Overview of this book

Smartphones and tablets have really changed the technological landscape over the last 3-4 years. Much like the web did in the last decade, these powerful tools have changed the way people communicate and access information. Such a wide market creates opportunities for developers who have the skills to develop mobile applications. "Creating Mobile Apps with Appcelerator Titanium" is a practical, step-by-step guide to building iPhone, iPad, and Android applications using JavaScript. This book will give you a solid grounding of the dos and don'ts of mobile development and also covers a lot of the functionalities offered by the Titanium platform. This book begins with a look at what the Titanium platform has to offer. By taking you through clear tutorials on developing each application step-by-step, it helps you to apply your newly acquired knowledge afterwards. The difficulty level gradually increases along the course of the book. Each application from this book covers different aspects of mobile development. Every chapter starts by defining the application's features as well as the user interface structure. Every single code section is then explained and put into context allowing you to gain a clear understanding of their purpose and functionality. The book takes a “small milestone” approach, allowing you to actually run the application and see the progression. Every step is accompanied by many screenshots so you can see the expected result on screen. You will learn everything you need to know to develop your very own mobile applications. The book takes a laid-back approach to Titanium development and provides information in a way designed to never overwhelm the reader with information and also uses clear diagrams, screenshots, and tips throughout.

The main window

As usual, we want to look before we leap. This means that we have to clearly define our application's user interface before we write a single line of code. Our main window will comprise a container View at the top to hold a label and a button used to refresh the list. The rest of the window will be occupied by a ListView component that will act pretty similar to a TableView component. Each row from the list will comprise an ImageView component for the photo itself and two labels used to display the photo's related information.

Let's dig in the right way

With our UI mockup in hand, we can move on to the implementation. We will create a new file named ApplicationWindow.js in our Resources directory. This new file will contain all the code related to our main window.

We will wrap all our code into a single function called ApplicationWindow:

function ApplicationWindow() {

We will then create our window object and store its reference into a variable named self for later use:

var self...
