я создал вид Recycler, который показывает список элементов, однако, отображаются только первые 10 лучших, если я перетаскиваю список, повторяю случайным образом первые 1 ~ 10 элементов, он должен отображаться так
1
2
3
4
5
6
7
8
9
10
11
12
13
....
но
1
2
3
4
5
6
7
8
9
10 (пока здесь хорошо)
5
3
6
.... (повторяется только от 1 до 10)
я прикрепил код, может кто-нибудь дать мне совет ??
