This example demonstrates how to add calendar events in Android App using Kotlin?

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="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:padding="8dp"    tools:context=".MainActivity">    <TextView       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_centerHorizontal="true"       android:layout_marginTop="50dp"       android:text="Tutorials Point"       android:textAlignment="center"       android:textColor="@android:color/holo_green_dark"       android:textSize="32sp"       android:textStyle="bold" />    <Button       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_below="@+id/textView"       android:layout_centerInParent="true"       android:onClick="addCalendarEvent"       android:text="Add Calendar Event" />    <TextView       android:id="@+id/textView"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_centerInParent="true"       android:text="Calendar Event In Android"       android:textColor="@android:color/background_dark"       android:textSize="18sp"       android:textStyle="bold" /> </RelativeLayout>

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

import android.content.Intent import android.os.Bundle import android.view.View import androidx.appcompat.app.AppCompatActivity import java.util.* class MainActivity : AppCompatActivity() {    override fun onCreate(savedInstanceState: Bundle?) {       super.onCreate(savedInstanceState)       setContentView(R.layout.activity_main)       title = "KotlinApp"    }    fun addCalendarEvent(view: View) {       val calendarEvent: Calendar = Calendar.getInstance()       val intent = Intent(Intent.ACTION_EDIT)       intent.type = "vnd.android.cursor.item/event"       intent.putExtra("beginTime", calendarEvent.timeInMillis)       intent.putExtra("allDay", true)       import android.content.Intent       import android.os.Bundle       import android.view.View       import androidx.appcompat.app.AppCompatActivity       import java.util.*       class MainActivity : AppCompatActivity() {          override fun onCreate(savedInstanceState: Bundle?) {          super.onCreate(savedInstanceState)          setContentView(R.layout.activity_main)          title = "KotlinApp"       }       fun addCalendarEvent(view: View) {          val calendarEvent: Calendar = Calendar.getInstance()          val intent = Intent(Intent.ACTION_EDIT)          intent.type = "vnd.android.cursor.item/event"          intent.putExtra("beginTime", calendarEvent.timeInMillis)          intent.putExtra("allDay", true)          intent.putExtra("rule", "FREQ=YEARLY")          intent.putExtra("endTime", calendarEvent.timeInMillis + 60 * 60 * 1000)          intent.putExtra("title", "Calendar Event")          startActivity(intent)    } }

Step 4 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.q11">    <application       android:allowBackup="true"       android:icon="@mipmap/ic_launcher"       android:label="@string/app_name"       android:roundIcon="@mipmap/ic_launcher_round"       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>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click the Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen
