Android访问WebService-CXF步骤

文章来源：http://blog.csdn.net/guoquanyou/article/details/9290609

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

 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

 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

 <?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

 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

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