Conventions

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: 

"We can use the getWidth() and getHeight() methods to get the width and height, respectively, of the view."

A block of code is set as follows:

<com.packt.rrafols.customview.OwnTextView 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:text="Hello World!" /> 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

float maxLabelWidth = 0.f; 
if (regenerate) { 
    for (int i = 0; i<= 10; i++) { 
        float step; 
 if (!invertVerticalAxis) {
   step = ((float) i / 10.f);
  } else {
   step = ((float) (10 - i)) / 10.f;
}

New terms and important words are shown in bold, for example, they appear in the text like this: "The layouts are usually known as ViewGroup."
