2. Add getMDcolor() to your class:

private int getMDcolor(String mdcolor) {
    int returnColor = 0;
    String[] mdcolors = new String[]{
            "mdcolor_50",

            "mdcolor_A400",
            "mdcolor_A700",
            "extras"};
    if (Arrays.asList(mdcolors).contains(mdcolor)) {
        TypedArray colors = null;
        switch (mdcolor) {
            case "mdcolor_50":
                colors = mContext.getResources().obtainTypedArray(R.array.mdcolor_50);

                break;

            case "mdcolor_A400":
                colors = mContext.getResources().obtainTypedArray(R.array.mdcolor_A400);
                break;
