[android-developers] Re: layout problem

change the linearlayout to warp_content and put it in a RelativeLayout/Framelayout and use the proper centering field (centerInParent/layout_gravity)

I've got 3 View elements that i'd like to display at the center

for the life of me - i can't get it to work.

i've tried layout_gravity set to center_vertical - but it does only one element.

maybe i need to group the 3 elements under another layout and then
do a center_vertical on that???
