Android Application Development Cookbook - Second Edition

Overview of this book

The Android OS has the largest installation base of any operating system in the world; there has never been a better time to learn Android development to write your own applications, or to make your own contributions to the open source community! This “cookbook” will make it easy for you to jump to a topic of interest and get what you need to implement the feature in your own application. If you are new to Android and learn best by “doing,” then this book will provide many topics of interest. Starting with the basics of Android development, we move on to more advanced concepts, and we’ll guide you through common tasks developers struggle to solve. The first few chapters cover the basics including Activities, Layouts, Widgets, and the Menu. From there, we cover fragments and data storage (including SQLite), device sensors, the camera, and GPS. Then we move on more advanced topics such as graphics and animation (including OpenGL), multi-threading with AsyncTask, and Internet functionality with Volley. We’ll also demonstrate Google Maps and Google Cloud Messaging (also known as Push Notifications) using the Google API Library. Finally, we’ll take a look at several online services designed especially for Android development. Take your application big-time with full Internet web services without having to become a server admin by leveraging the power of Backend as a Service (BaaS) providers.

Applying a style to a View


A style is a collection of property settings to define the look of a View. As you have already seen while defining layouts, a view offers many settings to determine how it looks, as well as functions. We have already set a view height, width, background color, and padding, plus there are many more settings such as text color, font, text size, margin, and so on. Creating a style is as simple as pulling these settings from the layout and putting them in a style resource.

In this recipe, we will go through the steps of creating a style and hooking it up to a view.

Similar to Cascading Style Sheets, Android Styles allow you to specify your design settings separate from the UI code.

Getting ready

Create a new Android Studio project and call it Styles. Use the default wizard options to create a Phone & Tablet project and select Empty Activity when prompted for the Activity. By default, the wizard also creates a styles.xml file, which we will use for this recipe.
