Who This Book Is For

This book is for developers with a basic understanding of Android programming who would like to improve the appearance and usability of their applications by creating a more interactive user experience and dynamically adaptive UIs; providing better support for tablets and smartphones in a single app; and reducing the complexity of managing app UIs.

What You Will Learn

• Learn the role and capabilities of fragments
• Use Android Studio’s fragment-oriented features
• Create an app UI that works effectively on smartphones and tablets
• Manage the creation and life cycle of fragments
• Dynamically manage fragments using the FragmentTransaction class
• Learn the application design for communicating between fragments
• Leverage fragments when implementing applications that take advantage of the latest features of Material Design

In Detail

Today’s users expect mobile apps to be dynamic and highly interactive, with rich navigation features. These same apps must look fantastic whether running on a medium-resolution smartphone or high-resolution tablet. Fragments provide the toolset we need to meet these user expectations by enabling us to build our applications out of adaptable components that take advantage of the rich capabilities of each individual device and automatically adapt to their differences.

This book looks at the impact fragments have on Android UI design and their role in both simplifying many common UI challenges and in providing best practices for incorporating rich UI behaviors. We look closely at the roll of fragment transactions and how to work with the Android back stack. Leveraging this understanding, we explore several specialized fragment-related classes such as ListFragment and DialogFragment. We then go on to discuss how to implement rich navigation features such as swipe-based screen browsing, and the role of fragments when developing applications that take advantage of the latest aspects of Material Design.

You will learn everything you need to provide dynamic, multi-screen UIs within a single activity, and the rich UI features demanded by today’s mobile users.

Style and approach

A fast-paced learning guide that gives a hands-on, code-intensive approach with a focus on real-world applications.

In Detail

如今，用户希望移动应用程序是动态的、高度互动的，并具有丰富的导航功能。无论是在中等分辨率的智能手机上运行，还是在高分辨率的平板电脑上运行，这些应用程序都必须看起来非常棒。片断提供了满足这些用户期望所需的工具集，使我们能够使用可适应的组件构建应用程序，这些组件利用每个单独设备的丰富功能并自动适应它们的差异。

这本书着眼于碎片对Android用户界面设计的影响，以及它们在简化许多常见的用户界面挑战以及为整合丰富的用户界面行为提供最佳实践方面所扮演的角色。我们仔细研究了大量的碎片事务，以及如何使用Android后台堆栈。利用这一理解，我们探索了几个专门的片段相关类，如ListFragment和DialogFragment。然后，我们继续讨论如何实现丰富的导航功能，如基于滑动的屏幕浏览，以及在开发利用材料设计的最新方面的应用程序时片段的作用。

您将学习在单一活动中提供动态、多屏幕用户界面所需的一切，以及当今移动用户所需的丰富用户界面功能。

Style and approach

这是一个快节奏的学习指南，提供了一种动手的、代码密集的方法，重点放在现实世界的应用程序上。
