]Android通过调用Webservice实现天气预报

通过这一篇文章WebService的读书笔记对Web Service的认识，现在来写一个小应用Android通过调用Webservice实现天气预报来加强对Web Srevice的学习

在开发天气预报的Android应用之前，首先需要找到一个可以对外提供天气预报的Web Service,通过搜索发现站点http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx可以对外提供天气预报的Web Service,因此程序会调用此站点的Web Service来实现天气预报。(注意：如果该站点的天气预报Web Service服务已经停止，那么本程序将无法正常调用Web Service，那么天气预报的功能自然也就失效啦)

好啦，现在开始step by step地实现该应用程序。

step1:新建Android项目MyWeather

step2:获取并使用KSOAP包

在Android SDK中并没有提供调用WebService的库，因此，需要使用第三方的SDK来调用WebService。PC版本的WebService库非常丰富，但这些对Android来说过于庞大。适合手机的WebService客户端的SDK有一些，比较常用的是KSOAP2。

KSOAP2 地址：http://code.google.com/p/ksoap2-android/

我下载的最新的是： ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar

选择我们的项目，右键菜单中 Build Path –> Add External Archives… 增加这个下载的包

step3:设计应用的UI界面 /res/layout/main.xml

7. <stringname="city">城市</string>

step3:编写调用Web Service的工具类 cn.roco.weather.WebServiceUtil.java

因为本程序主要需要调用如下三个Web Service操作：

a.获取省份：getRegionProvince方法

b.根据省份获取城市：getSupportCityString方法

c.根据城市获取天气：getWeather方法

为了让应用界面更加美观，可以访问http://www.webxml.com.cn/images/weather.zip下载各种天气图标，可以使用这些天气图标来美化应用。
