添加ksoap2-android-assembly-3.6.3-jar-with-dependencies.jar包

创建KsoapHelper类 

public class KsoapHelper {
    public static int timeOut = 30000;
    public static String webServiceUrl;
    public static String nameSpace;
    public static int soapVersion = 120;

    private KsoapHelper() {
    }

    public static void initKsoapHelper(String _webServiceUrl, String _nameSpace) {
        initKsoapHelper(timeOut, _webServiceUrl, _nameSpace, soapVersion);
    }

    public static void initKsoapHelper(String _webServiceUrl, String _nameSpace, int _version) {
        initKsoapHelper(timeOut, _webServiceUrl, _nameSpace, _version);
    }

    public static void initKsoapHelper(int _timeOut, String _webServiceUrl, String _nameSpace, int _version) {
        nameSpace = _nameSpace;
        webServiceUrl = _webServiceUrl;
        timeOut = _timeOut;
        soapVersion = _version;
    }

    public static SoapObject GetSoapObject(String methodName) {
        SoapObject object = new SoapObject(nameSpace, methodName);
        return object;
    }

    public static SoapObject GetSoapObject(String nameSpace, String methodName) {
        SoapObject object = new SoapObject(nameSpace, methodName);
        return object;
    }

    public static Object GetResult(SoapObject object, boolean isSimple) throws IOException, XmlPullParserException {
        SoapSerializationEnvelope sSEnvelope = new SoapSerializationEnvelope(120);
        sSEnvelope.bodyOut = object;
        sSEnvelope.dotNet = true;
        HttpTransportSE httpTransSE = new HttpTransportSE(webServiceUrl, timeOut);
        httpTransSE.debug = true;
        httpTransSE.call((String)null, sSEnvelope);
        SoapObject result;
        if (isSimple) {
            result = null;
            Object simpleResult = sSEnvelope.getResponse();
            return simpleResult.toString();
        } else {
            result = null;
            result = (SoapObject)sSEnvelope.getResponse();
            SoapObject childs = (SoapObject)result.getProperty(1);
            return (SoapObject)childs.getProperty(0);
        }
    }
}

编写MainActivity类，橙色部分根据自己情况更改

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private String WEBSERVICE_URL;
    private String NAMESPACE;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
    }
    /**
     * 初始化
     */
    private void initView() {
 WEBSERVICE_URL = "http://192.168.200.185:8090/UserInfoManagement.asmx?wsdl";
   NAMESPACE = "http://tempuri.org/";
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()){
            case R.id.btn_enter:
                Login();
                break;
        }
    }
  　　 public void Login(){
 KsoapHelper.initKsoapHelper(WEBSERVICE_URL, NAMESPACE);
SoapObject request = KsoapHelper.GetSoapObject("UserCheck");
    request.addProperty("UserID", et_name.getText().toString());
        request.addProperty("Password", et_pwd.getText().toString());
        try {
            String sCheckuser=(String) KsoapHelper.GetResult(request, true);
        } catch (Exception var) {
            return ;
        }
    }
}
