So far you have created an Adapter for the RecyclerView. You have also added a View Holder.
In order to display data you need to write code to the onBindViewHolder method. This method will map the data to the Card View.
@Override public void onBindViewHolder(ViewHolder holder, int position) { CardView cardView = holder.mCardView; TextView cardText = (TextView) cardView.findViewById(R.id.cardTextId); cardText.setText(textData[position]); }
