4: Using the calendar
Add appointment information. > To verify that an item supports a field, invoke
isSupportedField(int)
.
if (event.isSupportedField(Event.SUMMARY)) {
event.addString(Event.SUMMARY, Event.ATTR_NONE, "Meet with customer");
}
if (event.isSupportedField(Event.LOCATION)) {
event.addString(Event.LOCATION, Event.ATTR_NONE, "Conference Center");
}
Date start = new Date(System.currentTimeMillis() + 8640000);
if (event.isSupportedField(Event.START)) {
event.addDate(Event.START, Event.ATTR_NONE, start);
}
if (event.isSupportedField(Event.END)) {
event.addDate(Event.END, Event.ATTR_NONE, start + 72000000);
}
if (event.isSupportedField(Event.ALARM)) {
if (event.countValues(Event.ALARM) > 0) {
event.removeValue(Event.ALARM,0);
event.setInt(Event.ALARM, 0, Event.ATTR_NONE, 396000);
}
}
Create a recurring appointment. 1. Create a
RepeatRule
object. The
RepeatRule
class defines fields for the properties and values
that you can set, such as COUNT, FREQUENCY, and INTERVAL.
2. To retrieve an array of supported fields, invoke
RepeatRule.getFields()
.
3. To define a recurring pattern, invoke
setInt(int, int)
or
setDate(int, int, int,
long)
on a new
RepeatRule
object.
RepeatRule recurring = new RepeatRule();
recurring.setInt(RepeatRule.FREQUENCY, RepeatRule.MONTHLY);
recurring.setInt(RepeatRule.DAY_IN_MONTH, 14);
4. To assign a recurrence pattern to an appointment, invoke
setRepeat(RepeatRule)
on an
event.
EventList eventList = (EventList)PIM.getInstance().openPIMList(
PIM.EVENT_LIST, PIM.READ_WRITE);
Event event = eventList.createEvent();
event.setRepeat(recurring);
Change appointment information. 1. To replace an existing value with a new one, invoke the appropriate set method, such as
setString()
.
2. To determine if a value is already set for the field, invoke
countValues().
3. To change an existing value, use the corresponding set method, such as s
etString()
.
if (event.countValues(Event.LOCATION) > 0) {
event.setString(Event.LOCATION, 0, Event.ATTR_NONE, "Board Room");
}
