基于Android的WebService开发例子

WebService提供服务网站：http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx

开发时需要结合网站提供的Soap的请求示例，例如请求示例：

POST /WebServices/WeatherWS.asmx HTTP/1.1Host: webservice.webxml.com.cnContent-Type: text/xml; charset=utf-8Content-Length: lengthSOAPAction: "http://WebXml.com.cn/getRegionProvince"<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">  <soap:Body>    <getRegionProvince xmlns="http://WebXml.com.cn/" />  </soap:Body></soap:Envelope>

Activity如下：
