它将返回一个对象。在 JSON 对象中，我也有 JSON 数组。

请帮助我如何使用 GSON 反序列化该对象。

Answer 1

只需创建一个类：

public class Response {
    private status int;
    private String msg;
    private double user_lat;
    ...
    private Poi[] poi_list;
    ...
}

public class Poi {
    private long poi_id;
    private String poi_name;
    ...
}

然后你就可以了

Response response = new Gson().fromJson(jsonString, Response.class);
