How to take filename from db and match it to file in drawable?

Question

Java

Good day everyone!
There is a DB in which (in a separate column) names of files (for example, pic1.jpg etc.) are stored.
In this case, the file itself is located in the drawable folder.
At the moment I have the following in the adapter:
ImageView ob_pic = (ImageView) my_view.findViewById(R.id.ob_pic);
ob_pic.setImageResource(coin.getObPic());
Obviously it doesn't work. It's not clear - how to write the mapping in the adapter correctly?

But just in case, I'll ask: Are you sure this is the right approach?

public int getDrawableRes(String resName) {
        try {
            Field idField = R.drawable.class.getDeclaredField(resName);
            return idField.getInt(null);
        } catch (Exception e) {
            // ...
        }
    }
