[置顶] android 调用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：
![[置顶] android 调用webservice_第1张图片](http://img.e-com-net.com/image/info5/e759b43a2db94dfe8765afbbc90622a7.png)
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://XXsoft.com/Service1.asmx";
private final static String defaultAddress ="XXsoft.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
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/exit_text" >

</LinearLayout>
</RelativeLayout>
第二步：建立登陆的Activity
package cn.jindegegesun.activity;
import java.util.HashMap;

public class DigitalCity extends ContextActivity implements OnClickListener {

private Button login = null;
private Button exit = null;
private EditText userCode = null;
private EditText password = null;
private CheckBox rememberpwd = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
findViews();
loadConfig();
setOnClickListener();
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
public void setOnClickListener() {
/* 为 Button 注册点击事件监听对象，采用了匿名内部类的方式。 */
login.setOnClickListener(new View.OnClickListener() {
@Override

}
}
);
/* 为 Button 注册点击事件监听对象，采用了匿名内部类的方式。 */

@SuppressWarnings("static-access")

.toString()));
Map<String, Object> params = new HashMap<String, Object>();

SoapObject result = null;
try {

//log("SSSSSSSSSSSS");
} catch (Exception ex) {
showDialog(DIALOG_CONNECT_ERROR);
Log.e("Exception", ex.getMessage());
}
if (result == null) {
loginFailed();
}
WSObjectUtil wsObjectUtil = new WSObjectUtil();
SoapObject dataSet = null;
try {
dataSet = wsObjectUtil.getDataSetObject(result);
} catch (Exception e) {
loginFailed();
}

}
List<Map<String, Object>> rowMapList = WSObjectMapUtil

}
private Boolean validate(String user_code, String password) {

showDialog(DIALOG_USER_PWD_EMPTY);
return false;

return true;
}
public void loadConfig() {

String username = properties.getProperty("username");
String pwd = properties.getProperty("password");

}

}
private void loginFailed() {

}

}
@Override

.setPositiveButton(R.string.OK_text,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int arg1) {
// TODO Auto-generated method stub

}
}).show();
case LoginActions.DIALOG_CONNECT_ERROR:
return new AlertDialog.Builder(this)

.setMessage(R.string.connection_error)
.setPositiveButton(R.string.OK_text,
new DialogInterface.OnClickListener() {
@Override

new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
dialog.cancel();
}
}).show();
}
return super.onCreateDialog(id);
}
}
第三步：新建一个登陆进入后的布局文件main.xml以及Main.Activity，这个类和界面都很简单
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="hello,jindegege!"/>"
</LinearLayout>
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;
}
}
好的，基本就是这样，贴上代码共享地址：http://download.csdn.net/detail/jindegegesun/4070721
