本文详细介绍了如何在电商系统中实现商品购物车功能，探讨了购物车的增删改查操作，并利用适配器模式解决了不同商品类型接口不兼容的问题，确保了系统的灵活性和扩展性。

public class GoodAdapter extends RecyclerView.Adapter<GoodAdapter.ViewHolder> {
    private Context context;
    private List<ShopBean.DataBean.SpusBean> list;
    private int parentPosition=-1;

    public GoodAdapter(Context context, List<ShopBean.DataBean.SpusBean> list, int parentPosition) {
        this.context = context;
        this.list = list;
        this.parentPosition = parentPosition;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View inflate = LayoutInflater.from(context).inflate(R.layout.goods_list, viewGroup, false);
        return new ViewHolder(inflate);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder viewHolder, int i) {
        Glide.with(context).load(list.get(i).getPic_url()).into(viewHolder.goods_image);
        viewHolder.goods_check.setChecked(list.get(i).isChecked());
        viewHolder.goods_name.setText(list.get(i).getName());
