Besides what is mentioned above, you can store the 'Left' and 'Top' properties in a 2-field SQLite table
(as you are dragging the views).. means the L&T fields are updated in real time, and when you are done
with the drag, then the SQLite fields hold the last values of the view's L&T properties.
When you run your app again, don't forget to assign the L&T of the view to the stored values, so it can
show the last position before closing the app. (Activity.Create)
