VerticalCalendar

This calendar library provides a smooth infinite scrolling experience for the user to select a day.

Installation

Import with Gradle:

dependencies {
  implementation 'com.emc.thye:VerticalCalendar:1.0.4'
}

Basic Usage

<com.emc.verticalweekcalendar.VerticalWeekCalendar
    android:id="@+id/verticalCalendar"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    app:customFont="quicksand_bold"
    app:selectedBackground="@color/colorSelectedDayBG"/>
VerticalWeekCalendar calendarView = new VerticalWeekCalendar.Builder()
        .setView(R.id.verticalCalendar)
        .init(this);

Date Click Listener

private GregorianCalendar selected;

calendarView.setOnDateClickListener(new OnDateClickListener() {
    @Override
    public void onCalenderDayClicked(int year, int month, int day) {
        GregorianCalendar selectedDay = new GregorianCalendar(year, month, day);
        if(selected.compareTo(selectedDay) != 0) { 
          //Not the same day is clicked
            selected = selectedDay;
        }
    }
});

Date Watcher

There are two built-in state, SELECTED & DEFAULT that changes the day view's background color. You can also implement your own logic by returning CalendarDay.DEFAULT as the state and use VerticalWeekAdapter.DayViewHolder view as the reference to change the view properties.

calendarView.setDateWatcher(new DateWatcher() {
    @Override
    public int getStateForDate(int year, int month, int day, VerticalWeekAdapter.DayViewHolder view) {
        view.dayView.setBackgroundColor(Color.parseColor("#ff4000"));
        return selected.compareTo(new GregorianCalendar(year, month, day)) == 0 ?
                CalendarDay.SELECTED : CalendarDay.DEFAULT;
    }
});
