基于Android移动终端的微型餐饮管理系统的设计与实现2-侧滑菜单

上周发了《 基于Android移动终端的微型餐饮管理系统的设计与实现》第一章，虽然是个简介，但是居然上了首页推荐，还有朋友评论了。写了这么久CSDN，还是第一次有人评论我的文章，真是受宠若惊，长期以来，我一直都以为，我玩的是CSDN单机版。当然，这也说明，我过去写的东西都太烂了，不过这也算是我真实水平的反应吧，希望随着自身水平的提高，能写出更好的博文来，即使写不出，也算是自己成长的记录吧。

今天我先来写一下侧滑菜单，如图：

侧滑菜单的实现方法有很多，网上也有完整的开源框架，现在如果用Android Studio开发的话，一开始选模板的时候就可以选择一个带侧滑菜单的模板。

具体实现方法可以看这篇文章：

我就把我写的代码贴出来给大家好了

然后是java代码，因为侧滑菜单的主要代码基本都写在MainActivity里，我就都贴出来了，启动应用的时候就先启动这个activity，这个小应用主要也是这个activity了，各个页面基本都是以fragment的形式依附在这个activity里的，所以一些设置私有云的代码还有读写上次退出时所在状态的代码也在这里
