Kotlin and Android Development featuring Jetpack

Build a Fragment (Pick Players)

Throughout this book, we’re going to be using <ConstraintLayout> view groups as the main containers for most of our screens. We could handle things a few ways, but <ConstrainLayout> is a great way to get things right where you want them on each screen while still allowing for the flexibilty needed for multiple device types. In fragment_pick_players.xml, we can replace the entire existing <FrameLayout> tag with this new <ConstraintLayout>. The XML will then look like this:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" ...
