Android日历事件提醒

最近遇到一个需求，是要在特定的时间提示特定的用户干特定的是，比如你该吃早饭了呀、你该上厕所了呀、你该找女朋友了呀，我去，反正就是这么个需求。我想和推送差不多，不过推送什么的也不能百分百的推到，要对特定的用户提示特定的消息也很麻烦。于是乎就产生了通过系统日历来提示用户的方案。还是希望能帮到其他有类似需求的小伙伴，要是真帮到了希望能点个赞。

每天都要过得开心 ( ゜- ゜)つロ乾杯！

关键代码

其实说白了就是通过ContentResolver给日历相关的数据库insert数据，那么系统就会根据你的要求来提示用户，就是这么简单。

public class CalendarEvent {private static final String ACCOUNT_NAME = Constants.ACCOUNT_NAME;/*** 使用以下Uri时，Android版本>=14; 注意引用包路径：android.provider.CalendarContract下的；**/private static Uri calendarsUri = Calendars.CONTENT_URI;private static Uri eventsUri = Events.CONTENT_URI;private static Uri remindersUri = Reminders.CONTENT_URI;/*** Events table columns*/public static final String[] EVENTS_COLUMNS = new String[]{Events._ID,Events.CALENDAR_ID, Events.TITLE, Events.DESCRIPTION,Events.EVENT_LOCATION, Events.DTSTART, Events.DTEND,Events.EVENT_TIMEZONE, Events.HAS_ALARM, Events.ALL_DAY,Events.AVAILABILITY, Events.ACCESS_LEVEL, Events.STATUS,};/*** 插入事件*/public static void insertEvent(EventModel model) {String calId = queryCalId();if (TextUtils.isEmpty(calId)) {addAccount();insertEvent(model);return;}// 插入事件ContentValues event = new ContentValues();event.put(Events.TITLE, ACCOUNT_NAME);//标题event.put(Events.DESCRIPTION, Content());//备注event.put(Events.EVENT_LOCATION, "");//地点用需要可以添加)event.put(Events.CALENDAR_ID, calId);event.put(Events.DTSTART, Time());//开始时间event.put(Events.DTEND, Time());//结束时间event.put(Events.STATUS, Events.STATUS_CONFIRMED);event.put(Events.HAS_ATTENDEE_DATA, 1);event.put(Events.HAS_ALARM, 1);//是否生效?event.put(Events.EVENT_TIMEZONE, Default().getID());//时区，必须有Uri newEvent = ContentResolver().insert(eventsUri, event);// 事件提醒的设定long id = Long.parseLong(newEvent != null ?

", new String[]{ACCOUNT_NAME}, null);while (cursor != null && veToNext()) {EventModel eventModel = new EventModel();eventModel.String(0));eventModel.String(5));eventModel.String(3));calendars.add(eventModel);}return calendars;}/*** 更新某条Event** @param model model*/public static void updateEvent(EventModel model) {ContentValues contentValues = new ContentValues();contentValues.put(Events.DTSTART, Time());contentValues.put(Events.DESCRIPTION, Content());ContentResolver().update(eventsUri, contentValues, Events._ID + " =?

", new String[]{id});}/*** 删除所有Event** @return The number of rows deleted.*/public static int deleteAllEvent() {return ContentResolver().delete(eventsUri, Events.CALENDAR_ID + " =? ", new String[]{queryCalId()});}/*** 查询 calendar_id** @return calId*/private static String queryCalId() {Cursor userCursor = null;try {userCursor = ContentResolver().query(calendarsUri, null,"name=?", new String[]{ACCOUNT_NAME}, null);} catch (Exception e) {e.printStackTrace();}if (userCursor == null) {return null;}if (Count() > 0) {veToLast(); //是向符合条件的最后一个账户添加ColumnIndex("_id"));}return "";}/*** 添加账户*/private static void addAccount() {ContentValues value = new ContentValues();value.put(Calendars.ACCOUNT_NAME, ACCOUNT_NAME);value.put(Calendars.ACCOUNT_TYPE, "LOCAL");value.put(Calendars._SYNC_ID, "1");value.put(Calendars.DIRTY, "1");value.put(Calendars.NAME, ACCOUNT_NAME);value.put(Calendars.CALENDAR_DISPLAY_NAME, ACCOUNT_NAME);value.put(Calendars.CALENDAR_COLOR, Color.BLUE);value.put(Calendars.CALENDAR_ACCESS_LEVEL, Calendars.CAL_ACCESS_OWNER);value.put(Calendars.CALENDAR_TIME_ZONE, Default().getID());value.put(Calendars.VISIBLE, "1");value.put(Calendars.SYNC_EVENTS, "1");value.put(Calendars.OWNER_ACCOUNT, ACCOUNT_NAME);value.put(Calendars.CAN_ORGANIZER_RESPOND, "1");Uri calendarUri = Calendars.CONTENT_URI;calendarUri = calendarUri.buildUpon().appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true").appendQueryParameter(Calendars.ACCOUNT_NAME, ACCOUNT_NAME).appendQueryParameter(Calendars.ACCOUNT_TYPE, "1").build();ContentResolver().insert(calendarUri, value);}}

使用方式（增删改查）

public class EventModel {private String id;private String time;private String content;...
}CalendarEvent.insertEvent(eventModel);
CalendarEvent.deleteEvent(id);
CalendarEvent.deleteAllEvent();
CalendarEvent.updateEvent(eventModel);
CalendarEvent.queryEvents()
