Android Question Create panels with shortcut's in function of rights

Hi,

I need to create panels with shortcut's to certain functions in the app based on the rights of the user.
The shortcut's are now displayed on a customlistview.
One user could have 4 shortcuts and another user could have 12.
What would be the easiest way to make the shortcuts visible in 3 rows without empty spots for features that are not available to the user?

Thanks.
