RecyclerView With CLICK LISTENER! (ANDROID)

Heres how you create a recyclerView with OnClickListener in JAVA.

Firstly lets initiate our recycler layout in our main layout file:

activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">


  <androidx.recyclerview.widget.RecyclerView
      android:id="@+id/recyclerView"
      android:layout_width="match_parent"
      android:layout_height="match_parent"/>


</RelativeLayout>

Lets create our Recycler View Layout:

recycler_layout.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/textView"
        android:text="sample"
        android:textColor="#ffffff"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"/>

</RelativeLayout>

And lets create our adapter Like this:

RecyclerAdapter.java

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> {

    Context mContext;
    List<String> listItems;

    public RecyclerAdapter(Context mContext, List<String> listItems) {
        this.mContext = mContext;
        this.listItems = listItems;
    }

    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater inflator = LayoutInflater.from(mContext);
        View view = inflator.inflate(R.layout.recycler_layout, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        holder.bind(listItems, position);
    }

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

    class ViewHolder extends RecyclerView.ViewHolder {

        TextView textView;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.textView);
        }

        public void bind(List<String> listItems, int position) {
            textView.setText(listItems.get(position));
            textView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    Toast.makeText(mContext, "item: " + listItems.get(position), Toast.LENGTH_SHORT).show();
                }
            });
        }
    }
}

and Finally Our MainActiivty.java look like this.

package com.example.oddtocode;

import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;


import android.os.Bundle;

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

public class MainActivity extends AppCompatActivity {

    RecyclerView recyclerView;
    RecyclerAdapter adapter;
    List<String> listItems;

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

        recyclerView = findViewById(R.id.recyclerView);

        listItems = new ArrayList<>();
        listItems.add("Item 1");
        listItems.add("Item 2");
        listItems.add("Item 3");
        listItems.add("Item 4");
        listItems.add("Item 5");
        listItems.add("Item 6");
        listItems.add("Item 7");
        listItems.add("Item 8");
        listItems.add("Item 9");
        listItems.add("Item 10");
        listItems.add("Item 11");
        listItems.add("Item 12");
        listItems.add("Item 13");
        listItems.add("Item 14");
        listItems.add("Item 15");
        listItems.add("Item 16");
        listItems.add("Item 17");
        listItems.add("Item 18");
        listItems.add("Item 19");
        listItems.add("Item 20");

        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        adapter = new RecyclerAdapter(getApplicationContext(),listItems);
        recyclerView.setAdapter(adapter);


    }
}

and yes finally that's how our app looks like:

That's how recyclerView with click listener can be created with Click Listener.
