When my layout loads any view inside of it has a width and height of NaN, it also has a getMeasuredHeight() and getMeasuredWidth() of 0.

At some point getMeasuredHeight() and getMeasuredWidth() (after the layout is laid out I guess) receive useful values.

How can I get the dimensions of anything? How can I watch them change?? When will .width and .height ever not be NaN??? Why can't I make a view hover over the entire screen????

So far I've been polling every 100ms and I feel pretty dumb. Please help.
