How to highlight the current day on "android material-calendar"

Question

I am using material-calendar for android https://github.com/prolificinteractive/material-calendarview

materialCalender = (MaterialCalendarView)v.findViewById(R.id.calendarView);
    materialCalender.state().edit()
            .setFirstDayOfWeek(Calendar.MONDAY)
            .setMinimumDate(CalendarDay.from(1900, 1, 1))
            .setMaximumDate(CalendarDay.from(2100, 12, 31))
            .setCalendarDisplayMode(CalendarMode.MONTHS)
            .commit();

but the calender doesn't show the current day on the calender view. so, how to show that?

Answer 1

try this

    MaterialCalendarView materialCalView = findViewById(R.id.ID_from_your_xml_code);
    materialCalView.setDateSelected(CalendarDay.today(), true);

Answer 2

If you want to set a different color for the current date you have to add a Decorator to your MaterialCalendarView:

calendarView.addDecorator(new DayViewDecorator() {
    @Override
    public boolean shouldDecorate(CalendarDay day) {
        Calendar cal1 = day.getCalendar();
        Calendar cal2 = Calendar.getInstance();

        return (cal1.get(Calendar.ERA) == cal2.get(Calendar.ERA)
                && cal1.get(Calendar.YEAR) == cal2.get(Calendar.YEAR)
                && cal1.get(Calendar.DAY_OF_YEAR) == 
               cal2.get(Calendar.DAY_OF_YEAR));
    }

    @Override
    public void decorate(DayViewFacade view) {
        view.setBackgroundDrawable(ContextCompat.getDrawable(MainActivity.this,R.drawable.selector));
    }
});

Where selector is your custom selector.xml, for example:

 <selector xmlns:android="http://schemas.android.com/apk/res/android"
  android:exitFadeDuration="@android:integer/config_shortAnimTime">

 <item
 android:state_checked="true"
 android:drawable="@color/yourColor"
 />

<item
android:state_pressed="true"
android:drawable="@color/yourColor"
/>

<item android:drawable="@android:color/transparent" />
</selector>
