Showing multiple screens or pages of content is easy with the help of ViewPager and a PagerAdapter. Combining that with tabs make for an effective top level navigation strategy (https://www.google.com/design/spec/pa...) for your app or for moving between content at the same level of hierarchy within your app.
TabLayout ensures that your tabs matches the material design guidelines (https://www.google.com/design/spec/co...) and integrate easily with ViewPager to make jumping between pages and getting an overview of all pages much easier.
