Example of Android CalendarView Widget

At first, we will create android application. Then, we will use calendarView widget in this application.

1. Creating New Project

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

Now, we will modify xml and java file to use calendarView widget 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 res/layout/activity_main.xml file. Then, add below code into it.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:gravity="center"
	android:orientation="vertical">

	<CalendarView
		android:id="@+id/calendarView"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:layout_marginBottom="50dp"
		android:layout_marginLeft="50dp"
		android:layout_marginRight="50dp"/>

</LinearLayout>

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

4. Access CalendarView Widget in java file

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

package com.tutorialwing.calendarview;

import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.widget.CalendarView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		CalendarView calendarView = findViewById(R.id.calendarView);
		if (calendarView != null) {
			calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
				@Override
				public void onSelectedDayChange(@NonNull CalendarView view, int year, int month, int dayOfMonth) {
					// Note that months are indexed from 0. So, 0 means January, 1 means february, 2 means march etc.
					String msg = "Selected date is " + dayOfMonth + "/" + (month + 1) + "/" + year;
					Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
				}
			});
		}
	}
}

In MainActivity.java file, we have accessed calendarView widget. Then, we have set a date change listener that shows selected date as toast message.

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

AndroidManifest.xml

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

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.calendarview"
		  xmlns:android="http://schemas.android.com/apk/res/android">

	<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>

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

That’s end of tutorial on Android CalendarView widget.
