Do you mean the Carbon's RippleDrawable? If so, then the following code is used by Carbon to init RippleDrawable using xml params.

public static void initRippleDrawable(RippleView rippleView, TypedArray a, int[] ids) {
    int carbon_rippleColor = ids[0];
    int carbon_rippleStyle = ids[1];
    int carbon_rippleHotspot = ids[2];
    int carbon_rippleRadius = ids[3];

    View view = (View) rippleView;
    if (view.isInEditMode())
        return;

    ColorStateList color = getDefaultColorStateList(view, a, carbon_rippleColor);
    if (color == null)
        color = a.getColorStateList(carbon_rippleColor);

    if (color != null) {
        RippleDrawable.Style style = RippleDrawable.Style.values()[a.getInt(carbon_rippleStyle, RippleDrawable.Style.Background.ordinal())];
        boolean useHotspot = a.getBoolean(carbon_rippleHotspot, true);
        int radius = (int) a.getDimension(carbon_rippleRadius, -1);

        rippleView.setRippleDrawable(RippleDrawable.create(color, style, view, useHotspot, radius));
    }
}

Setting Carbon's RippleDrawable should be as easy as calling the last line. Please note that this call composes RippleDrawable with the current background.

rippleView.setRippleDrawable(RippleDrawable.create(color, style, view, useHotspot, radius));

You can also set RippleDrawable as background.

view.setBackground(RippleDrawable.create(color, style, view, useHotspot, radius));

Ok but how i can change the RippleDrawable color? i'm stuck in this part...

You can pass any color as the first parameter, just like it's done in the example I posted.
