1.将ksoap2-android-assembly-3.0.0-jar-with-dependencies.jar包添加到Android项目的libs目录下
2.Web Service的工具类WebServiceHelper

[java] view plaincopy
import java.util.HashMap;  
import java.util.Map.Entry;  
import org.ksoap2.SoapEnvelope;  
import org.ksoap2.serialization.SoapObject;  
import org.ksoap2.serialization.SoapSerializationEnvelope;  
import org.ksoap2.transport.HttpTransportSE;  
import android.annotation.SuppressLint;  
import android.os.Build;  
import android.os.StrictMode;  
/** 
 * 访问Web Service的工具类 
 * @author jCuckoo 
 *  
 */  
@SuppressLint("NewApi")  
public class WebServiceHelper {  
    static {  
        if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.ICE_CREAM_SANDWICH){  
            // 4.0以后需要加入下列两行代码，才可以访问Web Service  
            StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()  
                    .detectDiskReads().detectDiskWrites().detectNetwork()  
                    .penaltyLog().build());  
  
            StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()  
                    .detectLeakedSqlLiteObjects().detectLeakedClosableObjects()  
                    .penaltyLog().penaltyDeath().build());  
        }  
        //4.0以前版本不需要以上设置  
    }  
    /** 
     * @param url          web service路径 
     * @param nameSpace    web service名称空间 
     * @param methodName   web service方法名称 
     * @param params       web service方法参数 
     */  
    public static SoapObject getSoapObject(String serviceName,  
            String methodName, String soapAction, HashMap<String, Object> params) {  
        String URL = "http://192.168.1.89:8080/MyWebService/webservice/"+ serviceName + "?wsdl";  
        String NAMESPACE = "http://webservice.dh.com/";// 名称空间，服务器端生成的namespace属性值  
        String METHOD_NAME = methodName;  
        String SOAP_ACTION = soapAction;  
  
        SoapObject soap = null;  
        try {  
            SoapObject rpc = new SoapObject(NAMESPACE, METHOD_NAME);  
            if (params != null && params.size() > 0) {  
                for (Entry<String, Object> item : params.entrySet()) {  
                    rpc.addProperty(item.getKey(), item.getValue().toString());  
                }  
            }  
  
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);  
            envelope.bodyOut = rpc;  
            envelope.dotNet = false;// true--net; false--java;  
            envelope.setOutputSoapObject(rpc);  
  
            HttpTransportSE ht = new HttpTransportSE(URL);  
            ht.debug = true;  
            ht.call(SOAP_ACTION, envelope);  
            try {  
                soap = (SoapObject) envelope.getResponse();  
            } catch (Exception e) {  
                soap = (SoapObject) envelope.bodyIn;  
            }  
        } catch (Exception ex) {  
            ex.printStackTrace();  
        }  
        return soap;  
    }  
}  

3.创建service层LoginService

[java] view plaincopy
import java.util.HashMap;  
import org.ksoap2.serialization.SoapObject;  
import android.content.Context;  
import android.widget.Toast;  
  
import com.dh.util.WebServiceHelper;  
  
public class LoginService {  
    public void login(Context context,String userName,String userPwd){  
        HashMap<String, Object> paramsMap = new HashMap<String, Object>();  
        paramsMap.put("userName", userName);  
        paramsMap.put("userPwd", userPwd);  
                                                              // 服务的名称    方法名    soapAction--null   参数数据  
        SoapObject soapOjbect = WebServiceHelper.getSoapObject("UserService", "checkUser", null, paramsMap);  
        if(soapOjbect!=null){  
            Toast.makeText(context, soapOjbect.getPropertyAsString(0), Toast.LENGTH_LONG).show();  
        }  
    }  
}  

4.设计布局界面activity_main.xml

[html] view plaincopy
<?xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    xmlns:tools="http://schemas.android.com/tools"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent"  
    android:paddingBottom="@dimen/activity_vertical_margin"  
    android:paddingLeft="@dimen/activity_horizontal_margin"  
    android:paddingRight="@dimen/activity_horizontal_margin"  
    android:paddingTop="@dimen/activity_vertical_margin"  
    tools:context=".MainActivity"   
    android:orientation="vertical">  
    <LinearLayout android:id="@+id/Layout_top"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:orientation="horizontal">  
        <TextView android:text="用户名："  
            android:layout_width="fill_parent"  
            android:layout_height="wrap_content"/>  
        <EditText android:id="@+id/userName"  
            android:layout_width="fill_parent"  
            android:layout_height="wrap_content"/>  
    </LinearLayout>  
    <LinearLayout android:id="@+id/Layout_middle"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:orientation="horizontal">  
        <TextView android:text="密码："  
            android:layout_width="fill_parent"  
            android:layout_height="wrap_content"/>  
        <EditText android:id="@+id/userPwd"  
            android:layout_width="fill_parent"  
            android:layout_height="wrap_content"/>  
    </LinearLayout>  
    <Button android:id="@+id/login_Button"  
        android:text="登陆"  
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content" />  
</LinearLayout>  

5.编写程序主界面MainActivity

[java] view plaincopy
import android.app.Activity;  
import android.os.Bundle;  
import android.view.Menu;  
import android.view.View;  
import android.view.View.OnClickListener;  
import android.widget.Button;  
import android.widget.EditText;  
import android.widget.Toast;  
  
import com.dh.service.LoginService;  
  
public class MainActivity extends Activity {  
    private EditText userNameEditText;  
    private EditText userPwdEditText;  
    private Button loginButton;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        userNameEditText=(EditText) findViewById(R.id.userName);  
        userPwdEditText=(EditText)findViewById(R.id.userPwd);  
        loginButton=(Button) findViewById(R.id.login_Button);  
        loginButton.setOnClickListener(new OnClickListener() {  
              
            @Override  
            public void onClick(View arg0) {  
                String userName=userNameEditText.getText().toString();  
                String userPwd=userPwdEditText.getText().toString();  
                if("".equals(userName)&&"".equals(userPwd)){  
                    Toast.makeText(MainActivity.this, "用户名或密码不能为空", Toast.LENGTH_LONG).show();  
                }  
                LoginService loginService=new LoginService();  
                loginService.login(getApplicationContext(), userName, userPwd);  
                  
            }  
        });  
    }  
}  

6.在AndroidManifest.xml中设定网络访问权限

[html] view plaincopy
<!-- 设置使用web service等的权限 -->  
    <uses-permission android:name="android.permission.INTERNET" />
