我想将onClick添加到recyclerView，以便将数据发回表单活动以进行更新数据处理。当此代码中没有适配器时，我如何实现onItemClickListner？
Show_Employees.java：

package com.example.roomdatabaseandroid;
import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.ItemTouchHelper;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;
import com.example.roomdatabaseandroid.DataModel.EmployeeDao;
import com.example.roomdatabaseandroid.DataModel.EmployeeDatabase;
import com.google.android.material.floatingactionbutton.FloatingActionButton;
public class ShowEmployees extends AppCompatActivity {
    private static final int EDIT_COURSE_REQUEST = 2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_show_employees);
        RecyclerView recyclerView;
        FloatingActionButton fab = findViewById(R.id.idFABAdd);
        EmployeeDao employeeDao;
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //starting a new activity for adding a new course and passing a constant value in it.
                Intent intent = new Intent(ShowEmployees.this, MainActivity.class);
                startActivity(intent);
            }
        });
        employeeDao = EmployeeDatabase.getDBInstance(this).employeeDao();
        recyclerView = findViewById(R.id.employeeRecyclerView);
        EmployeeRecycler employeeRecycler = new EmployeeRecycler(employeeDao.getAllEmployee());
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setAdapter(employeeRecycler);
        //below method is use to add swipe to delete method for item of recycler view.
        new ItemTouchHelper(new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
            @Override
            public boolean onMove(@NonNull RecyclerView recyclerView, @NonNull RecyclerView.ViewHolder viewHolder, @NonNull RecyclerView.ViewHolder target) {
                return false;
            }
            @Override
            public void onSwiped(@NonNull RecyclerView.ViewHolder viewHolder, int direction) {
                //on recycler view item swiped then we are deleting the item of our recycler view.
                employeeDao.deleteEmployee(employeeRecycler.data.get(viewHolder.getAdapterPosition()));
                Toast.makeText(ShowEmployees.this, "Employee deleted", Toast.LENGTH_SHORT).show();
            }
        }).attachToRecyclerView(recyclerView);
    }
}

                    R.layout.list_item_1,
                    parent,false
            );
            return new EmployeeViewHolder(view);
        }
    
        @Override
        public void onBindViewHolder(@NonNull EmployeeViewHolder holder, int position) {
            Employee employee = data.get(position);
            holder.imageView.setImageBitmap(DataConverter.convertByteArraytoImage(employee.getImage()));
            holder.firstName.setText(employee.getFirstName());

        public int getItemCount() {
            return data.size();
        }
    
    }
