1、寫在前面的話
上一篇已經介紹了fragment的使用封裝，讀者可以點擊鏈接查看fragment的使用封裝（上）:http://blog.csdn.net/q649381130/article/details/51340544。
本文主要採用其他方式，實現對fragment的添加切換操作。效果圖就不上了，跟上篇一樣。
2、傳統方式
在Activity中我們添加一下常量，表示對於fragment的tag標示，用枚舉一樣的效果。

提供一個工廠方法，根據傳入的tag進行fragment對象的創建

提供一個切換顯示fragment的方法，傳入tag值，根據tag值顯示對應的頁面。首先我們先去棧中查找看是否存在對應的fragment，如果已經存在就直接顯示隱藏，否則使用工廠方法創建實例在add進來，add的時候將tag與新建的fragment對象對應起來。

完整代碼業務邏輯還是很簡單的，這裏我們重寫了onBackpress()方法，控制當用戶點擊返回鍵時，如果當前頁面是列表頁則退出Activity，否則切換顯示列表頁面。
當然還要重寫onSaveInstanceState()，防止重複顯示的bug。具體解釋看我的上一篇博客。

3、文藝式
文藝式的精髓就是使用指定view的id作爲tag，這樣實現對代碼的最大化精簡，減少配置參數。
先看HomeSettingFragment中的代碼，在自定義點擊事件中，我們直接調用MainActivity的replace方式，傳入被點擊的view的id即可。

然後在MainActivity中，我們根據傳入的id進行fragment的創建，添加，查找。大量減少一些常量，可以降低在出現差錯的風險。
