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 photo viewer window


The photo search part of our application is now behind us and we will now move on to our second window that will be used to view the selected photo when the user clicks on a specific row.

The user interface for this window is quite straightforward. We will have a header View sitting at the top of the screen that will contain both Label and Buttons for the photo's title.

The rest of the window will be entirely occupied by an Image View component that will display the photo:

On with the code

For the sake of clarity, we will keep all the code related with this window in its own file. We will create a new file named PhotoViewerWindow.js in our Resources directory.

In this newly created file, we will create a function named PhotoViewerWindow that will encapsulate everything related to our window. This function will take a single argument (the selected photo) and since the parameter itemId is a string, we will parse it into a JavaScript object:

function PhotoViewerWindow(itemId...
