Android简单版天气预报源码，整体重构（第四步）

找到一个比较好用的天气数据API

http://wthrcdn.etouch.cn/weather_mini?city=深圳@H_301_11@http://wthrcdn.etouch.cn/weather_mini?citykey=101280601

快春节了，更新一下，说是第四步，也不是哈哈哈哈

项目源码地址@H_301_11@https://github.com/LGH-cmd/weather-report

前端UI跟之前差不多

改动了API，当然要重新写GSON

也就依葫芦画瓢，就不展示了@H_301_11@MainActivity 大部分实现也就是得到数据后展示到页面

整体代码

不同点，在预报中用的是ListVIEw展示@H_301_11@也不是很难实现。与之前有相同之处，可参考前面，完整代码已经在GitHub上
