筆者之前已經做過了一個使用viewpgaer輪播效果的博客，但是viewpager本身也是深受androider的喜愛，如今基本每個app都會用到相關的功能，本篇文章也是講一下用viewpager做主界面的用法。（筆者對viewpager的學習也是比較曲折，網上各種找不到符合自己功能的代碼） 筆者之后又學習了viewpager+fragment的使用，地址為：[http://blog.csdn.net/double2hao/article/details/50450377](http://blog.csdn.net/double2hao/article/details/50450377) 主要功能：**（源碼在文章最后）** 1、滑動的同時改變標題欄 2、點擊標題欄的同時滑動 效果：  ? ? ? 主要文件：  ? ? ??
