SimpleCalendar

😃 What should The Simple Calendar do.

---

• Events can be displayed on the calendar.

  simpleCalendar.setOnEventListener((startTimestamp, endTimestamp) ->
    {
      // Feb
      // +------ ... ------+
      // | 1 | 2 | ... | 7 | // StartTimestamp is '1 Feb' at unixtime
      // | ...             |
      // | ...         |28 |
      // | 1 | ...         |
      // |     ...     |14 | // EndTimestamp is '14 Mar' at unixtime
      // +------ ... ------+
      // TODO return List events from startTimestamp to endTimeStamp
      // DayEvent object can set title, color of background, color of title and time.
      return (List<DayEvent>)list;
    }
  );

---

• Customize the color of your calendar and events to xml

---

• Add a specific day as a holiday.

  simpleCalendar.setOnHolidayListener((year, month) -> {
      // New Year Holiday (1/Jan) of Korea.
      if( month == 1 ) return Collections.singletonList(1L);
      // TODO write your holiday format (day list)
      return null;
  });

---

• Know the date that you clicked in the calendar.

  simpleCalendar.setOnDayClickListener(time -> {
    Log.i(MainActivity.class.getSimpleName(), "click on : " + WeekFormat.getDateStringBestFmt(new Date(time), "yyyy MM dd"));
  
    list.add(new DayEvent("sample", time, time));
    simpleCalendar.notifyDataSetChanged();
  
    // TODO write what do you do
  });

---

• Know what month it is whenever you swipe.

  simpleCalendar.setOnSwipeMonthListener(time ->
        // TODO When changed the page, write for what to do
        Toast.makeText(MainActivity.this, "swipe on : " + WeekFormat.getDateStringBestFmt(new Date(time), "MM"), Toast.LENGTH_SHORT).show()
  );

---

• Move a calendar to a specific date.

  c.setTimeInMillis(today);
  c.set(Calendar.MONTH, 3); // Maple
  simpleCalendar.setDate(c.getTimeInMillis());
