Material-Calendar-View is a simple and customizable calendar widget for Android based on Material Design. The widget has two funcionalities: a date picker to select dates (available as an XML widget and a dialog) and a classic calendar. The date picker can work either as a single day picker, many days picker or range picker.

We described a simple usage of the component in this article.

• Material Design
• Single date picker
• Many dates picker
• Range picker
• Events icons
• Fully colors customization
• Customized font

Make sure you are using Java 8 in your project. If not, add below code to build.gradle file:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Make sure you have defined the mavenCentral() repository in project's build.gradle file:

allprojects {
    repositories {
        mavenCentral()
    }
}

Add the dependency to module's build.gradle file:

dependencies {
    implementation 'com.applandeo:material-calendar-view:1.9.2'
}

To your XML layout file add:

<com.applandeo.materialcalendarview.CalendarView
    android:id="@+id/calendarView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

List<CalendarDay> calendarDays = new ArrayList<>();

Calendar calendar = Calendar.getInstance();
CalendarDay calendarDay = new CalendarDay(calendar);
calendarDay.setImageResource(R.drawable.sample_icon);
calendarDays.add(event);

//or if you want to specify event label color
calendarDay.setLabelColor(Color.parseColor("#228B22"));
calendarDays.add(calendarDay);

CalendarView calendarView = (CalendarView) findViewById(R.id.calendarView);
calendarView.setCalendarDays(calendarDays);

You can use our utils method to create Drawable with text

CalendarUtils.getDrawableText(Context context, String text, Typeface typeface, int color, int size);

Take a look at sample_three_icons.xml and adjust it to your project

calendarView.setOnCalendarDayClickListener(new OnCalendarDayClickListener() {
    @Override
    public void onDayClick(CalendarDay calendarDay) {
        Calendar clickedDayCalendar = calendarDay.getCalendar();    
    }
});

...or long click:

calendarView.setOnCalendarDayLongClickListener(new OnCalendarDayLongClickListener() {
    @Override
    public void onDayLongClick(CalendarDay calendarDay) {
        Calendar clickedDayCalendar = calendarDay.getCalendar();
    }
});

If you want to get all selected days, especially if you use multi date or range picker you should use the following code:

List<Calendar> selectedDates = calendarView.getSelectedDates();

...or if you want to get the first selected day, for example in case of using single date picker, you can use:

Calendar selectedDate = calendarView.getFirstSelectedDate();

Calendar calendar = Calendar.getInstance();
calendar.set(2019, 7, 5);

calendarView.setDate(calendar);

Calendar min = Calendar.getInstance();
Calendar max = Calendar.getInstance();

calendarView.setMinimumDate(min);
calendarView.setMaximumDate(max);

List<Calendar> calendars = new ArrayList<>();
calendarView.setDisabledDays(calendars);

List<Calendar> calendars = new ArrayList<>();
calendarView.setHighlightedDays(calendars);

List<Calendar> calendars = new ArrayList<>();
calendarView.setSelectedDates(calendars);

...or if you want to remove selected dates:

calendarView.clearSelectedDays();

• Don't pass more than one calendar object to method above if your calendar type is CalendarView.ONE_DAY_PICKER.
• If your calendar type is CalendarView.RANGE_PICKER you have to pass full dates range. To get it you can use our utils method CalendarUtils.getDatesRange(Calendar firstDay, Calendar lastDay).

calendarView.setOnPreviousPageChangeListener(new OnCalendarPageChangeListener() {
    @Override
    public void onChange() {
        ...
    }
});

calendarView.setOnForwardPageChangeListener(new OnCalendarPageChangeListener() {
    @Override
    public void onChange() {
        ...
    }
});

If you want to use calendar in the picker mode, you have to use the following tags:

• app:type="one_day_picker"
• app:type="many_days_picker"
• app:type="range_picker"

If you want to display event icons in the picker mode, add:

• app:eventsEnabled="true"

• Header color: app:headerColor="[color]"
• Header label color: app:headerLabelColor="[color]"
• Previous button image resource: app:previousButtonSrc="[drawable]"
• Forward button image resource: app:forwardButtonSrc="[drawable]"
• Abbreviations bar color: app:abbreviationsBarColor="[color]"
• Abbreviations labels color: app:abbreviationsLabelsColor="[color]"
• Calendar pages color: app:pagesColor="[color]"
• Selection color in picker mode: app:selectionColor="[color]"
• Selection label color in picker mode: app:selectionLabelColor="[color]"
• Days labels color: app:daysLabelsColor="[color]"
• Color of visible days labels from previous and next month page: app:anotherMonthsDaysLabelsColor="[color]"
• Disabled days labels color: app:disabledDaysLabelsColor="[color]"
• Highlighted days labels color: app:highlightedDaysLabelsColor="[color]"
• Today label color: app:todayLabelColor="[color]"

...or in code:

CalendarView calendarView = (CalendarView) findViewById(R.id.calendarView);
calendarView.setHeaderColor([color]);
calendarView.setHeaderLabelColor([color]);
calendarView.setForwardButtonImage([drawable]);
calendarView.setPreviousButtonImage([drawable]);

To use custom view for calendar cells create XML file (like in example below) and set it using setCalendarDayLayout(@LayoutRes layout: Int) method. XML file must contain TextView with id dayLabel and can contain ImageView with id dayIcon. Do not set colors or textStyle here, it will be overwritten.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/selectableItemBackgroundBorderless"
    android:orientation="vertical">

    <!--REQUIRED-->
    <TextView
        android:id="@+id/dayLabel"
        ... />

    <!--CAN BE SKIPPED-->
    <androidx.appcompat.widget.AppCompatImageView
        android:id="@+id/dayIcon"
        ... />

</LinearLayout>

If you want to customize specyfic cells create list of CalendarDay objects and pass it by setCalendarDays() method like in example below:

val list = listOf(
    CalendarDay(Calendar.getInstance()).apply { 
        labelColor = [color resource]
        backgroundResource = [drawable resource]
        backgroundDrawable = [drawable]
        selectedLabelColor = [color resource]
        selectedBackgroundResource = [drawable resource]
        selectedBackgroundDrawable = [drawable]
    }
)

calendarView.setCalendarDays(list)

In the future CalendarDay will replace EventDay.

• To create font directory Right-click the res folder and go to New > Android resource directory. — The New Resource Directory window appears.
• In the Resource type list, select font, and then click OK.
• Note: The name of the resource directory must be font.
• Add your ttf or otf fonts in font folder. As an example we ad sample_font.ttf and sample_font_bold.ttf
• On a DatePickerBuilder apply .typefaceSrc(R.font.sample_font) for setting sample_font to callendar and its abbreviations.
• Optionally apply .todayTypefaceSrc(R.font.sample_font_bold) to differentiate today date font form the rest of dates in calendar view

If you want to disable the swipe gesture to change the month, you have to use the following tag:

• app:swipeEnabled="false"

...or in code:

calendarView.setSwipeEnabled(false);

If you want to change default first day of week:

• app:firstDayOfWeek="[day]"

...or in code:

calendarView.setFirstDayOfWeek([CalendarWeekDay]);

By default the first day is monday or sunday depending on user location.

To translate months names, abbreviations of days, "TODAY", "OK" and "CANCEL" buttons, just add below tags to your strings.xml file:

<string name="material_calendar_monday">M</string>
<string name="material_calendar_tuesday">T</string>
<string name="material_calendar_wednesday">W</string>
<string name="material_calendar_thursday">T</string>
<string name="material_calendar_friday">F</string>
<string name="material_calendar_saturday">S</string>
<string name="material_calendar_sunday">S</string>

<array name="material_calendar_months_array">
    <item>January</item>
    <item>February</item>
    <item>March</item>
    <item>April</item>
    <item>May</item>
    <item>June</item>
    <item>July</item>
    <item>August</item>
    <item>September</item>
    <item>October</item>
    <item>November</item>
    <item>December</item>
</array>

<string name="material_calendar_today_button">Today</string>
<string name="material_calendar_positive_button">OK</string>
<string name="material_calendar_negative_button">Cancel</string>

DatePickerBuilder builder = new DatePickerBuilder(this, listener)
                .pickerType(CalendarView.ONE_DAY_PICKER);

DatePicker datePicker = builder.build();
datePicker.show();

To use another picker type replace CalendarView.ONE_DAY_PICKER with CalendarView.MANY_DAYS_PICKER or CalendarView.RANGE_PICKER.

private OnSelectDateListener listener = new OnSelectDateListener() {
    @Override
    public void onSelect(List<Calendar> calendars) {
        ...
    }
};
