Not sure what or why this is happening. Here is the portion of the code i am having problems with.

        public TextView mUrl;
        public TextView mTitle;
        public TextView mDate;
        public TextView mAuthor;
        public ImageView mThumbnail;

        public ContentViewHolder(View itemView) {
            super(itemView);
            mUrl= (TextView) itemView.findViewById(R.id.url);
            mTitle = (TextView) itemView.findViewById(R.id.title);
            mDate = (TextView) itemView.findViewById(R.id.date);
            mAuthor = (TextView) itemView.findViewById(R.id.author);

            mUrl.setText(bloginfo.getUrl());
            mTitle.setText(bloginfo.getTitle());
            mDate.setText(bloginfo.getDate());
            mAuthor.setText(bloginfo.getAuthor());

Hi Alex,

This is somewhat of a more complex issue.

A RecylerView or RecylerView.Adapter does not have Context. You usually get them from Activity or Application classes. The easiest way to pass the context is to pass it through your constructor.

If you need more details of how this is done, can you paste your entire Recycler Adapter file?

Try this link:

Context can be a little difficult to understand at first. It will click at some point. I still learn things about it as well.
