CoffeeMate 3.0 - A First Look

When we're finsihed this lab, we'll be able to display the users Favourite coffees and apply a filter to the list of coffees so the user can search on a coffee name or type, or both. If you've run the starter code (and it's recommended you do) you'll see that the 'Search' & 'Favourites' buttons are working, but not functioning properly - we're not seeing any refined list of coffees.

Furthermore, there's nothing to select from the Spinner (second screenshot above) so this lab is all about refactoring existing classes to get these features working.

It's also worth taking a look at our Home.java below just to confirm you understand how we implemented the button functionality (see below).

The following steps will take you through completing CoffeeMate 3.0.
