ExpandableWeightLayout incorrectly calculates expanding height

[Josvanegmond]

ExpandableWeightLayout seems to only work if you have a view below with an equal weight. Without that 'balancing' view, the accelerator seems to expand to an infinite size (linearaccelerator accelerates quadratically, which becomes visible if you add a view below the expandablelayout with a weight of 0.01). If you're bound to have a 'balancing' view with the same weight, you can't have an expandablelayout filling the entire screen.
