How to get a context in a recycler view adapter

You have a few options here:

1. Pass Context as an argument to FeedAdapter and keep it as class field
2. Use dependency injection to inject Context when you need it. I strongly suggest reading about it. There is a great tool for that — Dagger by Square

3. Get it from any View object. In your case this might work for you:

   holder.pub_image.getContext()

   As pub_image is a ImageView.
