我们如何在Android日历中添加提醒数据？

这是我用于 ICS 的一个类

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);
        }


}

}

如果您的应用程序面向 Android 6.0 及更高版本，则下面的类包含用于在运行时请求读/写日历权限的辅助函数。
