基於Android移動終端的微型餐飲管理系統的設計與實現2-側滑菜單

今天我先來寫一下側滑菜單，如圖：

側滑菜單的實現方法有很多，網上也有完整的開源框架，現在如果用Android Studio開發的話，一開始選模板的時候就可以選擇一個帶側滑菜單的模板。

我就把我寫的代碼貼出來給大家好了

xml文件：

然後是java代碼，因為側滑菜單的主要代碼基本都寫在MainActivity裡，我就都貼出來了，啟動應用的時候就先啟動這個activity，這個小應用主要也是這個activity了，各個頁面基本都是以fragment的形式依附在這個activity裡的，所以一些設置私有雲的代碼還有讀寫上次退出時所在狀態的代碼也在這裡

順便把activuty_main.xml裡的代碼貼一下，裡面雖然沒有什麼東西，但是這個界面很重要，因為其它界面都是依附在它上面的
