title: Add button to bottom of linear layout programmatically
body: <p>I have a bunch of buttons displayed using the default gravity. The last button I add to the LinearLayout view is what I'd like to appear at the bottom of the view. How do I add it programmtically to appear at the bottom of the screen? I've tried setting the gravity, but everything falls to the bottom. I just want the one button to fall to the bottom of the screen. Ideally, I won't have to make another view.</p>
