嗨，我收到了来自服务器的 JSON 响应，如下所示。我想知道如何在我的课堂上使用这个 JSON 类作为 GSON 和 POJO。我无法从帖子中获得价值。

我如何为它创建 POJO 类并从这个 POJO 类中获取价值。任何人都可以有想法从中制作 POJO 类，我将在我的应用程序中访问值。

先感谢您。

在这里，我的 POJO 类我无法从中获取值，我如何使它可以用来访问值并在我的应用程序中使用它。

  }

  void setId(int id){this.of_id=id;}
  void setTitle(String title){this.of_title=title;}
  ....//do this for all the class variables
  int getId(){return this.of_id;}
  String getTitle(){return this.of_title;}
  ....//do this for all the class variables
}

// 您可以将 PostData 添加到列表中

 ArrayList<PostData> offerList = new ArrayList<PostData>();

 JSONObject job = new JSONObject(jsonResponseString);
 JSONArray jarr = job.getJSONArray("offers");
 for(int i=0;i<jarr.length();i++)
{
   JSONObject post = jarr.getJSONObject(i);
   PostData offer = new PostData();
   offer.setId(post.getJSONObject("of_id");
   offer.setTitle(post.getJSONObject("of_title");
   //...set all the json object

  offerList.add(offer);
}
