从大众点评网抓数据返回的JSON串如何解析

开始接触Android和JAVA不就，最近老师给了个任务，要从大众点评网抓数据，它返回的JSON串（测试）是这样的
{ 
  "status": "OK", 
  "total_count": 16, 
  "count": 1, 
  "businesses": [ 
    { 
      "business_id": 2951611, 
      "name": "香草香草云南原生态火锅", 
      "branch_name": "大理店", 
      "address": "海淀区苏州街55号名商大厦2楼", 
      "telephone": "010-82621976", 
      "city": "北京", 
      "regions": [ 
        "海淀区", 
        "苏州桥" 
      ], 
      "categories": [ 
        "火锅",

      ], 
      "latitude": 39.97193,

      "rating_s_img_url": "http-//i1.dpfile-com/s/i/app/api/16_5star.png", 
      "product_grade": 5, 
      "decoration_grade": 4, 
      "service_grade": 5, 
      "product_score": 9, 
      "decoration_score": 8.7, 
      "service_score": 9.2, 
      "avg_price": 87, 
      "review_count": 4788, 
      "distance": -1, 
      "business_url": "http-//dpurl.cn/p/MV7etBc23J", 
      "photo_url": "http-//i1.dpfile-com/2009-02-28/1647031_b.jpg(700x700)/thumb.jpg", 
      "s_photo_url": "http-//i3.dpfile-com/2009-02-28/1647031_b.jpg(278x200)/thumb.jpg", 
      "has_coupon": 1, 
      "coupon_id": 205955, 
      "coupon_description": "三种优惠，尽享原汁原味", 
      "coupon_url": "http-//dpurl.cn/p/N9a9c1hCZb", 
      "has_deal": 1, 
      "deal_count": 1, 
      "deals": [ 
        { 
          "id": "2-5105493", 
          "description": "香草香草云南原生态火锅!仅售75元,价值100元代金券1张!别样生态美食来袭,精心制作搭配巧妙!慕名觅美食,邂逅久难忘!", 
          "url": "http-//dpurl.cn/p/+dHQKbRtQA" 
        } 
      ], 
      "has_online_reservation": 0, 
      "online_reservation_url": "" 
    } 
  ] 
} 

用JSONObject解析第一层
"businesses": [  这层用jsonarray解析
里面又嵌套着JSONObject
 "regions": [  这里有嵌套着jsonarray
只要分清楚层次去解析就可以了
用 gson-2.2.4.jar
然后定义类
public class Json
{
public int count;
public String status;
public int total_count;

public List<Businesses> businesses;

}

public class Businesses
{
public String address;
}

自己再一级一写下去
就可以用来直接反射出来了
