Try this you can use both color code or color directory path

holder.cardViewBusinessListItem.setBackgroundColor(Color.parseColor("#00FF00"));

Card view has a lot of problems. You should instead change the background of the parent view that is inside card view.

<CardView>
    <RelativeLayout> <-- change this view's background instead
        <ABC.../>
        <XYZ.../>
    </RelativeLayout>
</CardView>
