55.6 Creating the RecyclerView Adapter

As outlined in the previous chapter, the RecyclerView needs to have an adapter to handle the creation of the list items. Add this new class to the project by right-clicking on the app -> java -> com.ebookfrenzy.carddemo entry in the Project tool window and selecting the New -> Kotlin File/Class menu option. In the new class dialog, enter RecyclerAdapter into the Name field and select Class from the list before tapping the Return keyboard key to create the new Kotlin class file.

Edit the new RecyclerAdapter.kt file to add some import directives and to declare that the class now extends RecyclerView.Adapter. Rather than create a separate class to provide the data to be displayed, some basic arrays will also be added to the adapter to act as the data for the app:

package com.ebookfrenzy.carddemo

 

import android.view.LayoutInflater

import android.widget.ImageView

import android.widget.TextView

import android.view...
