In our internal company mobile project, FreeQuest – the leave tracking app, we needed to use a calendar widget. Of course, we could use a classic CalendarView but the main problem was that this widget isn’t fully customizable. We had to use two types of calendar widgets: a date picker to select dates and a classic calendar to show absence days in the form of icons below the number of the day. That’s why we created our calendar widget, called MaterialCalendarView and shared it on Github:

In this post, I will describe how to create a simple calendar app using our library.

How to start?

The first thing we have to do is import the Material CalendarView library. To do it, open the project’s build.gradle file and make sure you have defined the jcenter repository like below:

If yes, open the module’s build.gradle file and simply add the following line to the dependency part:

Creating calendar app

Our simple app will consist of three views. The first one will contain the main calendar where we display our notes in the form of icons. The second one will be a view which let us create a new note. The last view will let as a preview that note.

As you can see in the first picture we are using a floating action button. Before you start you have to add compile ‘com.android.support:design:25.3.1’ to your dependency. If you do this you can start creating views:

activity.main.xml

add_note_activity.xml

note_preview_activity.xml

I don’t need to describe all lines of the code because I assume you understand it and I will only focus on com.applandeo.materialcalendarview.CalendarView >. As you can see our widget let you customize its header colour, today’s number colour, selection colour in the picker mode and more. A list of all available tags is in our GitHub’s README. Another important tag is app :datePicker , by default its attribute is set false what means that we use the CalendarView as a standard calendar. If you set it true, as we did in the add_note_activity.xml, you can use it as a date picker that let you select a date and then getting it using the appropriate method I will describe in the further part.

If we have created views already we can take a look at the Java code:

MainActivity

As you may notice in the main class we are using three methods available in our CalendarView: setEvents(), setOnDayClickListener() and setDate(). As the name suggests setEvents() method adds events to the calendar. To use it we have to create a list of EventDay objects and pass them to the method.

EventDay object’s constructor takes two variables – a date in the form of Calendar object and an image resource:

In our sample app we have to add a note to the created event yet. That’s why we have to extend EventDay as in example below:

*Parcelable interface is needed to pass MyEventDays through Intents.

The second method, setOnDayClickListener() is responsible for handling clicks. When the user taps any day row listener will return EventDay object with appropriate date and note.

The third method simply scrolls the calendar to a proper calendar page. In our case to date selected in the AddNoteActivity.

AddNoteActivity

In this class, we are creating MyEventDay objects using another important method that is getSelectedDate(). When the CalendarView is in the picker mode we can use that method to get the selected date in the form of the Calendar object.

NotePreviewActivity

In the last one class we only display informations from MyEventDay object, nothing more.

To sum up

That’s all, simple calendar and simple usage. Of course you can expand that sample app, for instance implement data base or even if you want you can improve our Material CalendarView. It’s open source, feel free!

Material Calendar View

A Material design back port of Android’s CalendarView. The goal is to have a Material look and feel, rather than 100% parity with the platform’s implementation.

Installation

Step 1. Add the JitPack repository to your build file

Step 2. Add the dependency

Usage

1. Add MaterialCalendarView into your layouts or view hierarchy.
2. Set a OnDateSelectedListener or call MaterialCalendarView.getSelectedDates() when you need it.

Documentation

Make sure to check all the documentation available here.

Customization

One of the aims of this library is to be customizable. The many options include:

Events, Highlighting, Custom Selectors, and More!

All of this and more can be done via the decorator api. Please check out the decorator documentation.

Recent Changes

Major Change in 1.5.0

We recently updated to the latest gradle and decided to move over our libraries to the hosting service Jitpack. Please refer to the installation section for more details.

Major Change in 1.4.0

• Breaking Change: setFirstDayOfWeek , setMin/MaxDate , and setCalendarDisplayMode are moved to a State object. This was necessary because it was unclear that these were not simple setters—individually, they were side effecting and triggered full adapter/date range recalculations. Typical usage of the view involves setting all these invariants up front during onCreate and it was unknown to the user that setting all 4 of these would create a lot of waste. Not to mention certain things were side effecting—some would reset the current day or selected date. As a result, the same 4 methods called in a different order could result in a different state, which is bad.
• For most cases you will simply need to replace setting those invariants with:
• mcv.state().edit() .setFirstDayOfWeek(Calendar.WEDNESDAY) .setMinimumDate(CalendarDay.from(2016, 4, 3)) .setMaximumDate(CalendarDay.from(2016, 5, 12)) .setCalendarDisplayMode(CalendarMode.WEEKS) .commit();
• mcv.state().edit() will retain previously set values; mcv.newState() will create a new state using default values. Calling commit will trigger the rebuild of adapters and date ranges. It is recommended these state changes occur as the first modification to MCV (before configuring anything else like current date or selected date); we make no guarantee those modifications will be retained when the state is modified.
• See CUSTOMIZATION_BUILDER for usage details.
• New: setSelectionMode(SELECTION_MODE_RANGE) was added to allow 2 dates to be selected and have the entire range of dates selected. Much thanks to papageorgiouk for his work on this feature.

After that go in the Activity/Fragment where you added the CustomizableCalendar View; here you should specify the first month and the last month, to do this, create a Calendar (located in com.molo17.customizablecalendar.library.model ) object.

An example of CustomizableCalendar init is the following:

How to customize

If you want to customize the components you should create a separeted layout and add the reference to the customizable_calendar View with the tag app:layout=»@layout/your_layout»

An example of a custom layout is the following:

NOTE that ids must not be different from the ones above, so:

• @android:id/primary for HeaderView;
• @android:id/text1 for WeekDaysView;
• @android:id/text2 for SubView;
• @android:id/content for CalendarRecyclerView;

HeaderView

First (red) rectangle of the screenshot above.
It’s a RelativeLayout , you should create your own layout.

WeekDaysView

Third (light blue) rectangle of the screenshot above.
It’s a RecyclerView , the ViewHolder item is already implemented.
You can create your own ViewHolder layout using a RelativeLayout with a TextView that has @android:id/summary as id.

SubView

Second (green) rectangle of the screenshot above.
It’s a RelativeLayout , implemented by default with the name of the month centered.
If you want to create your own layout make sure to have a TextView with id @android:id/summary .

CalendarRecyclerView

Fourth (blue) rectangle of the screenshot above.
It’s a RelativeLayout , implemented by default with a LinearLayout (with a GridLayout inside) for the month and a RelativeLayout for the day.
If you want to create your own month layout you can specify app:month_layout=»@layout/your_layout» for the month and app:cell_layout=»@layout/your_layout» for the day.
Make sure to use @android:id/widget_frame as id for the GridView and @android:id/background , @android:id/startSelectingText , @android:id/stopSelectingText , @android:id/title respectively for single selection background, first day selection background (in multiple selection mode), last day selection background (in multiple selection mode) and the TextView where the day is displayed.

All code customization can be applied using the ViewInteractor .

Here are listed all of the methods with a small description:
