Example of Android CalendarView Using Kotlin

At first, we will create android application. Then, we will use calendarView using kotlin in the application.

1. Creating New Project in Kotlin

Follow steps below to create new project. Please ignore the steps if you have already created the project.

Step Description
1. Open Android Studio.
2. Go to File => New => New Project. Write application name as CalendarView. Then, check Include Kotlin Support and click next button.
3. Select minimum SDK you need. However, we have selected 17 as minimum SDK. Then, click next button
4. Then, select Empty Activity => click next => click finish.
5. You will get a newly created project successfully if you have followed steps properly.

Since we have a project now, we will modify xml and other files to use calendarView using kotlin in the application.

2. Modify values folder

No values folders have been modified. So, we are not going to mention them here.

3. Use CalendarView Widget in xml file

Open src/main/res/layout/activity_main.xml file and add below code into it.

<?xml version="1.0" encoding="utf-8"?>



In activity_main.xml file, we have defined calendarView widget. Now, we will access this calendarView using kotlin file to perform some operations on it.

4. Access CalendarView Widget in Kotlin file

Open src/main/java/com.tutorialwing.calendarview/MainActivity.kt file and add below code into it.

package com.tutorialwing.calendarview

import android.os.Bundle
import android.widget.CalendarView
import android.widget.Toast

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {

        val calendarView = findViewById<CalendarView>(
        calendarView?.setOnDateChangeListener { view, year, month, dayOfMonth ->
            // Note that months are indexed from 0. So, 0 means January, 1 means february, 2 means march etc.
            val msg = "Selected date is " + dayOfMonth + "/" + (month + 1) + "/" + year
            Toast.makeText(this@MainActivity, msg, Toast.LENGTH_SHORT).show()

We have accessed calendarView using kotlin file (i.e. MainActivity.kt file) in the application. Then, we have set date change listener to display selected date as toast message in the application.

Since AndroidManifest.xml file is very important in any android application, we are also going to see the content inside this file.

AndroidManifest.xml file

Code inside main/AndroidManifest.xml file is as below.

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.calendarview"

		<activity android:name=".MainActivity">
				<action android:name="android.intent.action.MAIN"/>

				<category android:name="android.intent.category.LAUNCHER"/>


When we run the program, we will get output as shown above.

That’s end of our tutorial on Android calendarView using Kotlin.
