}

here is my recycler Adapter calss :

public class RecAdapter extends RecyclerView.Adapter<RecAdapter.MyViewHolder> {

    private List<Items> items;
    private Context context;

    public RecAdapter(List<Items> items, Context context )
    {
        this.items = items;
        this.context = context;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_item,parent,false);

        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position)  {

        holder.countryname.setText(items.get(position).getCountryname());
        holder.rank.setText(items.get(position).getRank());
        Picasso.with(context)
                .load(items.get(position).getFlag())
                .into(holder.flag);
        holder.setClickListener(new OnItemClickListener() {
            @Override
            public void onClick(View view, int position) {
                Intent intent = new Intent(context , Main2Activity.class);
                context.startActivity(intent);
            }
        });
    }

    @Override
    public int getItemCount() {
        return items.size();
    }

    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

        TextView countryname, rank;
        ImageView flag;
        private OnItemClickListener clickListener;

        public MyViewHolder(View itemView) {
            super(itemView);
            countryname = (TextView) itemView.findViewById(R.id.capital);
            rank = (TextView) itemView.findViewById(R.id.rank);
            flag = (ImageView) itemView.findViewById(R.id.flag);
            itemView.setTag(itemView);
            itemView.setOnClickListener(this);

        }
        public void setClickListener(OnItemClickListener itemClickListener) {
            this.clickListener = itemClickListener;
        }
            @Override
        public void onClick(View view) {
            if (clickListener != null) clickListener.onClick(view, getAdapterPosition());
        }    
    }
}

Answer 1

Add click listener like this:-

View itemView;
Context context;


@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
     itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.card_view, parent, false);
    this.context=parent.getContext();
    return new ViewHolder(itemView);
}
@Override
    public void onBindViewHolder(final ViewHolder holder, int position) {

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(context , Main2Activity.class);
                context.startActivity(intent);
            }
        });
    }
