Step #5: Build and Attach the Adapter...............................................

The ListView will remain empty, of course, until we do something to

populate it. What we want is for the list to show our running lineup of

restaurant objects.

Since we have our ArrayList, we can easily wrap it in an

ArrayAdapter. This also means, though, that when we add a

restaurant, we need to add it to the ArrayAdapter via add() – the adapter

will, in turn, put it in the ArrayList. Otherwise, if we add it straight to the

ArrayList, the adapter will not know about the added restaurant and

therefore will not display it.
