Android - How to stop images reloading in Recyclerview when scrolling

Question

I was creating an app for loading images from internet in cards. I am using Recyclerview for listing purpose. For downloading images, I have tried Picasso, universal-image-downloader and other custom methods but everywhere I have this problem:

Whenever I scroll down and up the images in imageview are getting reloaded. I have even kept a condition to check if the imageview contains an image but that also doesn't seem to work or my code may be faulty. But I am not able to find a solution to this problem. Below I have attached the 'onBindViewHolder' function of my code which I think is the problematic part. Here images is a string arraylist containing image urls.

public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {            
        View view = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.default_card, parent, false);

        ViewHolder viewHolder;
        viewHolder = new ViewHolder(view);

        return viewHolder;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {            
        String url = images.get(position);

        if (holder.imgView.getDrawable() != null) {
            //Do Nothing
        } else {                
            ImageLoader.getInstance().displayImage(url, holder.imgView);               
        }
    }

You can use this to solve your issue.

mRecyclerView.getRecycledViewPool().setMaxRecycledViews(0, 0);
