我有以下视图来展示品牌项目水平滚动...
当我向上滚动时，onLoadFail（）会触发，但如果我评论onLoadFail（），那么每件作品都会如此期待..这里发生了什么！？
使用onLoadFail（）
// Setup product image
Glide.with(context)
.load(item.shopImageURL)
.into(holder.imgBrand)
.onLoadFailed(ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_alert))

没有onLoadFail（）
// Setup product image
Glide.with(context)
.load(item.shopImageURL)
.into(holder.imgBrand)
