    Activity a;
    ArrayList<String> Custno;
    ArrayList<String> Custname;
    ArrayList<String> Custstatus;

    ArrayList<String> Customermapping;


    HashMap<Integer, Integer> statusArray = new HashMap<>();


    public CustomAdapter(Activity a, ArrayList<String> custno, ArrayList<String> custname, ArrayList<String> custstatus,ArrayList<String>customermapping,HashMap<Integer, Integer> statusArray1) {
        this.a = a;
        Custno = custno;
