RecyclerView 购物车功能

ゝ一世哀愁。 2022-02-27 07:54 302阅读 0赞

**前言： **

RecyclerView是android 最常见的列表控件，它现在几乎已经代替了listVIew和GridView的使用，RecyclerView自带强大的功能，实现多种样式，使用更加简单，封装也很容易，相对于listIView，RecyclerView没有自己的item点击事件，需要开发人员自行通过接口回调来实现点击事件，在近期工作不忙时，我查阅了一些开源的商城项目，写了一套很全面的商城app的购物车功能的demo。

闲话少说先上运行图：

就上传这三张图，了解下大致功能。

## 1.项目搭配代码进行分析(这里只提供主要方法，详细的demo最下方分享) ##

### 1），个数的增加与减少实现： ###

自定义一个类，继承LinearLayoutb (AddSubView)

对加减按钮进行编写

通过回调方法进行回调

响应回调方法

### 2）最外层布局 ###

### 4）适配器的编写 ###

public class ShoppingCartAdapter extends RecyclerView.Adapter<ShoppingCartAdapter.ViewHolder> {
    
        private Context context;
        private List<GoodsBean> mAllData;
        private TextView mTvShopcartTotal;
        private CheckBox mCheckboxAll;
        /**
         * 完成状态下的删除
         */
        private CheckBox mCbAll;
    
    
        public ShoppingCartAdapter(Context mContext, List<GoodsBean> allData, TextView tvShopcartTotal, CheckBox checkboxAll, CheckBox cbAll) {
    
            this.context = mContext;
