#Material Calendar View

Material Calendar View is a Library based on the GitHub project: Custom Calendar View

I found Custom Calendar View as a really interesting project. But when I started using Custom Calendar View I’ve found that it needed some modifications in order to work as I expected.

So I decided to get involved onto Custom Calendar View to get the modifications I needed. (Thanks to Npanigrahy)

Nowadays my project supports this features:

• Compatibility with Android API 8+
• Swipe gesture-based navigation
• 'Next' and 'Previous' month-based navigation
• Full customization of calendar from XML file, or setters.
• User-allowed to handle events when changes month and day selection using two listeners.
• Show/hide next/previous month overflow days.
• User-allowed modify Typeface of the Calendar View by using setTypeface() method.
• Unlimited customizations for Day of the Month using custom Decorators.
• Add Roboto Fonts files and a Util class to make this fonts accessible. (This probably increase library size)

Features in Process

In order to make the Calendar more customizable and Interactive, the next is a list of some features that I want to add:

• Provide two CalendarViews, one build in Java Calendar API, and the other in JODA Time API
• Synchonize Events with Google Calendar ContentProvider
• Add Ripple Effects when the user touches a day.
• Add two layouts for CalendarView: first one that supports only Swipe navigation without buttons; the second one will support Swipe, and back/next button navigation (actually the default view).

Adding to your Project

Nowadays the library current stable version is 1.2.2.

For Gradle:

Step 1: you must add the JitPack repository to your build file. Type the on your build.gradle at the end of repositories.

  repositories {
    maven { 
	    url "https://jitpack.io"
	}
  }

Step 2: Add the dependency in the form

dependencies {
    compile 'com.github.jonisaa:MaterialCalendarview:v1.2.2'
}

###For Maven:

Step 1: Add the JitPack repository to your maven file.

<repository>
     <id>jitpack.io</id>
     <url>https://jitpack.io</url>
</repository>

Step 2: Add the dependency in the form

<dependency>
     <groupId>com.github.jonisaa</groupId>
     <artifactId>MaterialCalendarView</artifactId>
     <version>v1.2.2</version>
</dependency>

###For SBT:

Step 1: Add it in your build.sbt at the end of resolvers:

resolvers += "jitpack" at "https://jitpack.io"

Step 2: Add the dependency in the form

libraryDependencies += "com.github.jonisaa" % "MaterialCalendarView" % "v1.2.2"

Using Material Calendar View library

This project includes a Sample App that shows you the true power of this library. If you want to know more, feel free to clone, deploy and play with it. Else I’ll give you a little code snippets.

Pay attention to the following:

<com.samsistemas.calendarview.widget.CalendarView
	android:id="@+id/calendar_view"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	android:background="@color/colorPrimary">
</com.samsistemas.calendarview.widget.CalendarView>

The above code snippet will show the simple Calendar View on the default layout. Now, you can use the following attributes if you want to customize the appearance of calendar:

<com.samsistemas.calendarview.widget.CalendarView
    android:id="@+id/calendar_view"
    android:layout_marginTop="56dp"
    android:layout_marginEnd="2dp"
    android:layout_marginLeft="2dp"
    android:layout_marginRight="2dp"
    android:layout_marginStart="2dp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimary"
    app:calendarBackgroundColor="@color/colorPrimary"
    app:calendarTitleTextColor="@color/colorAccent"
    app:currentDayOfMonthColor="@color/white"
    app:dayOfMonthTextColor="@color/white"
    app:dayOfWeekTextColor="@android:color/white"
    app:disabledDayBackgroundColor="@color/colorPrimary"
    app:disabledDayTextColor="@color/colorAccent"
    app:selectedDayBackgroundColor="@color/colorAccent"
    app:titleLayoutBackgroundColor="@color/colorPrimary"
    app:weekLayoutBackgroundColor="@color/colorPrimary"
    app:weekendColor="@color/red"
    app:weekend="saturday|sunday">
</com.samsistemas.calendarview.widget.CalendarView>

The next step is initialize the Calendar View to change the appearance and behavior of calendar using the following methods:

calendarView = (CalendarView) findViewById(R.id.calendar_view);

calendarView.setFirstDayOfWeek(Calendar.MONDAY);
calendarView.setIsOverflowDateVisible(true);
calendarView.setCurrentDay(new Date(System.currentTimeMillis()));
calendarView.setBackButtonColor(R.color.colorAccent);
calendarView.setNextButtonColor(R.color.colorAccent);
calendarView.refreshCalendar(Calendar.getInstance(Locale.getDefault()));
calendarView.setOnDateSelectedListener(new CalendarView.OnDateSelectedListener() {
    @Override
    public void onDateClick(@NonNull Date selectedDate) {
        SimpleDateFormat df = new SimpleDateFormat("dd-MM-yyyy", Locale.getDefault());
        textView.setText(df.format(selectedDate));
    }
});

calendarView.setOnMonthChangedListener(new CalendarView.OnMonthChangedListener() {
    @Override
    public void onMonthChanged(@NonNull Date monthDate) {
        SimpleDateFormat df = new SimpleDateFormat("dd MMMM yyyy", Locale.getDefault());
        if (null != actionBar)
            actionBar.setTitle(df.format(monthDate));
    }
});

final DayView dayView = calendarView.findViewByDate(new Date(System.currentTimeMillis()));
if(null != dayView)
    Toast.makeText(getApplicationContext(), "Today is: " + dayView.getText().toString() + "/" + calendarView.getCurrentMonth() + "/" +  calendarView.getCurrentYear(), Toast.LENGTH_SHORT).show();

Known issues

I’ve made a lot of testand I’ve found no issues. This library I’ve built againts travis and run the sample app in the supported API emulators. But maybe you can find an Issue that i can't detect or whatever.

If you do so, please, let me know. I will be happy to solve it in order to help you.
