Recyclerview 往回滑怎么停止重复加载图片

初入 android 的萌新向大神请教一下，弄了一个水平滑动的 recyclerview 问题是加载过的图片，往回之后又看过它重新加载了，怎么让它不加载啊 我直接上部分代码，直观点，用的 databinding 加载数据和 adapter

@BindingAdapter({"bind:imageUrl","bind:error"}) public static void ladImage(ImageView view, String url, Drawable error){ Glide.with(view.getContext()).load(UriUtil.completeImgUrl(url)).error(error).into(view); } @BindingAdapter("bind:data") public static void setData(RecyclerView recyclerView, List<ItemData> data){ setHorizontalRVdata(recyclerView, data); } 下面是 adapter 部分 @Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { B binding = DataBindingUtil.inflate(LayoutInflater.from(mContext), getLayoutId(viewType), parent, false); return new BaseViewHolder(binding.getRoot()); } @Override public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { B binding = DataBindingUtil.getBinding(holder.itemView); onBindItem(binding, items.get(position)); }
