我要做一个基于
Android studio的多城市切换+短时预警天气预报app，我的天气API是在https://www
.seniverse
.com/products这个网站中获取的，其中我的密钥（私钥）是SH8NroqLlNNwwg323，但是我运行之后没有获取到实时数据，我要怎么做，请给我完整代码及完善步骤
这个是我的接口ApiService代码
package com

// 图片中的API密钥（公钥+私钥）
String PUBLIC_KEY = "PVKLD84OHMbGx9iQG";
String PRIVATE_KEY = "SH8NroqLINNwg323";
/**

// 7天预报响应模型

本文探讨了在代码中调用setRefreshing(false)后SwipeRefreshLayout仍不停止刷新的原因及解决方案，包括通过debug检查代码执行路径、使用post方式刷新、调整进度条位置等方法。
