Question

以下是我的JSON。我需要在＆＃34; newsdetail＆＃34;中解析news_title。来自类别列表对象。解析这些数据的正确方法是什么？请帮帮我。

 {"categorylist":[{"process":"news","ncid":"1"","newsdetail":[{"newsid":"604","category":"1","category_title":"","news_title":"just"},{"newsid":"606","category":"1","category_title":"","news_title":"fg"}]},{"process":"news","ncid":"2","newsdetail":[{"newsid":"477","category":"2","category_title":"","news_title":"way},{"newsid":"478","category":"1","category_title":"","news_title":"k"}]}

Answer 1

{"categorylist":[{"process":"news","ncid":"1"" // cannot be double quotes come here. 
,"newsdetail":[{"newsid":"604","category":"1","category_title":"","news_title":"just"},{"newsid":"606","category":"1","category_title":"","news_title":"fg"}]},{"process":"news","ncid":"2","newsdetail":[{"newsid":"477","category":"2","category_title":"","news_title":"way},{"newsid":"478","category":"1","category_title":"","news_title":"k"}]}

你可以使用下面的光标..但你的字符串数据有一些问题

 try {

JSONObject jsonObject = new JSONObject(data);
                    JSONArray category_list = jsonObject.getJSONArray("category_list");
                    for (int i = 0; i < category_list.length() ; i++) {
                        // here you get news title for each news
                        String newsTitle = category_list.getJSONObject(i).getString("news_title");
                    }


                }catch (JSONException e){

                }
