Android的本地Json解析

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);                }
