转载:http://www.cnblogs.com/ghj1976/archive/2011/04/26/2028904.html

效果图:


使用的ksoap包在附件
KSOAP2 地址：http://code.google.com/p/ksoap2-android/
1. 导入ksoap2的jar包

2. 在AndroidManifest.xml中加入访问网络权限

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

3. 看完整代码:

		okButton.setOnClickListener(new Button.OnClickListener() {

    }
