Android Call WebService

android端与服务器交互 一般情况下,我们可以使用SOCKET,HTTP(GET,POST)等,我们也可以使用另外一种方式,webservice, 

它是一种基于SAOP协议的远程调用标准，通过webservice可以将不同操作系统平台，不同语言，不同技术整合到一起。说白了就是一种中间件技术. 

我们在android客户端中，有时需要一些库，比如XFire,Axis2,CXF等等来支持访问WebService，由于android sdk等并没有提供这些库,所以并不适合我们资源有限的android手机客户端，这里有KSOAP这个第三方的类库，可以帮助我们获取服务器端webService调用，KSOAP已经提供了基于android版本的jar包. 

先下载KSOAP包：ksoap2-android-assembly-2.5.4-jar-with-dependencies.jar包 

然后新建一个android项目：并把下载的KSOAP包放在android项目的lib目录下：右键->build path->configure build path--选择Libraries，如图：

以下分为七个步骤来调用WebService方法： 

第一：实例化SoapObject 对象，指定webService的命名空间（从相关WSDL文档中可以查看命名空间），以及调用方法名称。

public final static String NAMESPACE = "http://tempuri.org/"; 

public static String wsdl ="http://jinhesoft.com/Service1.asmx"; 

private final static String defaultAddress ="jinhesoft.com"; 
private final static String defaultPage = "service1.asmx"; 
public final static String CONFIG_PATH = "/data/data/org.DigitalCM/DigitalCMWebserviceConfig.dat"; 

第二步：假设方法有参数的话,设置调用方法参数

request.addProperty("参数名称","参数值"); 

第三步：设置SOAP请求信息(参数部分为SOAP协议版本号，与你要调用的webService中版本号一致):

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope( 
    SoapEnvelope.VER10); 
  envelope.setOutputSoapObject(request); 

  // envelope.bodyOut = request; 

第四步：构建传输对象，并指明WSDL文档URL：

HttpTransportSE ht = new HttpTransportSE(wsdl); 

第五步：调用WebService(其中参数为1：命名空间+方法名称，2：Envelope对象):

ht.call(SOAP_ACTION, envelope);// 调用webservice（其中参数一SOAP_ACTION为命名空间+方法名，参数二为envelope） 

第六步：解析返回数据

resultObject = envelope.getResponse();

第7步：使用getResponse方法获得WebService方法的返回结果

原理和步骤过程了解后，我们下面结合具体项目实例给大家分享下,我们还是以之前的一篇文章: 登陆界面软件自动更新功能的实现http://blog.csdn.net/jindegegesun/article/details/7232779 

为例进行,简化更改一个登陆过程。 

1、新建一个登陆的布局界面

                    .setPositiveButton(R.string.OK_text,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,

                    .setNegativeButton(R.string.cancel_text,
                            new DialogInterface.OnClickListener() {

        }
        return super.onCreateDialog(id);
    }
    

}

package cn.jindegegesun.activity;


import android.app.Activity;
import android.os.Bundle;
import android.view.Window;





public class Main extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);//设置全屏
        setContentView(R.layout.main);

        


    }
}

第四步：添加程序所用的权限：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="cn.jindegegesun.activity"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="7" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".DigitalCity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
         <activity
            android:label="@string/login_name"
            android:name="cn.jindegegesun.activity.Main" >
        </activity>
    </application>
    <uses-permission android:name="android.permission.INTERNET" />
</manifest>

注意：在第一个DigitalCity .activity的login()方法调用了webservice返回的数据，先贴出代码；

以上的红色字体部分就是具体调用webservice的具体步骤，最后一步，也就是第六步将会提供结果给调用webservice的方法，然后login()方法将通过 
result = WSUtil.getSoapObjectByCallingWS( 
         WebServiceConfig.NAMESPACE, "login", params, 
         WebServiceConfig.wsdl); 

得到第六步返回的结果。 

当返回的结果与登陆界面输入的帐号和密码匹配后，登陆就成功了。 



当然与服务器交互，这里还需要写接口,关键是其中的sql语句，我是在visual studio 2008上用c#写的一个login接口，如下：

    [WebMethod(Description = "Android 接口： 登陆 userName 用户名 userPwd 用户密码")]  
            public DataSet login(string userName, string userPwd)  
            {  
                DataSet ds = null;  
      
                string strSql = string.Format("select userid, username, password, deptid, realname, tel, email, usermemo, starttime, endtime, mapid, dwid, zw, deptname, purviewmid, dwmc from V_USERS t where t.username = '{0}' and t.password='{1}'", userName, userPwd);  
                try  
                {  
                    RetStrSql(strSql);  
                    ds = RetDataSet();  
                    return ds;  
                }  
                catch (Exception ex)  
                {  
                    //throw new Exception(ex.Message);  
                    return null;  
      
                }  
            }
