こんにちは私はAPIからjsonからidを取得しようとしています。ユーザーをクリックすると、クリックされたユーザーのjsonからIDが取得されます。json recycleview retrofit2からidを取得
マイアプリは次のようになります。
JSON：
[
{
"id": 6,
"name": "Tester 1",
"online": "0",
"profileimg": "https://s-media-cache-ak0.pinimg.com/736x/af/9c/6a/af9c6a69e7556ffcae42de85735f5a97.jpg",
"distancekm": 16286,
"distancem": 10119
},
{
"id": 15,
"name": "Tester 2",
"online": "0",
"profileimg": "http://assets1.ignimgs.com/2014/10/07/ironmanjpg-affbef_1280w.jpg",
"distancekm": 6216,
"distancem": 3863
},
{
"id": 22,
"name": "Tester 3",
"online": "0",
"profileimg": "",
"distancekm": 1,
"distancem": 1
},
{
"id": 23,
"name": "Tester 4",
