-This assignment is about creating the Rolodex application that contains the contact information. Each contact information includes:

First name

Last name

Middle name (optional)

Phone number

-The Rolodex application will use SharedPreferences for data persistent operations:

-Retrieve Rolodex records

-Add a new Rolodex record

-Update the existing Rolodex record

-Delete the selected Rolodex record

-The Rolodex application uses Fragment and DialogFragment. In addition, the Rolodex records are displayed in the ListView view. The ListView view is set to be single-selection mode.

-Each row in the ListView view is another layout. The layout for each row contains two TextView views.

-The top TextView view contains the name of the contact, starting the last name, then the comma, and followed by the first name and middle name.

-The bottom TextView view contains the phone number.
