Android example using RecyclerView with CardView

The former post show "Android CardView example", It can be embedded in RecyclerView.

Modify from last exercise of RecyclerView, "onDraw() and onDrawOver() of ItemDecoration for RecyclerView".

Create layout of the CardView, layout/layout_cardview.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    card_view:cardCornerRadius="20sp"
    card_view:cardElevation="5sp">

    <TextView
        android:id="@+id/card_item_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="40dp"/>

</android.support.v7.widget.CardView>

Modify constructor of ItemHolder() in com.example.androidrecyclerview.RecyclerViewAdapter.java, ItemHolder(CardView cView, RecyclerViewAdapter parent), to include CardView. And also modify the method onCreateViewHolder(ViewGroup parent, int viewType).

com.example.androidrecyclerview.RecyclerViewAdapter.java

package com.example.androidrecyclerview;

import android.content.Context;
import android.support.v7.widget.CardView;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import java.util.ArrayList;
import java.util.List;

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ItemHolder> {

    private List<String> itemsName;
    private OnItemClickListener onItemClickListener;
    private LayoutInflater layoutInflater;

    public RecyclerViewAdapter(Context context){
        layoutInflater = LayoutInflater.from(context);
        itemsName = new ArrayList<String>();
    }

    @Override
    public RecyclerViewAdapter.ItemHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        //View itemView = layoutInflater.inflate(R.layout.layout_item, parent, false);
        //return new ItemHolder(itemView, this);
        CardView itemCardView = (CardView)layoutInflater.inflate(R.layout.layout_cardview, parent, false);
        return new ItemHolder(itemCardView, this);
    }

    @Override
    public void onBindViewHolder(RecyclerViewAdapter.ItemHolder holder, int position) {
        holder.setItemName(itemsName.get(position));
    }

    @Override
    public int getItemCount() {
        return itemsName.size();
    }

    public void setOnItemClickListener(OnItemClickListener listener){
        onItemClickListener = listener;
    }

    public OnItemClickListener getOnItemClickListener(){
        return onItemClickListener;
    }

    public interface OnItemClickListener{
        public void onItemClick(ItemHolder item, int position);
    }

    public void add(int location, String iName){
        itemsName.add(location, iName);
        notifyItemInserted(location);
    }

    public void remove(int location){
        if(location >= itemsName.size())
            return;

        itemsName.remove(location);
        notifyItemRemoved(location);
    }

    public static class ItemHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

        private RecyclerViewAdapter parent;
        TextView textItemName;

        private CardView cardView;

        /*
        public ItemHolder(View itemView, RecyclerViewAdapter parent) {
            super(itemView);
            itemView.setOnClickListener(this);
            this.parent = parent;
            textItemName = (TextView) itemView.findViewById(R.id.item_name);
        }
        */

        public ItemHolder(CardView cView, RecyclerViewAdapter parent) {
            super(cView);
            cardView = cView;
            cardView.setOnClickListener(this);
            this.parent = parent;
            textItemName = (TextView) cardView.findViewById(R.id.card_item_name);
        }

        public void setItemName(CharSequence name){
            textItemName.setText(name);
        }

        public CharSequence getItemName(){
            return textItemName.getText();
        }

        @Override
        public void onClick(View v) {
            final OnItemClickListener listener = parent.getOnItemClickListener();
            if(listener != null){
                listener.onItemClick(this, getPosition());
            }
        }
    }
}
