIdentifier("overscroll_glow", "drawable", "android");
        final Drawable overscrollGlow = res.getDrawable(glowDrawableId);
        overscrollGlow.setColorFilter(res.getColor(colorID), android.graphics.PorterDuff.Mode.SRC_ATOP);

        final int edgeDrawableId = res.getIdentifier("overscroll_edge", "drawable", "android");
        final Drawable overscrollEdge = res.getDrawable(edgeDrawableId);
        overscrollEdge.setColorFilter(res.getColor(colorID), android.graphics.PorterDuff.Mode.SRC_ATOP);
    } catch (Exception ignored) {
    }
}

Calling it once in onCreate is enough.

changeOverScrollGlowColor(getResources(), R.color.colorPrimary);
