Android UI Development with Jetpack Compose

By: Thomas Künneth

Overview of this book

Jetpack Compose is Android’s new framework for building fast, beautiful, and reliable native user interfaces. It simplifies and significantly accelerates UI development on Android using the declarative approach. This book will help developers to get hands-on with Jetpack Compose and adopt a modern way of building Android applications. The book is not an introduction to Android development, but it will build on your knowledge of how Android apps are developed. Complete with hands-on examples, this easy-to-follow guide will get you up to speed with the fundamentals of Jetpack Compose such as state hoisting, unidirectional data flow, and composition over inheritance and help you build your own Android apps using Compose. You'll also cover concepts such as testing, animation, and interoperability with the existing Android UI toolkit. By the end of the book, you'll be able to write your own Android apps using Jetpack Compose.

Chapter 6: Putting Pieces Together

The previous chapters explored various aspects of Jetpack Compose. For example, Chapter 2, Understanding the Declarative Paradigm, compared the traditional View system to composable functions and explained the benefits of the declarative approach. Chapter 4,Laying Out UI Elements, gave you a solid understanding of some built-in layout composables such as Box(), Row(), and Column(). In Chapter 5, Managing the State of Your Composable Functions, we looked at state and learned about the important role it plays in a Compose app.

Now, it's time to see how these key elements work together in a real-world app. In this chapter, you will learn how Compose apps can be themed. We will also look at Scaffold(), an integrational UI element that picks up quite a few concepts that were originally related to activities, such as toolbars and menus, and we will learn how to add screen-based navigation.

In this chapter, we will cover the following topics:
