好开心，终于解决了。从学习android到现在写登录功能已经不是一次两次了，如今再写想着肯定是信手拈来，没有想到的是尽然折磨了我一天的时间才搞定它。唉。。。。。。
先来看几张截图，这次的登录跟以往的不同加了一点东西在上面。下面看截图吧。
下面是我对这次问题的一个截图：
下面这个问题是安卓模拟器访问url的时候出现拒绝的错误。我的解决办法是把url中的127.0.0.1换成了本机的IP地址。就不出现错误了。
下面是我遇到的第二个问题的截图：
出现了乱码，原因是：我编译服务器端的编码不是utf-8。改正为utf-8就可以了。
接下来是我的服务器的配置代码：
<?php
return array(
// 添加数据库配置信息
'DB_TYPE'=>'mysql',// 数据库类型
'DB_HOST'=>'127.0.0.1',// 服务器地址
'DB_NAME'=>'meeting',// 数据库名
'DB_USER'=>'root',// 用户名
'DB_PWD'=>'123456',// 密码
'DB_PORT'=>3306,// 端口
'DB_PREFIX'=>'m_',// 数据库表前缀
'DB_CHARSET'=>'utf8',// 数据库字符集
'DEFAULT_THEME' =>'',
'LAYOUT_ON'=>true,
'LAYOUT_NAME'=>'layout',
);
下面是我的android端的代码：
先看一下目录：
