写项目苦于没有天气数据，从各大开放的API请求数据的话太贵，没办法只能给项目经理说，他二话不说，直接暴力的从中国天气网上爬数据（牛的一批啊），默默崇拜中！！！
先上中国天气网的Uri: http://www.weather.com.cn/

手机查天气
下面就附上代码
public class WeatherUtils {
private final static int timeout = 3 * 1000;
private String url = "http://m.weather.com.cn/d/town/index?lat=${lat}&lon=${lon}";
/**

}
}
最后附上与程序相关的天气图片，这可是我们美工姐姐一个一个切出来，并且把名称对应上的昂。
资源上传到csdn上了，有需要的可以下载去看看
http://download.csdn.net/download/qq_32376365/10207440
用法
lat:维度
lon:经度
这里可以接入定位SDK.
weatherUtils.query(lat, lon)
