Respect the distance between icons

[The_Beatnik]

Hi all,
I have a little question....the forum is here for that
I want to put a navigation menu....so i made it my xml with box...all is on the good way however i made it for a fullscreen and when i minimise the size of the window, the icons are too close and the distance between the icons had change.....so the question is: What do i need to put in my xml to respect a distance between my icons on any size of screen?

The xml is there....
THank you very much
