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);
