    return viewHolder;
}

@Override
public void onBindViewHolder(NotificationsAdapter.ViewHolder holder, int position) {

    holder.notificationStatus.setText(notificationData.getNotificationStatus());
    holder.orderDescription.setText(notificationData.getNotificationLabel());

    if ("true".equals(notificationData.getReadStatus())) {
        holder.root.setBackgroundColor(mContext.getResources().getColor(R.color.white));
        holder.notificationStatus.setTypeface(Typeface.create("sans-serif-light", …
