What I have so far for MainActivity.java.

I've commented out some code for the moment. I'm trying to get the layout running. Some changes to other files indicated that we may be starting over with the layout. Left unsure of what to do, I've attempted to modify the old layout making it usable again. I'm still hard at work, but I thought I'd post what I had so far. I expect to make more significant changes to this file later tonight.
