如何在Android中以编程方式在日历中创建提醒(而不是事件)？

import android.content.ContentResolver;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.provider.CalendarContract;

public class CalendarReminderHelper {

    public static void createReminder(Context context, String title, long startTimeMillis, long endTimeMillis, long reminderTimeMillis) {
        ContentResolver cr = context.getContentResolver();

        // 查询可用的日历账户
        Cursor cursor = cr.query(CalendarContract.Calendars.CONTENT_URI, null, null, null, null);
        if (cursor.moveToFirst()) {
            // 获取第一个日历账户
            String calendarId = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars._ID));

            // 创建日历事件
            ContentValues eventValues = new ContentValues();
            eventValues.put(CalendarContract.Events.CALENDAR_ID, calendarId);
            eventValues.put(CalendarContract.Events.TITLE, title);
            eventValues.put(CalendarContract.Events.DTSTART, startTimeMillis);
            eventValues.put(CalendarContract.Events.DTEND, endTimeMillis);
            eventValues.put(CalendarContract.Events.EVENT_TIMEZONE, "Asia/Shanghai");
            Uri eventUri = cr.insert(CalendarContract.Events.CONTENT_URI, eventValues);

            // 创建提醒事件
            ContentValues reminderValues = new ContentValues();
            reminderValues.put(CalendarContract.Reminders.EVENT_ID, Long.parseLong(eventUri.getLastPathSegment()));
            reminderValues.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
            reminderValues.put(CalendarContract.Reminders.MINUTES, reminderTimeMillis / (60 * 1000));
            cr.insert(CalendarContract.Reminders.CONTENT_URI, reminderValues);
        }
        cursor.close();
    }
}
