1、本地
取出需要解析的Json字符串
转化为UTF-8的格式
将字符串json转换为json对象
根据Json里面的key读取数据

//将json文件(存放在本地的res/raw)读取到buffer数组中
            InputStream is = this.getResources().openRawResource(R.raw.getcart);
            byte[] buffer = new byte[is.available()];
            is.read(buffer);
//  将字符数组转换为UTF-8编码的字符串
            String json = new String(buffer, "UTF-8");
            将字符串json转换为json对象，以便于取出数据
            JSONObject jsonObject = new JSONObject(json);
//解析info数组，解析中括号括起来的内容就表示一个数组，使用JSONArray对象解析
            JSONObject objectInfo = jsonObject.getJSONObject("info");
            JSONArray arraygroup = objectInfo.getJSONArray("group");
            for (int i = 0; i < arraygroup.length(); i++) {
                ShopBean shopBean = new ShopBean();
                JSONObject item = arraygroup.getJSONObject(i);
                int seller_uid = item.getInt("seller_uid");
                String seller_name = item.getString("seller_name");

                shopBean.setSeller_uid(seller_uid);
                shopBean.setSeller_name(seller_name);

                JSONArray arraygoods = item.getJSONArray("goods");
                for (int j = 0; j < arraygoods.length(); j++) {
                    JSONObject jtem = arraygoods.getJSONObject(j);
                    int stock_id = jtem.getInt("stock_id");
                    String goods_name = jtem.getString("goods_name");
                    int qty = jtem.getInt("qty");
                    boolean is_choose = jtem.getBoolean("is_choose");
                    int price = jtem.getInt("price");
                    String goods_img = jtem.getString("goods_img");
                    String extend = jtem.getString("extend");
                    int stock_num = jtem.getInt("stock_num");
                    int goodsTotalPrice = jtem.getInt("goodsTotalPrice");
                    double rate = jtem.getDouble("rate");

                    //把商品的属性值添加到shop实体类中
                    shopBean.setStock_id(stock_id);
                    shopBean.setGoods_name(goods_name);
                    shopBean.setQty(qty);
                    shopBean.setIs_choose(is_choose);
                    shopBean.setPrice(price);
                    shopBean.setGoods_img(goods_img);
                    shopBean.setExtend(extend);
                    shopBean.setStock_num(stock_num);
                    shopBean.setGoodsTotalPrice(goodsTotalPrice);
                    shopBean.setRate(rate);
                    shopBeanList.add(shopBean);

                }
