如何从JSON对象的数据？ [英] how to get data from Json object?

问题描述

我工作的一个Android应用程序是与Facebook集成。我使用FQL查询获取来自Facebook的信息。我FQL方法

 无效runfql（）{
                字符串fqlQuery =SELECT UID，名称，pic_small，生日从用户其中UID IN+
                  （SELECT UID2从朋友哪里UID1 =我（））;
                捆绑PARAMS =新包（）;
                params.putString（Q，fqlQuery）;
                会话会话= Session.getActiveSession（）;
                请求请求=新的请求（会话，
                / FQL
                参数，可以
                HttpMethod.GET，
                新Request.Callback（）{
                        公共无效onCompleted（响应响应）{

                        JSONObject的myjson = response.getGraphObject（）getInnerJSONObject（）。
                        Log.d（ResultResultResult：，+ myjson）;
                        }
                    }）;
                    Request.executeBatchAsync（要求）;

                }
 

myjson对象的所有信息我想要的。像这样

  {数据：[{UID：536089174，生日：7月22日，名：奥斯曼阿斯拉姆谢赫}，{UID： 581379174，生日：7月26日，名：阿马尔·哈立德}
 

问题是如何把信息存储到不同的阵列？

请正确一些code用于这一目的。

解决方案

 字符串jsonString = yourstring;
JSONObject的jsonResult =新的JSONObject（jsonString）;
JSONArray数据= jsonResult.getJSONArray（数据）;
如果（数据！= NULL）{
    的String []的名称=新的String [data.length（）];
    的String []生日=新的String [data.length（）];
    的for（int i = 0; I＆LT; data.length（）;我++）{
        生日[I] = data.getString（生日）;
        名称[I] = data.getString（姓名）;
    }
}

                void runfql(){
                String fqlQuery = "SELECT uid, name, pic_small,birthday FROM user WHERE uid IN " +
                  "(SELECT uid2 FROM friend WHERE uid1 = me() )";
                Bundle params = new Bundle();
                params.putString("q", fqlQuery);
                Session session = Session.getActiveSession();
                Request request = new Request(session,
                "/fql",                         
                params,                         
                HttpMethod.GET,                 
                new Request.Callback(){         
                        public void onCompleted(Response response) {

                        JSONObject myjson=response.getGraphObject().getInnerJSONObject();
                        Log.d("ResultResultResult: " ,""+myjson);                           
                        }                  
                    }); 
                    Request.executeBatchAsync(request);  

                } 

myjson object has all info i want. like this

 {"data":[{"uid":536089174,"birthday":"July 22","name":"Usman Aslam Sheikh"},{"uid":581379174,"birthday":"July 26","name":"Ammar Khalid"}

question is how to store that information into different arrays??

please right some code for this purpose.?

解决方案

String jsonString = yourstring;
JSONObject jsonResult = new JSONObject(jsonString);
JSONArray data = jsonResult.getJSONArray("data");
if(data != null) {
    String[] names = new String[data.length()];
    String[] birthdays = new String[data.length()];
    for(int i = 0 ; i < data.length() ; i++) {
        birthdays[i] = data.getString("birthday");
        names[i] = data.getString("name");
    }
}
