ExtendedCalendarView

====================

![image](https://github.com/tyczj/ExtendedCalendarView/raw/master/ExtendedCalendarView.png)

This project is meant for people who want to display a calendar view and show that there are events on certain days.

What I did was pull out the calendar view from Google's Calendar application found here. It is still a work in progress but the project should run. The example project pulls events from the google calendar provider and inserts them into the examples database

https://github.com/android/platform_packages_apps_calendar.

Implementation is not the easiest though as there is a lot to it but I hope to filter out stuff that is not needed to try to make it simpler

A quick run though of how to use it:

in your activity before you set the content view you need to create a Calendar Controller

    public class MainActivity extends Activity implements EventHandler{

    

	private CalendarController mController;

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		mController = CalendarController.getInstance(this);

		setContentView(R.layout.cal_layout);

        mController.registerEventHandler(R.id.cal_frame, (EventHandler) monthFrag);

        

        mController.registerFirstEventHandler(0, this);

	}

	

The put in the MonthByWeekFragment to your view

    FragmentTransaction ft = getFragmentManager().beginTransaction();

				

	monthFrag = new MonthByWeekFragment(System.currentTimeMillis(), false);

        ft.replace(R.id.cal_frame, monthFrag).commit();

        

You also need to override handleEvent, this gets called when you click on a day on the calendar and gets called when you click on an event in the day view

    @Override

	public void handleEvent(EventInfo event) {

		if (event.eventType == EventType.GO_TO) {

		// day selected on calendsr, start DayFragment to display the day that was clicked

			this.event = event;

			dayView = true;

				FragmentTransaction ft = getFragmentManager().beginTransaction();

				dayFrag = new DayFragment(event.startTime.toMillis(true),1);

				ft.replace(R.id.cal_frame, dayFrag).addToBackStack(null).commit();

		}if(event.eventType == EventType.VIEW_EVENT){

			//TODO do something when an event is clicked	

		}

		

	}

	

	

Calendar Content Provider

=========================

To display events on the calendar I have build a content provider that the calendar uses which replicates how it is done in googles calendar app.

things that it needs is the start and end date in a milliseconds timestamp.

those should go in the START and END columns of the database

    values.put(CalendarProvider.END, endTimestamp));

    values.put(CalendarProvider.START, startTimestamp);

    

You also need to get the julian start/end day from the timestamp like so

    int startDay = Time.getJulianDay(startTimestamp, TimeUnit.MILLISECONDS.toSeconds(tz.getOffset(startTimestamp)));

    int endDay = Time.getJulianDay(endTimestamp, TimeUnit.MILLISECONDS.toSeconds(tz.getOffset(endTimestamp)));

    

the put them in the start day and end day columns of the database

    values.put(CalendarProvider.START_DAY, startDay);

    values.put(CalendarProvider.END_DAY, endDay);

    

The last thing you need in the database is the start/end time in minutes and put them in the start time and end time columns

    values.put(CalendarProvider.START_TIME, startMin);

    values.put(CalendarProvider.END_TIME, endMin);
