Overview of this book

Kotlin is a programming language intended to be a better Java, and it's designed to be usable and readable across large teams with different levels of knowledge. As a language, it helps developers build amazing Android applications in an easy and effective way. This book begins by giving you a strong grasp of Kotlin's features in the context of Android development and its APIs. Moving on, you'll take steps towards building stunning applications for Android. The book will show you how to set up the environment, and the difficulty level will grow steadily with the applications covered in the upcoming chapters. Later on, the book will introduce you to the Android Studio IDE, which plays an integral role in Android development. We'll use Kotlin's basic programming concepts such as functions, lambdas, properties, object-oriented code, safety aspects, type parameterization, testing, and concurrency, which will guide you through writing Kotlin code in production. We'll also show you how to integrate Kotlin into any existing Android project.

Preface

Dialog fragments


If you need to display any of your fragments floating above the rest of application's UI, then DialogFragment is perfect for you. All you need to do is define the fragment very similarly to what we did so far. Define the class that is extending DialogFragment. Override the onCreateView() method so you can define the layout. You can override onCreate() as well. The last thing you have to do is to display it as follows:

    val dialog = MyDialogFragment() 
    dialog.show(supportFragmentManager, "dialog") 

In this example, we passed the instance and the name for the transaction to the fragment manager.
