Android 基于TabLayout实现的TAB页导航切换效果 仿今日头条底部的TAB选项卡效果，TabLayout与ViewPager结合使用可以达到点击tab更新ViewPager、滑动ViewPager更新Tab的效果。这种效果现在在PC端、移动设备端已经很常见了，这一个代码开源，制作方法简单，效果简洁，手轻触对应的TAb，显示的内容对应切换。 　　你可以学习下在Android开发中，tablelayout 与viewpager如何关联，如何创建每个tag标签对应的Fragment，本源码中是创建5个标题并加入布局中，实际应用中，你可以根据需要添加或减少对应的TAb布局数量。 　　编译时请在网上下载mockable-android-23.jar到uildgenerated目录下。

这个例子套用的是不错的
