Effective Layout Design with Android ConstraintLayout: A Tutorial

In today’s era where the development of Android apps is becoming increasingly complex,
it’s crucial to create efficient layouts that are both flexible and powerful. This is where
Android ConstraintLayout comes into play. Since its introduction at the Google I/O
Conference 2016, it has proven to be an extremely useful tool for developers to design
complex layouts. In this tutorial, we’ll take a closer look at Android ConstraintLayout and
how to use it.

What is Android ConstraintLayout?

Android ConstraintLayout is a powerful way to create layouts by defining constraints for
each included view element, positioning it relative to other views. Essentially, it simplifies
layout hierarchies and improves application performance by avoiding nested views.

Using Android ConstraintLayout

Before you can start using ConstraintLayout, make sure you’re using the latest version of
Android Studio, preferably version 2.2 or higher. Download the required SDK tools for
ConstraintLayout from the SDK Manager and add the corresponding dependency to your
build.gradle file.

A simple layout can be created as follows:


            <!-- Here you can place your views and add constraints -->


Creating Constraints

A ConstraintLayout works by setting constraints between views. This can be done by
dragging and dropping views in the layout editor of Android Studio. Various anchor points
are available for each view element, which can be used to set constraints.


Automatic Constraint Addition

In addition to manually setting constraints, Android Studio provides tools like Auto-Connect
and Inference, which can automatically add constraints based on various factors such as the
position and size of views.

Deleting Constraints

To remove constraints, you can simply use the corresponding symbols in the layout editor to
delete individual constraints or all constraints of a view.


Android ConstraintLayout is a powerful tool for creating flexible and efficient layouts for
your Android apps. By cleverly using constraints, developers can create complex user
interfaces that are both user-friendly and performant.
