我正在与集成的android应用程序上工作。我正在使用fql查询从Facebook获取信息。我的fql方法是

                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对象具有我想要的所有信息。像这样

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

问题是如何将该信息存储到不同的阵列中？

请为此修改一些代码。

回答：

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");
    }
}
