Android日历提醒是非常好的提醒功能,笔者在做的过程中,遇到的一些问题,现整理出来,以供参考。
- <uses-permission android:name="android.permission.WRITE_CALENDAR" />
- <uses-permission android:name="android.permission.READ_CALENDAR" />
如果需要读取日历数据,需要加入READ_CALENDAR权限。若需要对日历数据进行删改操作,需要WRITE_CALENDAR权限。
CalendarContract.Events表包含事件的信息,比如标题、描述、开始时间等,如需查看所支持字段的完整列表,请参阅 CalendarContract.Events。
常量 | 描述 |
---|---|
_ID | 事件ID,非常重要,更新删除数据都要用到。 |
CALENDAR_ID | 事件所属日历用户ID。 |
TITLE | 事件的名称。 |
DESCRIPTION | 事件的描述。 |
DTSTART | 事件开始时间,以从公元纪年开始计算的协调世界时毫秒数表示。 |
DTEND | 事件结束时间,以从公元纪年开始计算的协调世界时毫秒数表示。 |
EVENT_TIMEZONE | 事件的时区。 |
EVENT_END_TIMEZONE | 事件结束时间的时区。 |
DURATION | RFC5545 格式的事件持续时间。例如,值为 "PT1H" 表示事件应持续一小时,值为 "P2W" 表示持续 2 周。 |
ALL_DAY | 值为 1 表示此事件占用一整天(按照本地时区的定义)。值为 0 表示它是常规事件,可在一天内的任何时间开始和结束。 |
RRULE | 事件的重复发生规则格式。例如,"FREQ=WEEKLY;COUNT=10;WKST=SU" 。您可以在此处找到更多示例。 |
RDATE | 事件的重复发生日期。RDATE 与 RRULE 通常联合用于定义一组存在聚合关系的重复实例。如需查看更详细的介绍,请参阅 RFC5545 规范。 |
AVAILABILITY | 将此事件视为忙碌时间还是可调度的空闲时间。 |
HAS_ALARM | 设置是否有闹钟提醒,0-没有,1-有 |
增加事件需要用户信息(CalendarContract.Events.CALENDAR_ID),相关代码如下:
- private static final String CALENDER_URL = "content://com.android.calendar/calendars";
-
- private static final String CALENDARS_NAME = "XX";// 随便写
- private static final String CALENDARS_ACCOUNT_NAME = "XX";// 随便写
- private static final String CALENDARS_ACCOUNT_TYPE = CalendarContract.ACCOUNT_TYPE_LOCAL;
- private static final String CALENDARS_DISPLAY_NAME = StringUtils.getString(R.string.app_name) + "账户";// 随便写
-
- /**
- * 检查是否已经添加了日历账户,如果没有添加先添加一个日历账户再查询
- * @return 获取账户成功返回账户id,否则返回-1
- */
- private static int checkAndAddCalendarAccount(Context context) {
- int oldId = checkCalendarAccount(context);
- if (oldId >= 0) {
- return oldId;
- } else {
- long addId = addCalendarAccount(context);
- if (addId >= 0) {
- return checkCalendarAccount(context);
- } else {
- return -1;
- }
- }
- }
-
- /**
- * @return 检查是否存在现有账户,存在则返回账户id,否则返回-1
- */
- private static int checkCalendarAccount(Context context) {
- Cursor userCursor = context.getContentResolver().query(Uri.parse(CALENDER_URL), null, null, null, null);
- try {
- if (userCursor == null) { //查询返回空值
- return -1;
- }
- int columnIndex = userCursor.getColumnIndex(CalendarContract.Calendars._ID);
- int count = userCursor.getCount();
- if (count > 0) { //存在现有账户,取第一个账户的id返回
- userCursor.moveToFirst();
- return userCursor.getInt(columnIndex);
- } else {
- return -1;
- }
- } catch (Exception ex) {
- // do nothing
- return -1;
- } finally {
- if (userCursor != null) {
- userCursor.close();
- }
- }
- }
-
- /**
- * @return 添加日历账户,账户创建成功则返回账户id,否则返回-1
- */
- private static long addCalendarAccount(Context context) {
- TimeZone timeZone = TimeZone.getDefault();
- ContentValues value = new ContentValues();
- value.put(CalendarContract.Calendars.NAME, CALENDARS_NAME);
- value.put(CalendarContract.Calendars.ACCOUNT_NAME, CALENDARS_ACCOUNT_NAME);
- value.put(CalendarContract.Calendars.ACCOUNT_TYPE, CALENDARS_ACCOUNT_TYPE);
- value.put(CalendarContract.Calendars.CALENDAR_DISPLAY_NAME, CALENDARS_DISPLAY_NAME);
- value.put(CalendarContract.Calendars.VISIBLE, 1);
- value.put(CalendarContract.Calendars.CALENDAR_COLOR, Color.BLUE);
- value.put(CalendarContract.Calendars.CALENDAR_ACCESS_LEVEL, CalendarContract.Calendars.CAL_ACCESS_OWNER);
- value.put(CalendarContract.Calendars.SYNC_EVENTS, 1);
- value.put(CalendarContract.Calendars.CALENDAR_TIME_ZONE, timeZone.getID());
- value.put(CalendarContract.Calendars.OWNER_ACCOUNT, CALENDARS_ACCOUNT_NAME);
- value.put(CalendarContract.Calendars.CAN_ORGANIZER_RESPOND, 0);
-
- Uri calendarUri = Uri.parse(CALENDER_URL);
- calendarUri = calendarUri.buildUpon()
- .appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true")
- .appendQueryParameter(CalendarContract.Calendars.ACCOUNT_NAME, CALENDARS_ACCOUNT_NAME)
- .appendQueryParameter(CalendarContract.Calendars.ACCOUNT_TYPE, CALENDARS_ACCOUNT_TYPE)
- .build();
-
- Uri result = context.getContentResolver().insert(calendarUri, value);
- return result == null ? -1 : ContentUris.parseId(result);
- }
-
先创建日历事件,再将事件加入日历提醒,代码如下:
- private static final String CALENDER_EVENT_URL = "content://com.android.calendar/events";
- private static final String CALENDER_REMINDER_URL = "content://com.android.calendar/reminders";
- private static final String[] PERMISSION_LIST = {Manifest.permission.READ_CALENDAR, Manifest.permission.WRITE_CALENDAR};
-
-
- /**
- * 真正添加日历事件
- *
- * @param context:上下文
- * @param map:日历事件的信息
- * @return 返回事件id
- */
- private static long addCalendarEvent(Context context, @NonNull Map
map) { - if (context == null) {
- return 0;
- }
- if (!XXPermissions.isGranted(context, PERMISSION_LIST)) {
- return 0;
- }
- int calId = checkAndAddCalendarAccount(context); //获取日历账户的id
- if (calId < 0) { //获取账户id失败直接返回,添加日历事件失败
- return 0;
- }
-
- String title = (String) map.get("title");
- String description = (String) map.get("description");
- long start = 0;
- Object originStartTime = map.get("start_time");
- if (originStartTime instanceof Long) {
- start = (Long) originStartTime;
- }
- String rule = (String) map.get("rule");
-
- ContentValues event = new ContentValues();
- event.put(CalendarContract.Events.TITLE, title);
- event.put(CalendarContract.Events.DESCRIPTION, description);
- event.put(CalendarContract.Events.CALENDAR_ID, calId); //插入账户的id
- event.put(CalendarContract.Events.DTSTART, start);
- //event.put(CalendarContract.Events.DTEND, end);// 与DURATION不能同时设置
- event.put(CalendarContract.Events.HAS_ALARM, 1);//设置有闹钟提醒
- event.put(CalendarContract.Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());//这个是时区,必须有
- event.put(CalendarContract.Events.DURATION, "P0S");// 重复设置必须设置,否则日期有问题
- if (!StringUtils.isEmpty(rule)) {
- event.put(CalendarContract.Events.RRULE, rule);// 重复规则 rrule(Recurrence Rule)
- }
- Uri newEvent = context.getContentResolver().insert(Uri.parse(CALENDER_EVENT_URL), event); //添加事件
- if (newEvent == null) { //添加日历事件失败直接返回
- LogUtils.d("addCalendarEvent2 newEvent 添加日历事件失败直接返回");
- return 0;
- }
- //事件提醒的设定
- ContentValues values = new ContentValues();
- values.put(CalendarContract.Reminders.EVENT_ID, ContentUris.parseId(newEvent));
- values.put(CalendarContract.Reminders.MINUTES, 0);// 提前0分钟提醒
- values.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
- Uri reminderEvent = context.getContentResolver().insert(Uri.parse(CALENDER_REMINDER_URL), values);
- if (reminderEvent == null) {
- LogUtils.d("addCalendarEvent2 reminderEvent 添加日历事件失败直接返回");
- }
- return Long.parseLong(newEvent.getLastPathSegment());
- }
总结下增加事件的规则:
碎碎念:
1、之前添加重复事件,只设置 DTEND ,导致添加的天数有问题,改成DURATION就好了。
2、_ID(事件ID)非常重要,增加日历提醒后需要保存起来,后续的删改查都需要这个信息。
查找比较简单了,这里使用事件ID(_ID),代码如下:
- /**
- * 检查日历事件
- *
- * @param context:
- * @param eventId:
- * @return 返回事件是否存在。true-事件存在,false-事件不存在
- */
- public static boolean checkCalendarEvent(Context context, long eventId) {
- if (context == null || eventId <= 0) {
- return false;
- }
- if (!XXPermissions.isGranted(context, PERMISSION_LIST)) {
- return false;
- }
- Uri uri = ContentUris.withAppendedId(Uri.parse(CALENDER_EVENT_URL), eventId);
- Cursor eventCursor = context.getContentResolver().query(uri, null, null, null, null);
- if (eventCursor == null) {
- return false;
- }
- boolean result = eventCursor.getCount() > 0;
- eventCursor.close();
- return result;
- }
- public static void updateCalendarEvent(Context context, long eventId) {
- if (context == null || eventId <= 0) {

- }

- }
