Learning Material Design
by Kyle MewMaster Material Design and create beautiful, animated interfaces for mobile and web applications About This Book * Master the highly acclaimed Material Design paradigm and give your apps and pages the look that everyone is talking about * Get a mix of key theoretical concepts combined with enough practical examples to put each theory into practice so you can create elegant material interfaces with Android Studio and Polymer * Written by Kyle Mew, successful author with over a decade of mobile and web development experience, this book has both the touch of a developer as well as an experienced writer Who This Book Is For This book is ideal for web developers and designers who are interested in implementing Material Design in their mobile and web apps. No prior knowledge or experience of Material Design is required, but some familiarity with procedural languages such as Java and markup languages such as HTML will provide an advantage. What You Will Learn * Implement Material Design on both mobile and web platforms that work on older handsets and browsers * Design stylish layouts with the Material Theme * Create and manage cards, lists, and grids * Design and implement sliding drawers for seamless navigation * Coordinate components to work together * Animate widgets and create transitions and animation program flow * Use Polymer to bring Material Design to your web pages In Detail Google's Material Design language has taken the web development and design worlds by storm. Now available on many more platforms than Android, Material Design uses color, light, and movements to not only generate beautiful interfaces, but to provide intuitive navigation for the user. Learning Material Design will teach you the fundamental theories of Material Design using code samples to put these theories into practice. Focusing primarily on Android Studio, you'll create mobile interfaces using the most widely used and powerful material components, such as sliding drawers and floating action buttons. Each section will introduce the relevant Java classes and APIs required to implement these components. With the rules regarding structure, layout, iconography, and typography covered, we then move into animation and transition, possibly Material Design's most powerful concept, allowing complex hierarchies to be displayed simply and stylishly. With all the basic technologies and concepts mastered, the book concludes by showing you how these skills can be applied to other platforms, in particular web apps, using the powerful Polymer library. Style and approach Learning Material Design combines the theories behind material design with practical examples of how these can be implemented and further reinforcing the guidelines covering style, layout and structure.

It continues by introducing the new Java 8 syntax features, such as lambdas and function references, and some functional programming basics. From this point on, the book focuses on RxJava in depth. It goes through creating Observables, transforming, filtering, and combining them, and concurrency and testing to finish with extending the library itself. <P><P>This book is a definite tutorial in RxJava filled with a lot of well-described examples. It explains reactive programming concepts in plain and readable language, without scientific formulas and terms.
