Android Hide RelativeLayout Completely

I want to hide a relative layout completely. i have a view with several Layouts i use as buttons with an onClickListener. Now i want to display only those Buttons that i want because sometimes an Object doesnt have all Data. I tried to 开发者_开发问答set visiblity to "4" wich should be "gone" but that didnt do the trick. there still is space reserved for this Layout. What can i do about this?

Thank you.

RelativeLayout.setVisibility(View.GONE);

You should set it to View.GONE which is 8 not 4

to hide:

RelativeLayout.setVisibility(View.INVISIBLE);

to show it again:

RelativeLayout.setVisibility(View.VISIBLE);
