Android访问WebService-CXF步骤

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 ServiceStrictMode.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;@Overrideprotected 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() {@Overridepublic 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" />
