1、添加网络访问权限在AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET"/>

2、加入soap的jia包ksoap2-android-assembly-2.5.4-jar-with-dependencies.jar

3、 创建字段

// 名空间
    private static final String NAMESPACE   = "http://WebXml.com.cn/";
    // 网址
    private static String  URL      = "http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx";
    // 方法名
    private static final String METHOD_NAME = "getWeather";
    // SOAPACTION
    private static String  SOAP_ACTION = "http://WebXml.com.cn/getWeather";

4、 获取Soap对象并设置传送参数值

SoapObject rpc = new SoapObject(NAMESPACE, METHOD_NAME);
    rpc.addProperty("theCityCode", cityName);

5、 创建SoapSerializationEnvelope对象

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.bodyOut = rpc;
    envelope.dotNet = true;
    envelope.setOutputSoapObject(rpc);
    //其中SoapEnvelope.VER11是指SOAP 1.1，

6、创建HttpTransportsSE对象

HttpTransportSE ht = new HttpTransportSE(URL);
    ht.debug = true;
    //对于部分不规范的webService需要使用ht.call(null, envelope);
     ht.call(SOAP_ACTION, envelope);

7、获得WebService方法的返回结果

方法一：

detail =(SoapObject) envelope.getResponse();

方法二：

SoapObject result = (SoapObject)envelope.bodyIn;

detail = (SoapObject) result.getProperty("getWeatherbyCityNameResult");

8、解析SoapObject对象

if(envelope.getResponse()!=null)\{  
SoapObject detail =(SoapObject) envelope.bodyIn;

for (int i = 0; i < detail.getPropertyCount(); i++) \{

System.out.println("detail.getProperty(" + i + ")" + detail.getProperty(i));

可测试的 webservice服务

[http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx][http_webservice.webxml.com.cn_WebServices_WeatherWS.asmx]

页面中有以下信息：

getWeather

获得天气预报数据

输入参数：城市/地区ID或名称，返回数据：一维字符串数组

点击getWeather

[http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx?op=getWeather][http_webservice.webxml.com.cn_WebServices_WeatherWS.asmx_op_getWeather]

从上述页面可以获取以下信息：

SOAPAction: "http://WebXml.com.cn/getWeather"
    <getWeather xmlns="http://WebXml.com.cn/">
    其中xmlns就是NAMESPACE值以及传送参数名theCityCode
