Как да изпратите идентификатор на autocompletetextview?

В моето приложение използвах autocompletetextview за извличане на данни, данните, които показвам, използват json, сега autocompletetextview работи добре, но това, което искам, е след като получа име в моя autocompletetextview, искам да изпратя идентификатор на категория, но той изпраща име..следва е моят отговор..и кодът ми на фрагмент е тук..Autocompletetextview не работи

{
 "category":
  [
   {
      "id":"4",
      "name":"cat1"
   },
   {
      "id":"7",
    "name":"aditya"}
   ]
}
