Android中的注册信息页面涉及到链接网络

摘要: 本部分是Android客户端的注册信息界面，用户把需要注册的信息填写之后提交给服务器，服务器在返回是否注册成功，本模块涉及到对网络环境的判断（当前网络是否可用），还有线程之间的通信问题，以表单形式提交用户数据，配置ip地址（用到了配置文件sharedpreferences）,

一个Android应用总是离不开xml布局文件和逻辑代码部分

1.把布局文件命名为regis.xml（当然读者也可以定义为别的名字）

3.本模块用到了几个权限，还要在AndroidManifest.xml中注册新的Activity否侧会出错的，权限如下，请读者自行加到AndroidManifest.xml中

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

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

说明：此部分代码可能复制过去无法运行，还请读者调试一下，本代码不是最优的代码，也可能有错，欢迎读者指出其中的错误，感激不尽！
