A material horizontal calendar view for Android based on RecyclerView.

Installation

The library is hosted on jcenter, add this to your build.gradle:

repositories {
      jcenter()
    }

    dependencies {
      compile 'devs.mulham.horizontalcalendar:horizontalcalendar:1.0.0'
    }

Prerequisites

The minimum API level supported by this library is API 9 (GINGERBREAD).

Usage

Add HorizontalCalendarView to your layout file, for example:

<android.support.design.widget.AppBarLayout
        ............ >

        <devs.mulham.horizontalcalendar.HorizontalCalendarView
            android:id="@+id/calendarView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/colorPrimary"
            app:textColorSelected="#FFFF"/>

</android.support.design.widget.AppBarLayout>

In your Activity, define your start and end dates to set the range of the calendar:

/** end after 1 month from now */
Calendar endDate = Calendar.getInstance();
endDate.add(Calendar.MONTH, 1);

/** start before 1 month from now */
Calendar startDate = Calendar.getInstance();
startDate.add(Calendar.MONTH, -1);

Then setup HorizontalCalendarView using its Builder and pass the id:

HorizontalCalendar horizontalCalendar = new HorizontalCalendar.Builder(this, R.id.calendarView)
                .startDate(startDate.getTime())
                .endDate(endDate.getTime())
                .build();

To listen to date change events you need to set a listener:

horizontalCalendar.setCalendarListener(new HorizontalCalendarListener() {
            @Override
            public void onDateSelected(Date date, int position) {
                //do something
            }
        });

You can also listen to scroll and long press events by overriding each prespective method within HorizontalCalendarListener:

horizontalCalendar.setCalendarListener(new HorizontalCalendarListener() {
            @Override
            public void onDateSelected(Date date, int position) {

            }

            @Override
            public void onCalendarScroll(HorizontalCalendarView calendarView, 
            int dx, int dy) {

            }

            @Override
            public boolean onDateLongClicked(Date date, int position) {
                return true;
            }
        });

Customization

You can customize it directly inside your layout:

<devs.mulham.horizontalcalendar.HorizontalCalendarView
            android:id="@+id/calendarView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/colorPrimary"
            app:textColorNormal="#bababa"
            app:textColorSelected="#FFFF"
            app:selectorColor="#c62828"   // default to colorAccent.
            app:selectedDateBackground="#00ffffff"/>

Or you can do it programmatically in your Activity using the Builder:

HorizontalCalendar horizontalCalendar = new HorizontalCalendar.Builder(this, R.id.calendarView)
                .startDate(startDate.getTime())
                .endDate(endDate.getTime())
                .datesNumberOnScreen(5)   // Number of Dates cells shown on screen (Recommended 5)
                .dayFormat("EEE")     // WeekDay text format
                .dayNumberFormat("dd")  // Date format
                .textColor(Color.LTGRAY, Color.WHITE)    // Text color for none selected Dates, Text color for selected Date.
                .selectedDateBackground(Color.TRANSPARENT)  // Background color of the selected date cell.
                .selectorColor(Color.RED)   // Color of the selection indicator bar (default to colorAccent).
                .build();

Features

  • You can select a specific Date programmatically with the option whether to play the animation or not, with:
horizontalCalendar.selectDate(Date date, boolean immediate); // set immediate to false to ignore animation.
    // or simply
horizontalCalendar.goToday(boolean immediate);
  • Check if two dates' days are equal:
horizontalCalendar.isDatesDaysEquals(Date date1, Date date2);
  • Check if a date is contained in the Calendar:
horizontalCalendar.contains(Date date);
