try this

onclicklistener checkboxlistener; checkboxlistener =new onclicklistener() { @override public void onclick(view arg0) { // todo auto-generated method stub if(checkbox1.ischecked()) { toast.maketext(getbasecontext(), "something", toast.length_short).show(); } } }; checkbox1.setonclicklistener(checkboxlistener);
