How the activity lifecycle works at a high level.How to add resource XML files and Kotlin files to an Android Studio project.Prerequisitesīefore completing this codelab, you should know By the end of this codelab, you'll come away with the foundational skills for implementing fragments in your next app. You'll also learn how to use the Jetpack Navigation component and work with a new resource file called the Navigation Graph to navigate between fragments in the same host activity.
In this codelab, you'll learn the basics of fragments, and convert the Words app to use them. Both fragments exist simultaneously in the same activity.Īs you can see, fragments are an integral part of building high quality apps. In the example below, both the navigation UI on the left and the content on the right can each be contained in a separate fragment. You can even show multiple fragments at once on a single screen, such as a master-detail layout for tablet devices. All of this happens without launching another activity. Instead, switching tabs simply swaps out the previous fragment with another fragment. In the above screenshot, tapping on a tab doesn't trigger an intent to display the next screen. In fact, many common UI patterns, such as tabs, exist within a single activity, using something called fragments.Ī fragment is a reusable piece of UI fragments can be reused and embedded in one or more activities. Many Android apps don't need a separate activity for every screen. While this is a useful navigation pattern to know, it's only part of the story of making dynamic user interfaces for your apps. Import 7.app.In the Activities and Intents codelab, you added intents in the Words app, to navigate between two activities. Step 3 − Add the following code to src /MainActivity.java package In the above code, we have taken button views and linear layout to show different fragments. Step 2 − Add the following code to res/layout/activity_main.xml. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
