东北大学校园网一键登录安卓实现

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。
