just write below code add together event in list view

b.setonclicklistener(new onclicklistener() { public void onclick(view v) { // todo auto-generated method stub string name=ed.gettext().tostring(); list_view_obj.add(name); //call adapter class , pass string list_view_obj.setadapter(your adapter's obj); your_adapter_obj.notifydatasetchanged(); } });

hope got it.
