滚动时保存RecyclerView图像状态

Question

我在onBindViewHolder中使用Picasso但是当向上或向下滚动它从互联网上重新加载相同的图像网址时，这会使列表变得如此糟糕和缓慢

所以我想在它第一次加载时保存图像的滚动状态而不再加载它

我怎么能这样做？

onBindViewHolder方法：

@Override
    public void onBindViewHolder(MyCustomAdapter.CustomViewHolder holder, int position) {

            Dishes di = dish.get(position);
            //Download image using picasso library
            Picasso.with(mContext).load(di.getDishImageUrl())
                    .error(R.drawable.ic_error)
                    .placeholder(R.drawable.fav_btn)
                    .into(holder.imageView);

            //Setting text view title
            holder.textView.setText(Html.fromHtml(di.getDishName()));

            View.OnClickListener clickListener = new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                            CustomViewHolder holder = (CustomViewHolder) view.getTag();
                            int position = holder.getPosition();

                            Dishes di = dish.get(position);
                            Toast.makeText(mContext, di.getDishName(), Toast.LENGTH_SHORT).show();
                    }
            };

            //Handle click event on both title and image click
            holder.textView.setOnClickListener(clickListener);
            holder.imageView.setOnClickListener(clickListener);

            holder.textView.setTag(dish.get(position));
            holder.imageView.setTag(dish.get(position));

    }
