Below is an example of how to use this technique in List Items. To show that this works, I have created a simple ListView which have a text view.

Here, if a user presses the Item in the list. So how this is works? We have implemented a function which will be called whenever the button gets hits.

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
	@Override
	public void onItemClick(AdapterView <?> parent, View view, int position, long id) {
		Toast.makeText(MainActivity.this, items.get(position)+"", Toast.LENGTH_SHORT).show();
	}
});

With the above function, you need to put your code inside onItemClick block.

Java file:

package com.example.vikramdiwakar.myapplication;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {
    ListView list;
    ArrayList<String> items;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_list);

        list = (ListView) findViewById(R.id.list);
        items = new ArrayList<String>();
        items.add("ABHISHEK SHARMA");
        items.add("MANU JEMINI");
        ArrayAdapter<String> itemsAdapter =
                new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, items);

        list.setAdapter(itemsAdapter);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(MainActivity.this, items.get(position)+"", Toast.LENGTH_SHORT).show();
            }
        });
    }
}

XML file:

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

    <ListView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/list"
        android:layout_gravity="center_horizontal" />
</LinearLayout>

Menifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.vikramdiwakar.myapplication">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Output
