You have two broad-brush choices for how to build the GUI portion of
this app:
1. Use the 2D graphics API and touch events. If you wish to go that
route, I heartily recommend Ed Burnette's _Hello, Android_, as he works
through creating a Sudoku game using this technique.
2. Use widgets, as you are trying to do. It is possible you will achieve
your goal ("a very graphical game and not just a grid of buttons with
text"), but it might get rather involved to get a specific look. For
example, GridView does not allow you to change the thickness of the
divider lines, which you might feel is important. That would suggest you
might not want to use GridView but rather something else. Off the cuff,
I would try a TableView and draw my own grid lines, with nine ImageViews
for the game-play cells (holding X, O, or being transparent
placeholders). But, then again, I haven't given that a lot of thought.
Generally speaking, you will get better results on this list if you ask
focused, tactical questions. I have some advice I posted on getting
assistance with Android up on AndroidGuys:
