1. Purpose

The purpose of this exercise was to create a useful golf application. This was to done by gathering available information and presenting it with a functional user interface.

1. Introduction

The applicationinitially launches a ListView within a ListActivity. The onCreate method calls a custom adapter, IconAdapter, to bind the data to the ListView. The IconAdapter stores each icon within an ArrayList, displays them in the ListView and provides services for the data.

The user can interact with the application through the option menu, context menu and dialog boxes. The option menu provides a “Quit” option for the user. The context menu can be used initiate a phone call to each course when the ListView is pressed and held. It launches an ACTION_CALL intent for the selected phone number in that phone array.

A dialog box is created when an onListItemClick event is fired. This will present the user with three options: Tee Time, Web Page and Map. Each of these options launches an ACTION_VIEW intent. The “Tee Time” button opens the browser with the contents of the url array. Here the user has access to the courses reservation service. The “Web Page” button opens the browser to the course website with the contents of the page array. The “Map” button uses the Google API to present a map based upon coordinates in the lat and lon arrays.
