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, model.getContent());//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, model.getTime());//开始时间        event.put(Events.DTEND, model.getTime());//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, TimeZone.getDefault().getID());//时区，必须有        Uri newEvent = App.sContext.getContentResolver().insert(eventsUri, event);        // 事件提醒的设定        long id = Long.parseLong(newEvent != null ? newEvent.getLastPathSegment() : "1");        ContentValues values = new ContentValues();        values.put(Reminders.EVENT_ID, id);        values.put(Reminders.MINUTES, "10");//提前提醒时间 min        values.put(Reminders.METHOD, Reminders.METHOD_ALERT);//提醒方式        App.sContext.getContentResolver().insert(remindersUri, values);    }    /**     * 根据账户查询账户日历     *     * @return List     */    public static List<EventModel> queryEvents() {        List<EventModel> calendars = new ArrayList<>();        Cursor cursor;        // 本地帐户查询：ACCOUNT_TYPE_LOCAL是一个特殊的日历账号类型，它不跟设备账号关联。这种类型的日历不同步到服务器        // 如果是谷歌的账户是可以同步到服务器的        cursor = App.sContext.getContentResolver().query(eventsUri, EVENTS_COLUMNS,                Calendars.ACCOUNT_NAME + " = ?

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()

PS:其实可以设置的参数非常的多，我暂时只是用涉及到了提示时间和提示内容，还有的操作需要小伙伴们自己发掘了，因为能搜到的栗子确实不多，我把一个比较有参考意义的类也上传了GitHub，在help包下，希望会对小伙伴有所帮助。

虽然不知道是谁写的，但挺有参考意义的。 https://github.com/wdzawdh/EventLog/blob/master/app/src/main/java/help/CalendarsResolver.java
