使用Gson解析带数组的json数据

json数据格式为：

{"MSG_CD":"000000","TXN_CD":"4050009","LIST":"","MSG_INF":"SUCCESS",
"REC":[
{"MERC_ID":"800075500050002","CRE_DT":"20160523","BUS_TYP":"0010",
"MBL_NO":"15012400420","RN":"21","REAL_MERC_NM":"fdsgfd","MERC_NM":"fdsgfd",
"PAY_TYP":"1","EXP_TM":"20160530092907","CRE_TM":"092907",
"ORD_NO":"201605150000111813","ORD_DT":"20160523","ORD_STS":"RP",
"BUS_CNL":"APP","MERC_ORD_NO":"20160523092659","ORD_AMT":"4"}]}

1.定义数据类

public class BillODBean {private String MSG_CD; private String MSG_INF;public List<OrderBean> REC;public class OrderBean{private String CRE_DT; private String CRE_TM;private String ORD_STS;private String ORD_AMT;private String MBL_NO;private String MERC_ORD_NO;}}

2.使用Gson对象解析

Gson gson = new Gson();BillODBean billODBean = mGson.fromJson(message, BillODBean.class);ArrayList<OrderBean> orderBeans = (ArrayList<OrderBean>) billODBean.getREC();
