在PC机器java客户端中，需要一些库，比如XFire,Axis2,CXF等等来支持访问WebService，但是这些库并不适合我们资源有限的android手机客户端，做过JAVA ME的人都知道有KSOAP这个第三方的类库，可以帮助我们获取服务器端webService调用，当然KSOAP已经提供了基于android版本的jar包首先下载KSOAP包：ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar包
然后新建android项目
以下分为七个步骤来调用WebService方法：
第一：实例化SoapObject 对象，指定webService的命名空间（从相关WSDL文档中可以查看命名空间），以及调用方法名称。如：
//命名空间
private static final String serviceNameSpace="http://WebXml.com.cn/";
//调用方法(获得支持的城市)
private static final String getSupportCity="getSupportCity";
//实例化SoapObject对象
SoapObject request=new SoapObject(serviceNameSpace, getSupportCity);
第二步：假设方法有参数的话,设置调用方法参数
request.addProperty("参数名称","参数值");
第三步：设置SOAP请求信息(参数部分为SOAP协议版本号，与你要调用的webService中版本号一致):
//获得序列化的Envelope
SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut=request;
第四步：注册Envelope,
(new MarshalBase64()).register(envelope);
第五步：构建传输对象，并指明WSDL文档URL：
//请求URL
private static final String serviceURL="http://www.webxml.com.cn/webservices/weatherwebservice.asmx";
//Android传输对象
AndroidHttpTransport transport=new AndroidHttpTransport(serviceURL);
transport.debug=true;
第六步：调用WebService(其中参数为1：命名空间+方法名称，2：Envelope对象):
transport.call(serviceNameSpace+getWeatherbyCityName, envelope);
第七步：解析返回数据：
if(envelope.getResponse()!=null){
return parse(envelope.bodyIn.toString());
}
/**************
* 解析XML
* @param str
* @return
*/
private static List<String> parse(String str){
String temp;
List<String> list=new ArrayList<String>();
if(str!=null && str.length()>0){
int start=str.indexOf("string");
int end=str.lastIndexOf(";");
temp=str.substring(start, end-3);
String []test=temp.split(";");
for(int i=0;i<test.length;i++){
if(i==0){
temp=test[i].substring(7);
}else{
temp=test[i].substring(8);
}
int index=temp.indexOf(",");
list.add(temp.substring(0, index));
}
}
return list;
}
这样就成功啦。那么现在我们就来测试下吧，这里有个地址提供webService天气预报的服务的，我这里只提供获取城市列表：
//命名空间
private static final String serviceNameSpace="http://WebXml.com.cn/";
//请求URL
private static final String serviceURL="http://www.webxml.com.cn/webservices/weatherwebservice.asmx";
//调用方法(获得支持的城市)
private static final String getSupportCity="getSupportCity";
//调用城市的方法(需要带参数)
private static final String getWeatherbyCityName="getWeatherbyCityName";
//调用省或者直辖市的方法(获得支持的省份或直辖市)
private static final String getSupportProvince="getSupportProvince";
然后你可以在浏览器中输入地址（WSDL）：serviceURL,你会看到一些可供调用的方法：
我们选择获取国内外主要城市或者省份的方法吧：getSupportProvice,然后调用，你会发现浏览器返回给我们的是xml文档：
<?xml version="1.0" encoding="utf-8" ?>
- <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://WebXml.com.cn/">
<string>直辖市</string>
<string>特别行政区</string>
<string>黑龙江</string>
<string>吉林</string>
<string>辽宁</string>
<string>内蒙古</string>
<string>河北</string>
<string>河南</string>
<string>山东</string>
<string>山西</string>
<string>江苏</string>
<string>安徽</string>
<string>陕西</string>
<string>宁夏</string>
<string>甘肃</string>
<string>青海</string>
<string>湖北</string>
<string>湖南</string>
<string>浙江</string>
<string>江西</string>
<string>福建</string>
<string>贵州</string>
<string>四川</string>
<string>广东</string>
<string>广西</string>
<string>云南</string>
<string>海南</string>
<string>新疆</string>
<string>西藏</string>
<string>台湾</string>
<string>亚洲</string>
<string>欧洲</string>
<string>非洲</string>
<string>北美洲</string>
<string>南美洲</string>
<string>大洋洲</string>
</ArrayOfString>
我们可以用 listview来显示：
那么下面我将给出全部代码：

//需要调用的方法名(获得本天气预报Web Services支持的城市信息,根据省份查询城市集合：带参数)
private static final String getSupportCity="getSupportCity";
//根据城市或地区名称查询获得未来三天内天气情况、现在的天气实况、天气和生活指数
