    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        val view = inflater.inflate(R.layout.fragment_one, container, false)
        val activity = getActivity() as MainActivity
        widget = view.findViewById(R.id.calendarView) as MaterialCalendarView

        widget.setOnDateChangedListener { widget, date, selected ->
            Toast.makeText(
                activity,
                "current date \n ${date.date}",

widget = view.findViewById(R.id.calendarView) as MaterialCalendarView
widget.setOnDateChangedListener { widget, date, selected ->
            if(selected) {
                Toast.makeText(
                    activity,
                    "current date : ${date.date}",
                    Toast.LENGTH_SHORT
                ).show()
            }
        }
