But the problem is that when I scrolled it the states of image button changes to load time images.

Answer 1

确保在onBindViewHolder上设置收藏夹/收藏夹。

Answer 2

RecyclerView efficiently recycles views while you scroll.

when you maintain this kind of scenario, where image view can have Fav or UnFav images. you need to maintain both in onBindVIewHolder() method such as

if (isFav) {
viewHolder.yourImage.setBackgroundDrawable(FavImage);
} else {
viewHolder.yourImage.setBackgroundDrawable(UnFavImage);
}

Answer 3

尝试在每种情况下在#onBindViewHolder上设置图像（不要假设您知道当前状态）。
