Enable the Create layout XML? option and disable both the Include fragment factory methods and Include interface callbacks options before clicking on the Finish button to create the new fragment: In the resulting dialog, enter Tab1Fragment into the Fragment Name: field and fragment_tab1 into the Fragment Layout Name: field. Create the first of these fragments by right-clicking on the app -> java -> entry in the Project tool window and selecting the New -> Fragment -> Fragment (Blank) option. The remainder of this chapter will work through the creation of an example project that demonstrates the use of the TabLayout component together with a ViewPager and four fragments.Įach of the tabs on the TabLayout will display a different fragment when selected. Figure 31 1, for example, shows the tab bar for the Android phone app consisting of three tabs displaying images:įigure 31-2, on the other hand, shows a TabLayout configuration consisting of four tabs displaying text in a scrollable configuration: The information displayed on a tab can be text-based, an image or a combination of text and images. The tabs can be fixed or scrollable, whereby the user can swipe left or right to view more tabs than will currently fit on the display. The purpose of the TabLayout is to present the user with a row of tabs which can be selected to display different pages to the user. ![]() You can find the app’s source code on Github.Report this ad An Overview of the TabLayout ComponentĪs previously discussed, TabLayout is one of the components introduced as part of material design and is included in the design support library. You don’t need to implement gesture listeners since the component does that for you. This is a common UI component, and almost all apps that display data in page format use it.Īchieving the slide transition between content screens is relatively easy with the component. We have also seen how we can integrate it with a TabLayout. In this article, we have gone through creating the ViewPager2 component. ![]() TabLayout.addOnTabSelectedListener( object : TabLayout.OnTabSelectedListener reselected", Toast.LENGTH_SHORT).show() Our activity_main layout file will contain only two views. On the next page, give the application a name and keep the default settings.Ĭlick Finish and wait for the project build process to finish. Open Android Studio and start a new project using the empty activity template. In this step, we’re going to create our application. Let’s get started! Step 1 - Creating an Android Project Have a basic understanding of Kotlin programming language.Have a basic knowledge of building Android applications.To follow through with this tutorial, you will need to: This article goes through implementing ViewPager2 and TabLayout in an Android application. This improves user experience by making smooth transitions and minimizing memory usage. ![]() A significant difference from the old library is the use of a RecyclerView adapter. ViewPager2 is a newer version of the ViewPager library. A TabLayout indicates the current page and allows a user to switch through pages. ViewPager2 is often integrated with TabLayout. This feature is common in content display applications and in app setups. ![]() This view allows the developer to display views or fragments to the user in a swipe-able format. The ViewPager library has been around for quite a while. We can use the navigation components or a swipe-able view to create this transition. Slide transition between screens is common in Android applications.
