Overview of this book

Are you an Android developer with some experience under your belt? Are you wondering how the experts create efficient and good-looking apps? Then your wait will end with this book! We will teach you about different Android development patterns that will enable you to write clean code and make your app stand out from the crowd. The book starts by introducing the Android development environment and exploring the support libraries. You will gradually explore the different design and layout patterns and get to know the best practices of how to use them together. Then you’ll then develop an application that will help you grasp activities, services, and broadcasts and their roles in Android development. Moving on, you will add user-detecting classes and APIs such as gesture detection, touch screen listeners, and sensors to your app. You will also learn to adapt your app to run on tablets and other devices and platforms, including Android Wear, auto, and TV. Finally, you will see how to connect your app to social media and explore deployment patterns as well as the best publishing and monetizing practices.

Using the factory with the RecyclerView


As we saw briefly earlier in the book, RecyclerViews make use of an internal LayoutManager. This in turn communicates with the data set by use of an adapter. These adapters serve exactly the same function as the adapter design pattern we explored earlier in the book. The function may not appear so readily apparent, but it acts as a connection between a dataset and a recycler view's layout manager. The adapter crosses this bridge with its ViewHolder. The workings of the adapter are neatly separated from the client code, and all we need are a few lines to create a new adapter and layout manager.

With this in mind and our data ready, we can quickly put an adapter together by following these simple steps:

  1. Begin by creating this new class in your main package:

    public class DataAdapter extends RecyclerView.Adapter<DataAdapter.ViewHolder> { 
    
  2. It requires the following field and constructor:

    private List<Cheese> cheeses; 
     
    public DataAdapter...
