68.9 Adding the RecyclerView Adapter

As outlined in detail in the chapter entitled “Working with the RecyclerView and CardView Widgets”, a RecyclerView instance requires an adapter class to provide the data to be displayed.

In the dialog, name the class ProductListAdapter. With the resulting ProductListAdapter.java class loaded into the editor, implement the class as follows:

package com.ebookfrenzy.roomdemo.ui.main;

 

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.TextView;

import com.ebookfrenzy.roomdemo.R;

import androidx.recyclerview.widget.RecyclerView;

import androidx.annotation.NonNull;

import com.ebookfrenzy.roomdemo.Product;

 

import java.util.List;
