Android中json數據手動解析方式

json數據手動解析：

每個大括號都是一個JSONObject

中括號爲集合（JSONArray）

代碼示例：

一段ｊｓｏｎ數據：

{

    "reason": "成功的返回",

    "result": {

        "stat": "1",

        "data": [

            {

                "uniquekey": "6de190ba8b7e354806c9d827c6e0d6f7",

                "title": "美容業亂象調查:女子1萬整形被整殘 花百萬修復",

                "date": "2017-03-22 13:29",

                "category": "頭條",

                "author_name": "齊魯網",

                "url": "http://mini.eastday.com/mobile/170322132951431.html",

                "thumbnail_pic_s": "http://00.imgmini.eastday.com/mobile/20170322/20170322132951_98974bebe08b1afb4bd56c4834fef517_1_mwpm_03200403.jpeg",

                "thumbnail_pic_s02": "http://00.imgmini.eastday.com/mobile/20170322/20170322132951_98974bebe08b1afb4bd56c4834fef517_2_mwpm_03200403.jpeg",

                "thumbnail_pic_s03": "http://00.imgmini.eastday.com/mobile/20170322/20170322132951_98974bebe08b1afb4bd56c4834fef517_3_mwpm_03200403.jpeg"

            },

            {

                "uniquekey": "a3106bde1776232b407a355084bce36a",

                "title": "融合探索闖\u201c江湖\u201d",

                "date": "2017-03-22 14:16",

                "category": "頭條",

                "author_name": "人民日報中央廚房",

                "url": "http://mini.eastday.com/mobile/170322141636146.html",

                "thumbnail_pic_s": "http://09.imgmini.eastday.com/mobile/20170322/20170322141636_1673587ab3b1064924d0243610e73f64_1_mwpm_03200403.jpeg"

            }］

｝

解析步驟：

１．遇到大括號就getJSONObject

２．遇到中括號就getJSONArray，想獲取JSONArray集合中的元素，就給下標就行，下標從零開始計算。

//s爲json數據字符串類型（String）
JSONObject jsonObject = new JSONObject(s);
JSONObject result = jsonObject.getJSONObject("result");
JSONArray data = result.getJSONArray("data");
JSONObject jsonObject1 = data.getJSONObject(2);
String uniquekey = jsonObject1.getString("uniquekey");
String title = jsonObject1.getString("title");
String date = jsonObject1.getString("date");
String category = jsonObject1.getString("category");
String author_name = jsonObject1.getString("author_name");
String url1 = jsonObject1.getString("url");
String thumbnail_pic_s = jsonObject1.getString("thumbnail_pic_s");
