Android upper limit for no of OnclickListeners on an Activity -

i making keyboard app. need know if can assign seperate onclicklistener each button, ie around 70 onclicklisteners on single activity.

is right way it??

implement view.onclicklistener in activity.give different id views.

    public class keyboardactivity extends activity  implements view.onclicklistener{        @override        protected void oncreate(bundle savedinstancestate) {         }        @override        public void onclick(view v) {             //write code corresponding view ids        }     }
