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
}
}
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);
