Android开发可以使用KSoap2可以方便地调用WebService提供的方法,下面的代码实现了通过KSopa2请求WebService查询手机号码归属地的功能:

import java.io.IOException;  
  
import org.ksoap2.SoapEnvelope;  
import org.ksoap2.serialization.SoapObject;  
import org.ksoap2.serialization.SoapSerializationEnvelope;  
import org.ksoap2.transport.HttpTransportSE;  
import org.xmlpull.v1.XmlPullParserException;  
  
import android.os.Bundle;  
import android.os.Handler;  
import android.os.Looper;  
import android.os.Message;  
import android.os.StrictMode;  
import android.app.Activity;  
import android.view.Menu;  
import android.view.View;  
import android.view.View.OnClickListener;  
import android.widget.Button;  
import android.widget.EditText;  
import android.widget.TextView;  
  
/**

public class MainActivity extends Activity {  
    private TextView tv_result;  
    private EditText et_phone;  
    private Button btn_query;  
  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        initView();  
    }  
  
    private void initView() {  
        tv_result = (TextView) findViewById(R.id.result_text);  
        et_phone = (EditText) findViewById(R.id.et);  
        btn_query = (Button) findViewById(R.id.btn_query);  
        btn_query.setOnClickListener(new OnClickListener() {  
  
            @Override  
            public void onClick(View v) {  
                // TODO Auto-generated method stub  
                String phone = et_phone.getText().toString().trim();  
                if ("".equals(phone) || phone.length() < 7) {  
                    et_phone.setText("您输入的手机号码有误");  
                    et_phone.requestFocus();  
                    tv_result.setText("");  
                    return;  
                }  
                getRemoteInfo(phone);  
            }  
        });  
    }  
  
    /** 
     * 查询号码段归属地的方法 
     *  
     * @param phone 
     *            手机号码段 
     */  
    public void getRemoteInfo(final String phone) {  
        new Thread(new Runnable() {  
              
            @Override  
            public void run() {  
                // TODO Auto-generated method stub  
                // 命名空间  
                String nameSpace = "http://WebXml.com.cn/";  
                // 调用方法的名称  
                String methodName = "getMobileCodeInfo";  
                // EndPoint  
                String endPoint = "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";  
                // SOAP Action  
                String soapAction = "http://WebXml.com.cn/getMobileCodeInfo";  
                // 指定WebService的命名空间和调用方法  
                SoapObject soapObject = new SoapObject(nameSpace, methodName);  
                // 设置需要调用WebService接口的两个参数mobileCode UserId  
                soapObject.addProperty("mobileCode", phone);  
                soapObject.addProperty("userId", "");  
                // 生成调用WebService方法调用的soap信息,并且指定Soap版本  
                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(  
                        SoapEnvelope.VER11);  
                envelope.bodyOut = soapObject;  
                // 是否调用DotNet开发的WebService  
                envelope.dotNet = true;  
                envelope.setOutputSoapObject(soapObject);  
                HttpTransportSE transport = new HttpTransportSE(endPoint);  
                try {  
                    transport.call(soapAction, envelope);  
                } catch (IOException e) {  
                    // TODO Auto-generated catch block  
                    e.printStackTrace();  
                } catch (XmlPullParserException e) {  
                    // TODO Auto-generated catch block  
                    e.printStackTrace();  
                }  
                // 获取返回的数据  
                SoapObject object = (SoapObject) envelope.bodyIn;  
                // 获取返回的结果  
                String result = object.getProperty(0).toString();  
                Message message = handler.obtainMessage();  
                message.obj = result;  
                handler.sendMessage(message);  
            }  
        }).start();  
    }  
    private Handler handler = new Handler(){  
        public void handleMessage(android.os.Message msg) {  
            // 将WebService得到的结果返回给TextView  
            tv_result.setText(msg.obj.toString());  
        };  
    };  
} 

Android使用KSoap2调用webService的步骤分为6个:

1. 实例化soapObject对象,指定Soap的命名空间(从相关文档中可以查看WSDL命名空间以及调用方法)

// 命名空间  
String nameSpace = "http://WebXml.com.cn/";  
// 调用方法的名称  
 String methodName = "getMobileCodeInfo";  
 // EndPoint  
String endPoint = "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";  
// SOAP Action  
String soapAction = "http://WebXml.com.cn/getMobileCodeInfo";  
// 指定WebService的命名空间和调用方法  
SoapObject soapObject = new SoapObject(nameSpace, methodName);  

2.假设方法有参数的话,添加调用的方法的参数

// 设置需要调用WebService接口的两个参数mobileCode UserId  
soapObject.addProperty("mobileCode", phone);  
soapObject.addProperty("userId", "");  

3.设置SOAP请求信息(参数部分为SOAP版本号,与自己要调用的SOAP版本必须一致,也就是你导入到工程中的jar相对应的版本)

// 生成调用WebService方法调用的soap信息,并且指定Soap版本  
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(  
            SoapEnvelope.VER11);  
envelope.bodyOut = soapObject;  
// 是否调用DotNet开发的WebService  
envelope.dotNet = true;  
envelope.setOutputSoapObject(soapObject); 

4.构建传输对象,并指定WDSL文档中的URL

HttpTransportSE transport = new HttpTransportSE(endPoint);  

5.调用webService(其中参数为1:命名空间+方法名称,envelope对象);

try {  
    transport.call(soapAction, envelope);  
} catch (IOException e) {  
    // TODO Auto-generated catch block  
    e.printStackTrace();  
} catch (XmlPullParserException e) {  
    // TODO Auto-generated catch block  
    e.printStackTrace();  
} 

6.将返回数据通过Handler对象进行处理:

// 获取返回的数据  
SoapObject object = (SoapObject) envelope.bodyIn;  
// 获取返回的结果  
String result = object.getProperty(0).toString();  
Message message = handler.obtainMessage();  
message.obj = result;  
handler.sendMessage(message); 

下面是处理代码:

    private Handler handler = new Handler(){  
        public void handleMessage(android.os.Message msg) {  
            // 将WebService得到的结果返回给TextView  
            tv_result.setText(msg.obj.toString());  
        };  
    }; 

这样就完成了。
