21 PagerTabStrip-PagerTitleStrip-viewPager

• PagerTabStrip:可以点击跳转到对应viewPager界面
• PagerTitleStrip：不可点击

• 在eclipse开发时如果目标版本为API23那么会有不显示的问题

  • 解决：更换v4包

  • 解决: 在Activiry的oncreate方法中添加如下代码

    ((ViewPager.LayoutParams) tabStrip.getLayoutParams()).isDecor = true;

    （我试了下我的不行但网上有说可以）

  • studio开发貌似可以

• 文件结构:
