![]() ![]() Android Studio templates also include this dependency for new projects. The starter app already includes the dependency in adle. The constraint-layout dependency is provided as a separate support library that works on all Android versions back to Android 2.3 (Gingerbread). To use ConstraintLayout, the appropriate support library must be included in the adle (Module: app) file in your project. The constraint-layout screen should appear: Click the Run button, and either choose an emulator or connect your Android device, which must be capable of running Android Lollipop (the minimum SDK supported is 22).Open the constraint-layout-start project in Android Studio.Open the constraint-layout-master folder to see the constraint-layout-start folder.If you downloaded the constraint-layout-master zip file, unzip the file.Follow these instructions to open the sample app in Android Studio. How do set up a device for development?įirst, let's see what the finished sample app looks like.constraint-layout-start - Project that contains the layouts that you'll build upon in this codelab.The constraint-layout repository contains one app project: or clone the GitHub repository from the command line by using the following command: $ git clone To download the sample app, you can either: The sample app: constraint-layout-start.Android Studio Bumblebee (the codelab may work with earlier versions, but some things might be missing or look different).Use chains to position multiple elements.Use barriers to align elements that dynamically vary in size.Learn to infer constraints for a layout automatically.How to adjust an element's layout dimensions and margins.How to add constraints in order to position and align elements to other elements.How to place and resize elements in the layout.Learn to automatically constrain UI elements to the layout.Some Android app development experience.By the end of this codelab, you'll have enough experience with the Layout Editor in Android Studio to be able to build a complex layout such as the one shown below. You will be working primarily with the Layout Editor for this codelab and will not directly be editing the XML or Java code. A constraint represents a connection or alignment to another view, the parent layout, or an invisible guideline. The Layout Editor uses ConstraintLayout to determine the position of a UI element. ![]() In this codelab, you'll learn how to use the Android Studio Layout Editor with ConstraintLayout-a new, flexible, and efficient layout available in the Android Support repository. ![]()
