对我来说，最简单的方法是使用好的工具来生成所有必需的类。我个人使用这个网站:

http://easywsdl.com/

它支持相当复杂的web服务，并使用ksoap2。

我已经为Android平台创建了一个新的SOAP客户机。它使用一个JAX-WS生成的接口，但到目前为止它只是一个概念验证。

如果你感兴趣，请尝试这个例子和/或在AndroidSOAP上观看源代码。

要从android调用SOAP web服务，请尝试使用此客户端

不要忘记在java构建路径中添加ksoap2-android.jar

public class WsClient {
    private static final String SOAP_ACTION = "somme";
    private static final String OPERATION_NAME = "somme";
    private static final String WSDL_TARGET_NAMESPACE = "http://example.ws";
    private static final String SOAP_ADDRESS = "http://192.168.1.2:8080/axis2/services/Calculatrice?wsdl";

    public String caclculerSomme() {

        String res = null;
        SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
                OPERATION_NAME);
        request.addProperty("a", "5");
        request.addProperty("b", "2");

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);

        try {
            httpTransport.call(SOAP_ACTION, envelope);
            String result = envelope.getResponse().toString();
            res = result;
            System.out.println("############# resull is :" + result);
        } catch (Exception exception) {
            System.out.println("########### ERRER" + exception.getMessage());
        }

        return res;
    }
}

如果可以，选择JSON。Android自带完整的组织。json包

不要忘记在您的项目中添加ksoap2.jar，并添加 AndroidManifest文件中的INTERNET权限

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        try {

            //SoapPrimitive  resultsRequestSOAP = (SoapPrimitive) envelope.getResponse();
            // SoapPrimitive  resultsRequestSOAP = (SoapPrimitive) envelope.getResponse();
            SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;


            lblResult.setText(resultsRequestSOAP.toString());
            System.out.println("Response::"+resultsRequestSOAP.toString());


        } catch (Exception e) {
            System.out.println("Error"+e);
        }

    }
