Android add RelativeLayout dynamically -

-

i'm trying insert relativelayout dynamically. method works well, layout placed laterally , not under existing

 public void add(view v) {           edittext et=new edittext(context);           relativelayout dynamic_component = new relativelayout(this);           dynamic_component.addview(et);         relativo.addview(dynamic_component);        }

if want layout "dynamic_component" auto-magically placed under existing views of parent layout, "relativo" parent should linearlayout vertical orientation.
