Question

In this adapter i am doing add and minus products. after adding products in array.the problem is when i am adding multiple products in array the first data is wiped automatically in array.

public class PackageOffersSubCategoryAdapter extends RecyclerView.Adapter<PackageOffersSubCategoryAdapter.MyViewHolder> {

    private Context context;
    private List<PackageOffersSubCategory> packageOffersSubCategoryList, selectedSubService;
    private String string, isClicked = "";
    private int totalPrice = 0;
    private  int index;

    public PackageOffersSubCategoryAdapter(Context context, List<PackageOffersSubCategory> packageOffersSubCategoryList, String id) {
        this.context = context;
        this.packageOffersSubCategoryList = packageOffersSubCategoryList;
        this.selectedSubService = selectedSubService;
        this.string = id;
        this.isClicked = isClicked;
    }
