I can't view the picture you attached but "huge" and "complex" are at least
bad signs. :)  You should never -need- to have a huge and complex view
hierarchy, and this is one of the first things you will fix because it
impacts performance all over the place.  A couple things you can do:

- If you have things that aren't always shown, don't include them in the
default view hierarchy.  Inflate and show them as needed, possibly removing
other things that are no longer shown.

- If you are using complicated hierarchies of layout managers, consider just
writing your own layout manager that does the placement you want.  This can
tremendously improve performance.
