how to remove a rule in layoutparams in Android

	You can't remove a rule because all rules are always stored in a fixed-size java array. But you can set a rule to 0. For example

	layoutParams.addRule(RelativeLayout.RIGHT_OF, 0);
	layoutParams.addRule(RelativeLayout.BELOW, R.id.new_ref_LinearLayout);
