Android CalendarView to show events

Question

I want to show a calendar with events using different colors on a date similar to setting the default calendar. But I do not see such an API in the default calendar view.

Can someone direct me in the right direction how to do this? Should I extend the default calendar and add my own features? Or should I use 5x5 text fields with PageViewer and snippets?

Answer 1

The built-in CalendarView widget does not provide the ability to change the color of the calendar cells in the month view mode. See source .

You can try the following approaches:

• Extend with CalendarView and implement onDraw yourself. You will have to override all existing drawing behavior, including these 4 methods:

    protected void onDraw (Canvas canvas) {
       drawBackground (canvas);
       drawWeekNumbersAndDates (canvas);
       drawWeekSeparators (canvas);
       drawSelectedDateVerticalBars (canvas);
   }
  

• Implement your own CalendarView, which allows you to customize cells. I propose this project as a good place to get started, as it already supports custom cells.

Last month, I was able to implement a small calendar view using Caldroid https://github.com/roomorama/Caldroid .

This is a flexible way to use, and it’s not as difficult to get a custom calendar view as the onDraw implementation from CalendarView .

Check the created view (just following the documentation):

And, of course, you can go further.

I wrote my own CalendarView just like the one that was seen on Google calendars. It allows you to scroll between months, listeners, add events, and is a gradle project: https://github.com/SundeepK/CompactCalendarView . It uses paint to complete the entire drawing, so it's easy to change it to do whatever you want.

The following project is the best alternative I've seen so far to allow the display of visual events associated with a specific event in a date cell in the calendar:
