title: Difference between PagerTabStrip and TabLayout
body: <p>I am working on an app where I want to add tabs so that can be added using <code>PagerTabStrip</code> and <code>TabLayout</code> with ViewPager.</p>
  
  <p>It looks same to me with no difference but I guess there is some difference between them so they are two classes for this. So what is the main difference between them?</p>
