笔者之前已经做过了一个使用viewpgaer轮播效果的博客,但是viewpager本身也是深受androider的喜爱,如今基本每个app都会用到相关的功能,本篇文章也是讲一下用viewpager做主界面的用法。(笔者对viewpager的学习也是比较曲折,网上各种找不到符合自己功能的代码)
笔者之后又学习了viewpager+fragment的使用,地址为:[http://blog.csdn.net/double2hao/article/details/50450377](http://blog.csdn.net/double2hao/article/details/50450377)
主要功能:**(源码在文章最后)**
1、滑动的同时改变标题栏
2、点击标题栏的同时滑动
效果:
