先给大家展示下效果图，如果大家大家感觉不错，请参考实现思路及代码
1 ViewPager类提供了多界面切换的新效果。
新效果有如下特征：
[1] 当前显示一组界面中的其中一个界面。
[2] 当用户通过左右滑动界面时，当前的屏幕显示当前界面和下一个界面的一部分。
[3]滑动结束后，界面自动跳转到当前选择的界面中
2 介绍里面几个比较重要的方法与接口
1,OnPageChangeListener ViewPager页面进行切换监听接口 其中我们经常要实现public void onPageSelected(int arg0)，public void onPageScrolled(int arg0, float arg1, int arg
2),public void onPageScrollStateChanged(int arg0)着三个方面，其中第一个方法是更多的用到;
2,setCurrentItem(int item),来设置跳转到当前的页面;
3,要显示ViewPager,当然还少不了PagerAdapter类，进行适配;其中我们经常也要实现以下方法才可以:public void destroyItem(View arg0, int arg1, Object arg2),public int getCount(),public Object instantiateItem(View arg0, int arg1),public boolean isViewFromObject(View arg0, Object arg1),具体的使用方法等会看例子就ok了
