TUTORIAL 34
More Home Cooking
In this tutorial, we will add a few more features to our existing app widget,
such as a button to choose another random restaurant. Also, if the user taps
on the name of the restaurant, we will open up the detail form activity for
that restaurant.
Step-By-Step Instructions........................................................................
First, you need to have completed the previous tutorial. If you are
beginning the tutorials here, or if you wish to not use your existing work,
you can download a ZIP file with all of the tutorial results, and you can copy
the 33-AppWidget edition of LunchList to use as a starting point.
Step #1: Implement a Shaker.............................................................
Next, you will need an image to go on an ImageButton that will serve to
change the restaurant shown by the app widget to another random
restaurant.
If you examine the 34-AdvAppWidget project in the book's source code
repository, you will see that there is a ff.png file there, culled from the
Android open source project, that you could use. Or, substitute your own
graphic as you see fit – just name it ff.png to match how it is used later in
this tutorial.
