Before getting into the example, we should know what is date picker and how does it work in android. The date picker is a subclass of frame layout and it allows to select the date, month and year.

This example demonstrates how to use android date change listener.

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"?>
<RelativeLayout xmlns:android=""
      android:layout_marginBottom="36dp" />

In the above code, we have declare date picker to select the date. when you select the date it going to show current date on Toast message.

Step 3 − Add the following code to src/

package com.example.andy.myapplication;
import android.annotation.TargetApi;
import android.os.Build;
import android.os.Bundle;
import android.widget.DatePicker;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   protected void onCreate(Bundle savedInstanceState) {
      DatePicker datePicker = findViewById(;
      datePicker.setOnDateChangedListener(new DatePicker.OnDateChangedListener() {
         public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            Toast.makeText(MainActivity.this," You are changed date is : "+dayOfMonth +" -  "+monthOfYear+ " - "+year,Toast.LENGTH_LONG).show();

In the above code when you change the date using datechangedlistener, it going to show changed date, month and year on Toast message.

Step 4 − No need to change manifest.xml.

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer.

Select your mobile device as an option and then check your mobile device which will display your default screen −
