Creating Dynamic UI with Android Fragments



To create a dynamic and multi-pane user interface on Android, you need to encapsulate UI components and activity behaviors into modules that you can swap into and out of your activities. You can create these modules with the fragment class, which behaves somewhat like a nested activity that can define its own layout and manage its own lifecycle. When a fragment specifies its own layout, it can be configured in different combinations with other fragments inside an activity to modify your layout configuration for different screen sizes (a small screen might show one fragment at a time, but a large screen can show two or more).

Creating Dynamic UI with Android Fragments shows you how to create modern Android applications that meet the high expectations of today’s users. You will learn how to incorporate rich navigation features like swipe-based screen browsing and how to create adaptive UIs that ensure your application looks fantastic whether run on a low cost smartphone or the latest tablet.

This book looks at the impact fragments have on Android UI design and their role in both simplifying many common UI challenges and providing new ways to incorporate rich UI behaviors.

You will learn how to use fragments to create UIs that automatically adapt to device differences. We look closely at the roll of fragment transactions and how to work with the Android back stack. Leveraging this understanding, we then explore several specialized fragment-related classes like ListFragment and DialogFragment as well as rich navigation features like swipe-based screen browsing.

What you will learn from this book:

  • Understand the role and capabilities of fragments
  • Explore the fragment-oriented features of Android Studio
  • Create an app UI that works effectively on smartphones and tablets
  • Use fragments to create engaging navigation capabilities like swipe-based screen browsing
  • Work with special purpose fragment classes like ListFragment and DialogFragment
  • Dynamically manage fragments using the FragmentTransaction class
  • Learn appropriate application design for communicating between fragments
  • Efficiently handle fragment creation and lifecycle
  • Simplify cross-thread UI handling with fragments
  • Form multi-screen UIs that run within a single activity
