Android : Add events to Android studio calendarview

So I'm practicing getting the hang of android studio by making simple programs. I have created a calendar using the calendarview api and the code is:

package com.try.androidcalendarviewexample;

import android.annotation.TargetApi;
import android.os.Build;
import android.os.Bundle;
import android.widget.CalendarView;
import android.widget.CalendarView.OnDateChangeListener;
import android.widget.Toast;
import android.app.Activity;

public class AndroidCalendarviewExample extends Activity {
CalendarView calendar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //sets the main layout of the activity
    setContentView(R.layout.activity_main);

    //initializes the calendarview
    initializeCalendar();
}

@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public void initializeCalendar() {
    calendar = (CalendarView) findViewById(R.id.calendar);

    // sets whether to show the week number.
    calendar.setShowWeekNumber(false);

    // sets the first day of week according to Calendar.
    // here we set Monday as the first day of the Calendar
    calendar.setFirstDayOfWeek(2);

    //The background color for the selected week.
    calendar.setSelectedWeekBackgroundColor(getResources().getColor(R.color.green));

    //sets the color for the dates of an unfocused month. 
    calendar.setUnfocusedMonthDateColor(getResources().getColor(R.color.transparent));

    //sets the color for the separator line between weeks.
    calendar.setWeekSeparatorLineColor(getResources().getColor(R.color.transparent));

    //sets the color for the vertical bar shown at the beginning and at the end of the selected date.
    calendar.setSelectedDateVerticalBar(R.color.darkgreen);

    //sets the listener to be notified upon selected date change.
    calendar.setOnDateChangeListener(new OnDateChangeListener() {

        //show the selected date as a toast
        @Override
        public void onSelectedDayChange(CalendarView view, int year, int month, int day) {
            Toast.makeText(getApplicationContext(), day + "/" + month + "/" + year, Toast.LENGTH_LONG).show();
        }
    });
}
}

Currently this just displays the a simple calendar view full screen and lets you scroll down through the months. I was wondering how I may add events to this code. Is there any simple API that could be used to extend this calendar to holding events too? Or should I be using something else for that
