Overview of this book

Xamarin.Forms is a lightweight cross-platform development toolkit for building apps with a rich user interface. Improved and updated to cover the latest features of Xamarin.Forms, this second edition covers CollectionView and Shell, along with interesting concepts such as augmented reality (AR) and machine learning. Starting with an introduction to Xamarin and how it works, this book shares tips for choosing the type of development environment you should strive for when planning cross-platform mobile apps. You’ll build your first Xamarin.Forms app and learn how to use Shell to implement the app architecture. The book gradually increases the level of complexity of the projects, guiding you through creating apps ranging from a location tracker and weather map to an AR game and face recognition. As you advance, the book will take you through modern mobile development frameworks such as SQLite, .NET Core Mono, ARKit, and ARCore. You’ll be able to customize your apps for both Android and iOS platforms to achieve native-like performance and speed. The book is filled with engaging examples, so you can grasp essential concepts by writing code instead of reading through endless theory. By the end of this book, you’ll be ready to develop your own native apps with Xamarin.Forms and its associated technologies, such as .NET Core, Visual Studio 2019, and C#.

Building a Photo Gallery App Using CollectionView and CarouselView

In this chapter, we will build an app that shows photos from the camera roll (photo gallery) of a user's device. The user will also be able to select photos as favorites. We will then look at the different ways to display photos—in carousels and in a multi-column grid control. If we learn how to use these controls, we can then use them in a lot of other cases when we build real-world apps.

The following topics will be covered in this chapter:

  • How to import photos from the iOS photo gallery
  • How to import photos from the Android photo gallery
  • How to use CarouselView in Xamarin.Forms
  • How to use CollectionView in Xamarin.Forms
