How to give on click listener for footer view in android listview?

This example demonstrate about How to give on click listener for footer view in android listview.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="vertical"
   android:gravity="center_horizontal"
   android:layout_marginTop="30dp"
   tools:context=".MainActivity">
   <ListView
      android:id="@+id/list"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content">
   </ListView>
</LinearLayout>

In the code, we have taken listview to show array values.

Step 3 − Add the following code to src/MainActivity.java

package com.example.myapplication;

import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Gravity;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.HashSet;

public class MainActivity extends AppCompatActivity {
   ListView list;
   String[] names = new String[]{"A", "B", "C"};
   String[] extended = new String[5];

   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      list = findViewById(R.id.list);
      extended[3] = "D";
      extended[4] = "E";
      System.arraycopy(names, 0, extended, 0, names.length);
      HashSet<String> unique = new HashSet<>(Arrays.asList(extended));
      unique.addAll(Arrays.asList(names));
      ArrayList<String> arrayList = new ArrayList<String>(unique);
      ArrayAdapter adapter = new ArrayAdapter<String>(this,
      android.R.layout.simple_list_item_1, arrayList);
      list.setAdapter(adapter);
      final TextView footer = new TextView(this);
      footer.setGravity(Gravity.CENTER);
      footer.setTextSize(30);
      footer.setText("Footer");

      footer.setOnClickListener(new View.OnClickListener() {
      @Override
         public void onClick(View v) {
            footer.setTextColor(Color.parseColor("#FF0000"));
         }
      });
      if (footer != null) {
      list.addFooterView(footer);
      } else {
         throw new NullPointerException("footer is null");
      }
   }
}
