Android利用ViewPager实现滑动广告板

•android-support-v4.jar,这是谷歌官方给我们提供的一个兼容低版本Android设备的软件包，里面包囊了只有在Android3.0以上可以使用的api。而ViewPager就是其中之一,利用它我们可以做很多事情，从最简单的导航，到页面切换菜单等等。
•ViewPager的功能就是可以使视图滑动，就像Lanucher左右滑动那样。
•本Demo向大家演示ViewPager的使用，并在用户未滑动View时，每隔5s钟自动切换到下一个View(循环切换)，而当用户有Touch到View时取消5s自动切换功能。并有指示器指示当前处于哪一个View。

下面是运行的截图：

这个是非常常见的应用
下面给出实现的代码：
