Change code formatting and fixed bug with the sample app

[davidjrichardson]

I've changed the code style to be a little more in-line with the Google AOSP code style guidelines. More specifcally, I've changed it so all lines are less than 100 characters as outlined here: https://source.android.com/source/code-style.html#limit-line-length

I have also fixed an issue with the sample app where the centre gravity field had no hint defined within the XML.

:) hmm.. this is a tough one. Some thoughts:

• Thanks for the link to the AOSP guide. I remember reading about it sometime back.
• Problem is, I don't completely follow/like the AOSP guide.
• I find code readability to be supremely important. Some of the AOSP rules come in the way of reading code (i suppose this is a personal preference) for e.g. not adding a space before parenthesis.
• Above all else is consistency. I believe the existing code is consistent to a specific set of rules. Applying your changes might come in the way of that consistency.

What are these rules you ask? I've been working/tweaking on them for sometime now, and have them up on another repo: https://github.com/kaushikgopal/jetbrains_env

Those rules are basically for Android Studio. I hit a command and boom, the code is formatted to the rules specified. That's how i tackle consistency.

Thoughts?

Those are fair points in regards to formatting and I agree that consistency is key when it comes to code readability. The main issue right now (in my opinion) is that the existing code has potentially quite long line lengths or the large indentations used for method parameters (although this could just be another personal preference).

As an aside, the existing code doesn't seem to follow your provided formatting rules. :)
