JSON數據解析

JSON返回示例：

{
    "resultcode":"200",
    "reason":"Successed!",
    "result":{
        "lat":"39.915065193348",
        "lng":"116.40389843345",
        "type":"1",
        "address":"北京市東城區中華路甲10號",
        "business":"天安門",
        "citycode":131
    }
}

JSON解析如下：

//以下是發送網絡請求JSON數據
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url.toString());
HttpResponse httpResponse = httpClient.execute(httpGet);
            if(httpResponse.getStatusLine().getStatusCode()==200){
    HttpEntity entity = httpResponse.getEntity();
    String response = EntityUtils.toString(entity, "utf-8");
    //以下是對JSON數據進行解析                    
    JSONObject jsonObject = new JSONObject(response);
    JSONObject result = jsonObject.getJSONObject("result");         
    String location= result.getString("address");
}

JSON返回示例：
{“response”:{“data”:[{“address”:”南京市遊樂園”,”province”:”江蘇”,”district”:”玄武區”,”city”:”南京”}]},”status”:”ok”}

JSON解析如下：

JSONObject  dataJson=new JSONObject("你的Json數據“);
JSONObject  response=dataJson.getJSONObject("response");
JSONArray data=response.getJSONArray("data");
JSONObject info=data.getJSONObject(0);
String province=info.getString("province");
String city=info.getString("city");
String district=info.getString("district");
String address=info.getString("address");
System.out.println(province+city+district+address);
