android - 无法获取摄氏温度

Question

我知道以前有人问过这类问题……但我想不通……我读过这个操作系统问题 link1和 link2

我正在开发一个天气预报应用程序，为此我正在使用 yahoo weather api。

我正在使用此 url 进行响应

 String url = "https://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast where woeid="+woeid+
                " and u='c'&format=xml&env=store://datatables.org/alltableswithkeys";

        url = url.replace(" ","%20");

我收到了这个回复

我在控制台上尝试了你的位置，如果你请求这些项目，你会在预报和当前条件中获得摄氏度。我试过:

select item.forecast from weather.forecast where woeid = 2295402 and u='c'

返回以摄氏度为单位的 10 天预报。网址将是

https://query.yahooapis.com/v1/public/yql?q=select%20item.forecast%20from%20weather.forecast%20where%20woeid%20%3D%202295402%20and%20u%3D'c'&format=xml&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys

将 item.forecast 更改为 item.conditions 与当前条件相同。我再次尝试选择 *，它给出了华氏度错误。也许对这些项目使用单独的查询可以帮助您？
