how can i call itemclicklistener inside a switch onclicklistener android -
i creating android application. want when user clicked switch in row call listview's onitemclicklistener. before, tried call listview's itemclicklistener on switch's onclicklistener inside customadapter throws error. if there's no way me achieve desired result, please tell me alternative way. if wondering why need listview's itemclick called inside switch's onclick because itemclick way can rows id use updating rows.
thank in advance. :)
here's code of activity listview:
