Source Code Android RecyclerView

After import the first step of add the dependency in build.gradle file. Open default file of MainActivity.java class and insert the following below code to initiate the homepage.

package com.rohitss.rvclick;

import android.os.Bundle;
import android.view.View;
import android.widget.Toast;

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

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {
    private ArrayList mTestItemList;
    private View.OnClickListener onItemClickListener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            //TODO: Step 4 of 4: Finally call getTag() on the view.
            // This viewHolder will have all required values.
            RecyclerView.ViewHolder viewHolder = (RecyclerView.ViewHolder) view.getTag();
            int position = viewHolder.getAdapterPosition();
            // viewHolder.getItemId();
            // viewHolder.getItemViewType();
            // viewHolder.itemView;
            TestItem thisItem = mTestItemList.get(position);
            Toast.makeText(MainActivity.this, "You Clicked: " + thisItem.getTitle(), Toast.LENGTH_SHORT).show();
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        RecyclerView recyclerView = findViewById(R.id.recycler_view);

        initDummyData();

        MyRecyclerAdapter recyclerViewAdapter = new MyRecyclerAdapter(mTestItemList);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setAdapter(recyclerViewAdapter);
        //TODO: Step 1 of 4: Create and set OnItemClickListener to the adapter.
        recyclerViewAdapter.setOnItemClickListener(onItemClickListener);

    }

    private void initDummyData() {
        mTestItemList = new ArrayList<>();
        TestItem testItem;

        testItem = new TestItem("Test Item 1", "This is test item 1");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 2", "This is test item 2");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 3", "This is test item 3");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 4", "This is test item 4");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 5", "This is test item 5");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 6", "This is test item 6");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 7", "This is test item 7");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 8", "This is test item 8");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 9", "This is test item 9");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 10", "This is test item 10");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 11", "This is test item 11");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 12", "This is test item 12");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 13", "This is test item 13");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 14", "This is test item 14");
        mTestItemList.add(testItem);

        testItem = new TestItem("Test Item 15", "This is test item 15");
        mTestItemList.add(testItem);
    }
}

List the Data RecyclerView

First we need to develop the data in recycler formate view. When user click the data it showing another one activity. ListView is very user friendly that’s why most of end user like this development. Here we can also implement scrollview concept. The class file is

package com.rohitss.rvclick;

public class TestItem {
    private String title;
    private String description;

    public TestItem(String title, String description) {
        this.title = title;
        this.description = description;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }
}
