Android使用自带JSONObject解析JSON数据

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import android.content.Context;

public void allInfoFromJson(String jsonStr){

/*{ "listMsg":"数据获取成功",
" list ":[
{"busId":1,"busLine":"惺惺惜惺惺","busName":"501","cityId":2,"districtId":1,
"firstTime":"8:00","lastTime":"19:00","price":4,"version":0},
{"busId":2,"busLine":"502","busName":"502","cityId":2,"districtId":2,
"firstTime":"2","lastTime":"2","price":2,"version":0},
{"busId":3,"busLine":"aaa","busName":"601","cityId":2,"districtId":1,
"firstTime":"aa","lastTime":"aa","price":1,"version":0}
],
"nVersion":3} */
try {
//JSONObject jsonObject=new JSONObject(jsonStr).getJSONObject("list");

JSONArray jsonArray=new JSONObject(jsonStr).getJSONArray("list");

for(int i=0;i<jsonArray.length();i++){

JSONObject jsonObject=(JSONObject)jsonArray.get(i);

String busLine=jsonObject.getString("busLine");
String busName=jsonObject.getString("busName");
Integer cityId=jsonObject.getInt("cityId");
Integer districtId=jsonObject.getInt("districtId");
String firstTime=jsonObject.getString("firstTime");
String lastTime=jsonObject.getString("lastTime");
Double price=jsonObject.getDouble("price");

Bus bus=new Bus(busName,busLine,firstTime,lastTime,price,cityId,districtId);
BusService busService=new BusService(context);
busService.save(bus);
}

} catch (JSONException e) {
e.printStackTrace();
}
}
