You don’t need a third-party library for this

In this article, we will learn how to architect and implement a view pager — a UI element a lot of apps use. This is what we will have by the end of the tutorial:

We will also make it reusable and composable so that you can use it with or without a tabbed view on top.

The source code of the project is available at the bottom of the article.

Let’s Get Started

If we deconstruct the ViewPager component into smaller bits, we will see that it consists of two parts: tabbed view on top, and paged view below. Ideally, we want to either use both of those elements at the same time or involve only the paged view component. For this reason, we will have three main classes:

• ViewPager: combines TabbedView and PagedView and makes them work together
• TabbedView: top element allowing only one tab to be selected at a time.
• PagedView: bottom element that has “pages,” which we can scroll.
