android客户端与服务器交互数据（基于SAOP协议的远程调用标准，通过webservice可以将不同操作系统平台，不同语言，不同技术整合）

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：
