your error param checkedid referer identifiant of checked radiobutton inside radiogroup( refer docs) , code :

radiogroup.setoncheckedchangelistener(new oncheckedchangelistener()      {         public void oncheckedchanged(radiogroup group, int checkedid) {             //---displays id of radiobutton checked---             switch(checkedid){             case r.id.btnbasic:                 cabinchoice = "basic";                 break;             case r.id.btndeluxe:                 cabinchoice = "deluxe";                 break;             }         }     });
