is there anyway to create a full-screen game with multi-resolution?

i means, without top/bottom blank?

for example, the resolution of Milestone is 480x854, in main.cpp,
view~~>create; //here w=480, h=854.
it only displayed a left-bottom-corner game screen, left huge blank space.
when i use this:
view~~>create(320, 480);
it looks fine, only leave blank space at top/bottom.
but here’s the question: is there anyway to let game cover the entire screen?
