android - 将复杂的 JSON 对象解析为 Java 对象并添加到 recyclerview

Question

onResponse(JSONObject response)我想从服务器获取数据并将其解析到回收站 View 。我在 stackoverflow 上看到了很多答案，但找不到适合我的复杂 JSON 数据的任何合适的解决方案。我正在使用 volley 库，GSON 可能是映射我的 Java 对象的正确方法。请告诉我从这个 json 获取响应的正确方法。我只想使用“title”、“body”和“createdAt”的信息。以下是我在授权 token 的帮助下收到的 json 的一部分。
