In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "For instance, you can think of www.google.com as a website's domain name." A block of code is set as follows:
<TextView
android:text="Hello World!"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/TextView"
tools:text="helloWorld"
android:textAppearance="@style/TextAppearance.AppCompat.Headline" />
