TabLayout is a horizontal layout in which different tabs will be available to swipe between them using viewpager2.
In the below project, we have used two tabs login and signup tabs where we will swipe between them. TabLayout is often used with viewpager2.

In the below project, we have used viewpager2 to swipe between the login and signup pages.
