Details
A View is one of a set of controls designed to work together to build a typical mobile application framework.
A View, along with a Dialog is used to present the application functionality
The other controls are -
Application title bar which is used as the header of the application
Application Draw which is used to present the application menu
View Container used to manage and organize the views in an application
Application Dialog used as an editor
Navigation Button used as a menu item on the Application Draw
Example
This is a simpified example showing how the various parts interact.
In a real world application, the Views would be reusable parts.
