Set onItemClickListener inside onBindViewHolder() with RecyclerView.Adapter

Question

I have a custom object :

Student.class

public class Student {
  private String name;
  private String age;

  public String getName() {
    return name;

Simplest way is holding single ItemClickListener inside your Adapter:

public class WalletListRecyclerAdapter extends RecyclerView.Adapter {
    private List wallets;
    private ItemClickListener itemClickListener;

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        Wallet wallet = wallets.get(position);

        holder.root.setOnClickListener(v -> {
            if (itemClickListener != null)
                itemClickListener.onClick(holder.root, wallet);
        });
    }

    static class ViewHolder extends RecyclerView.ViewHolder {
        View root;

        public ViewHolder(View v) {
            super(v);
            root = v;
        }
    }


    public void setItemClickListener(ItemClickListener itemClickListener) {
        this.itemClickListener = itemClickListener;
    }

    public interface ItemClickListener {
        void onClick(View view, Wallet wallet);
    }
}

In Activity:

walletsAdapter = new WalletListRecyclerAdapter();
walletsAdapter.setItemClickListener((view, wallet) -> {
    Intent intent = new Intent(this, WalletActivity.class);
    intent.putExtra(Const.KEY_WALLET, wallet);
    startActivity(intent);
});
