首先，添加网络权限。
<uses-permission android:name="android.permission.INTERNET"/>
在properties配置文件中，进行配置。
logout=http://ipgw.neu.edu.cn:804/include/auth_action.php login=http://ipgw.neu.edu.cn:804/srun_portal_pc.php?ac_id=1& logoutData=username=20124849&password=XXX&action=logout&ajax=1 loginData=username=20124849&password=XXX&action=login&ac_id=1
布局文件，neu.xml配置文件：
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/btn_login" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="一键登录"/> <TextView android:id="@+id/net_info" android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="20sp"/> </LinearLayout>
properties工具类：
package com.tarena.viewer.util; import java.io.IOException; import java.io.InputStream; import java.util.Properties; public class PropertiesUtil { public static Properties getProperties(){ Properties prop = new Properties(); InputStream is = PropertiesUtil.class.getClassLoader().getResourceAsStream("user.properties"); try { prop.load(is); return prop; } catch (IOException e) { e.printStackTrace(); } return null; } }
最后是全部源码，经过测试，可以一键连接，想要改用户名和密码，就在properties配置文件中进行更改。
