Android CalanderView Kotlin

Example of using CalendarView in an Android application

Here is the tutorial for Java

There Are Some Common Attributes for CalanderView :

Step 1:
File open res/layout/activity_main.xml file −

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <CalendarView
        android:id="@+id/calendarView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</RelativeLayout>

Step 2:

File open com.microappvalley.newtestproject/MainActivity.kt file −

package com.microappvalley.newtestproject

import android.annotation.SuppressLint
import android.os.Bundle
import android.widget.CalendarView
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {

    @SuppressLint("MissingInflatedId")
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        var calendarView:CalendarView=findViewById(R.id.calendarView)

        calendarView.setOnDateChangeListener { view, year, month, dayOfMonth ->

            // Display the selected date
            val selectedDate = "Selected Date: " + (month + 1) + "/" + dayOfMonth + "/" + year
            Toast.makeText(this@MainActivity,selectedDate,Toast.LENGTH_LONG).show()
        }

    }
}

Open Device Manager, run the emulator, and  then run the application. Next, check the working output and check the output  you declared in your code.
