Solution 1:

Last LinearLayout consists of two objects: Button and LinearLayout. You want it to be divided: 1 unit for button and 2 units for LL. So you should set button layout_weight="1" and LL layout_weight="2". Set also layout_width="fill_parent" (or "0dp" - should act the same as weight will provide proper weight).

You can also put "R" and "Z" to one LL and "arrow", "search" to second LL. Then you will have three objects the same size so put layout_weight="1" to each of them.
