安卓开发中用户的注册和登陆实现 Android开发中实现用户注册和登陆的代码实例分享
人气:0想了解Android开发中实现用户注册和登陆的代码实例讲解的相关内容吗，在本文为您仔细讲解安卓开发中用户的注册和登陆实现的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：Android,用户,注册,登陆，下面大家一起来学习吧。
在android的应用中越来越多的包含了网络互动功能，这就带来了注册，登陆账号功能。本文完整的介绍对话框的方式实现用户登陆功能。
登陆效果： 应用程序判断当前用户还未登陆，弹出登陆对话框，用户输入账号和密码信息后，传到服务器验证，验证成功后，现实Toast 成功信息，并转到其他界面。
注册效果：用户如没有账号，则点击登陆对话框的 "没有账号，快速注册账号"， 弹出注册界面,用户输入注册信息，点击注册按钮，注册成功后，弹出toast信息"注册成功"，完成注册后，转到其他功能界面。
整个功能大体上分两块：登陆对话框：输入登陆信息，实现登陆功能，转到注册界面。注册对话框：输入注册信息，实现注册功能。
