Here is a class I used for ICS
这是我用于 ICS 的类
import android.app.Activity;
import android.content.ContentResolver;
import android.content.ContentUris;
import android.content.ContentValues;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.CalendarContract;
import android.provider.CalendarContract.Calendars;
import android.provider.CalendarContract.Events;
import android.provider.CalendarContract.Reminders;
import android.util.Log;
public class IcsCalendarHelper {
//Remember to initialize this activityObj first, by calling initActivityObj(this) from
//your activity
private static final String DEBUG_TAG = "CalendarActivity";
private static Activity activityObj;
public static void initActivityObj(Activity obj)
{
activityObj = obj;
}
public static void IcsMakeNewCalendarEntry(String title,String description,String location,long startTime,long endTime, int allDay,int hasAlarm, int calendarId,int selectedReminderValue) {
ContentResolver cr = activityObj.getContentResolver();
ContentValues values = new ContentValues();
values.put(Events.DTSTART, startTime);
values.put(Events.DTEND, endTime);
values.put(Events.TITLE, title);
values.put(Events.DESCRIPTION, description);
values.put(Events.CALENDAR_ID, calendarId);
if (allDay == 1)
{
values.put(Events.ALL_DAY, true);
}
if (hasAlarm==1)
{
values.put(Events.HAS_ALARM, true);
}
//Get current timezone
values.put(Events.EVENT_TIMEZONE,TimeZone.getDefault().getID());
Log.i(DEBUG_TAG, "Timezone retrieved=>"+TimeZone.getDefault().getID());
Uri uri = cr.insert(Events.CONTENT_URI, values);
Log.i(DEBUG_TAG, "Uri returned=>"+uri.toString());
// get the event ID that is the last element in the Uri
long eventID = Long.parseLong(uri.getLastPathSegment());
if (hasAlarm==1)
{
ContentValues reminders = new ContentValues();
reminders.put(Reminders.EVENT_ID, eventID);
reminders.put(Reminders.METHOD, Reminders.METHOD_ALERT);
reminders.put(Reminders.MINUTES, selectedReminderValue);
Uri uri2 = cr.insert(Reminders.CONTENT_URI, reminders);
}
}
}
If your app is targeting Android 6.0 and above, the class below contains helper functions to request for READ/WRITE calendar permissions during runtime.
如果您的应用面向 Android 6.0 及更高版本，则下面的类包含在运行时请求 READ/WRITE 日历权限的辅助函数。

Hi use the following code to add the event programmatically to the calendar.
您好，使用以下代码以编程方式将事件添加到日历中。
Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
ContentResolver cr = getContentResolver();
ContentValues values = new ContentValues();
values.put("calendar_id", id);
values.put("title", tasktitle);
values.put("allDay", 0);
values.put("dtstart", settime);
values.put("dtend", cal.getTimeInMillis()+60*60*1000);
values.put("description", description);
values.put("visibility", 0);
values.put("transparency", 0);
values.put("hasAttendeeData", 1);
values.put("hasAlarm", 0);
event = cr.insert(EVENT_URI, values);
event1=event;
dat1 = event.toString();
long id=-1;
if (event != null)
{
id = Long.parseLong(event.getLastPathSegment());
ContentValues values1 = new ContentValues();
values1.put("event_id", id);
values1.put("method", 1); //METHOD_ALERT
Uri reminder = Uri.parse(getCalendarUriBase(this) + "reminders");
this.getContentResolver().insert(reminder, values1);
ContentValues attendees = new ContentValues();
attendees.put("event_id", id);
attendees.put("attendeeEmail", partmail1);
attendees.put("attendeeRelationship", 2);//RELATIONSHIP_ATTENDEE
attendees.put("attendeeStatus", 3); //ATTENDEE_STATUS_INVITED
attendees.put("attendeeType", 1); //TYPE_REQUIRED
id1=(int)id;
alarmid = (int) id;
Uri attendeesUri = null;
if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
{
attendeesUri = Uri.parse("content://com.android.calendar/attendees");
}
else if(Integer.parseInt(Build.VERSION.SDK) < 8)
{
attendeesUri = Uri.parse("content://calendar/attendees");
}
this.getContentResolver().insert(attendeesUri, attendees);
Toast.makeText(this, "Task Scheduled Successfully", Toast.LENGTH_SHORT).show();
}
// reminder insert
Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
values = new ContentValues();
values.put( "event_id", id);
values.put( "method", 1 );
values.put( "minutes", 0 );
cr.insert( REMINDERS_URI, values );

Check How to add calendar events in Android?with the solution by oriharel. It's in fact very good because it asks the user in which calendar to put the event.
