This is the way I did it, but anything that is functional is acceptable.
++ Main UI ++ Display view (Activity or Dialog)
Button (to create an entry) TextView (for title)
ListView (of entries) TextView (for description)
ImageView (for photo)
++ ListView item UI TextView (for date and time)
ImageView (for photo) TextView (for location)
TextView (for title) Button (for save)
TextView (for date and time) Button (for delete)
++ Database
id - int
title - String
description - String
photoUri - String
time - String (trick to allow look up from list click)
latitude - double
longitude - double
