Prior to API 17, how do I remove a rule from a layout? I have a RelativeLayout with a number of children. The RelativeLayout is the main layout of my activity. After adding the rule programmatically using 

RelativeLayout.LayoutParams layout = (LayoutParams) theChild.getLayoutParams();
layout.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

I need to remove the rule programmatically at some later time. How would I do this assuming earlier API than 17?

Ah, I figure it out.

RelativeLayout.LayoutParams layout = (LayoutParams) myChild.getLayoutParams();
layout.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 0);

So there is really no removeRule until API 17.

    This answer wasn't immediately clear to me. In Android code, removeRule(rule) basically does the same thing as addRule(rule, 0), which is why the answer shown here works. – greg7gkb Jan 21 '15 at 20:23

Depending on the situation, in my case I created new LayoutParams and then added rules which were needed
