This looks broken because you're assuming that the bottom bar will always be
exactly 56dp high.  Have you tried looking at your layout in German, or some
other language that has really long strings?  Temporarily plug in long ones and
see how your layout deals with it.

That said, why not use a LinearLayout (e.g.)?

I couldn't find a way to use a LinearLayout that would center the content
correctly while also scrolling on small displays and aligning the button bar to
the bottom of the view. I borrowed heavily from fre_choose_account.xml which
uses the same hard-coded 56dp button bar height.

Plugging in longer strings for "No Thanks" and "Enable" (padded out to 32 chars)
causes the button label to wrap but otherwise renders fine. I linked some
screenshots from bug 529962.

For future reference, the original CL that changed fre_choose_account.xml to
have the 57dp wonkiness:

Given that there's precedence, and given that it works with really long strings
(thanks for checking), this part is fine.  I checked existing translations for
"No thanks" and they don't hit anywhere near 32 chars.
