如何检索json数组内部的对象值

Question

我已经完成了使用fragment的编码。下面

这个我homeFragment

res = out.toString(); 
         JSONArray arrJsonArray=new JSONArray(res); 
         for (int i = 0; i < arrJsonArray.length(); i++) { 
          JSONObject object = arrJsonArray.getJSONObject(i); 
          Data data=new Data(); 
          data.setName(object.getString("title")); 
          data.setMsg(object.getString("slug")); 
          /* for abouve code i am getting data for below code i am not able to retrive the data*/ 
          object.getJSONObject("offer_shop_details"); 
          data.setOffer(object.getString("time_field_from_sunday")); 
          itemList.add(data); 
         } 

是我的JSON。我是jsonArray

我给了我的json的一个数组元素。

我需要获取“offer_shop_details”中的数据，以上是我的逻辑。帮助我找到正确的答案。

下面的json如果你验证它会告诉无效。因为我只给了它的一部分。

Answer 1

您的JSON字符串的根是一个JSONObject因此用它来分析你的JSON，然后用getJSONArray让你的JSON数组：

res = out.toString(); 

JSONObject rootJsonObject = new JSONObject(res); 

// And then you can access to your array 
JSONArray arrJsonArray= jsonObject.getJSONArray(rootJsonObject);
