How to show the all the name in attendance in firebase?

Question

As question, how to display all the checkInName of the event? From the code below, I'm already able to get the event name from

String attendance = intent.getStringExtra("Attendance"); 

But how to display it inside the recycle view?

package com.example.edward.neweventmanagementsystem;

import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.example.edward.neweventmanagementsystem.Model.AttendanceInfo;
import com.example.edward.neweventmanagementsystem.ViewHolder.MenuViewHolder;
import com.firebase.ui.database.FirebaseRecyclerAdapter;
import com.firebase.ui.database.FirebaseRecyclerOptions;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;
import com.google.firebase.database.Query;

public class attendanceListMainList extends AppCompatActivity {

    RecyclerView recycle_menu;
    RecyclerView.LayoutManager layoutManager;
    private DatabaseReference mDatabaseReference;
    FirebaseRecyclerAdapter<AttendanceInfo, MenuViewHolder> adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_attendance_list_main_list);

        mDatabaseReference = FirebaseDatabase.getInstance().getReference().child("AttendanceRecord");

        searchAttendance();

    }

    public void searchAttendance() {

        Intent intent = getIntent();
        String attendance=  intent.getStringExtra("Attendance");
        System.out.println("Test in StaffAttendanceRecordTable: "+attendance);

    }
    @Override
    public void onBackPressed() {
        Intent intent = new Intent(this, StaffAttendanceRecordTable.class);
        startActivity(intent);
    }

}
