添加权限

在config.json添加权限代码如下

 "reqPermissions": [      { "name": "ohos.permission.READ_CALENDAR"      },      { "name": "ohos.permission.WRITE_CALENDAR"      },      { "name": "ohos.permission.PUBLISH_AGENT_REMINDER"      }    ]

在java代码动态注册权限

public class MainAbility extends Ability {    @Override    public void onStart(Intent intent) { String[] permissions = {  "ohos.permission.READ_CALENDAR",  "ohos.permission.WRITE_CALENDAR",  "ohos.permission.PUBLISH_AGENT_REMINDER" }; requestPermissionsFromUser(permissions, 0); super.onStart(intent); super.setMainRoute(MainAbilitySlice.class.getName());    }}

添加日历事件

    public void insert(Context context) { try {     EventsHelper = CalendarDataHelper.creator(context, Events.class);     //新增日历事件     ValuesBucket valuesBucket = new ValuesBucket();     valuesBucket.putInteger(EventsColumns.ACC_ID, 1);     valuesBucket.putNull(EventsColumns.DURATION);     valuesBucket.putString(EventsColumns.START_TIMEZONE, TimeZone.getDefault().getID());     valuesBucket.putString(EventsColumns.EVENT_POSITION, "上海");     valuesBucket.putString(EventsColumns.TITLE, "标题");     valuesBucket.putString(EventsColumns.DESCRIPTION, "描述");     valuesBucket.putLong(EventsColumns.EVENT_START_TIME, System.currentTimeMillis());     valuesBucket.putLong(EventsColumns.EVENT_END_TIME, System.currentTimeMillis()+8*1000*60*60);  boolean isok=   EventsHelper.insert(valuesBucket);  System.err.println(isok?"####===>添加成功":"#####===>>添加失败"); } catch (DataAbilityRemoteException e) {     System.out.println(e.toString());     e.printStackTrace(); }    }

修改日历事件

  String PREDICTOR_TEMPLATE = "(%s)"; String sq1 = String.format(  Locale.ENGLISH,  PREDICTOR_TEMPLATE,  "calendar_id =" + 1); DataAbilityPredicates predicates = new DataAbilityPredicates(sq1); EventsHelper = CalendarDataHelper.creator(context, Events.class); //新增日历事件 ValuesBucket valuesBucket = new ValuesBucket(); valuesBucket.putInteger(EventsColumns.ACC_ID, 1); valuesBucket.putString(EventsColumns.TITLE, "修改标题"); //修改日历事件 boolean isupdate = EventsHelper.update(valuesBucket, predicates); if (isupdate) {     System.err.println("#######====>修改成功"); } else {     System.err.println("#######====>修改失败"); }

查询日历事件

  String PREDICTOR_TEMPLATE = "(%s)"; String sq1 = String.format(  Locale.ENGLISH,  PREDICTOR_TEMPLATE,  "calendar_id =" + 1); DataAbilityPredicates predicates = new DataAbilityPredicates(sq1); EventsHelper = CalendarDataHelper.creator(context, Events.class);//查询日历事件 String[] eventColumns = new String[]{  Events.ID,  EventsColumns.TITLE,  EventsColumns.DESCRIPTION,  EventsColumns.EVENT_START_TIME,  EventsColumns.EVENT_END_TIME, }; CalendarCollection calendarCollection = null; calendarCollection = EventsHelper.query(predicates, eventColumns);    int id=-1; while (calendarCollection != null && calendarCollection.hasNext()) {     Events resultEntity = (Events) calendarCollection.next()      .filter(entity -> entity instanceof Events)      .orElse(null);     System.err.println("####====>>"+resultEntity.getTitle() + "=" + resultEntity.getDescription()+"="+resultEntity.getId());  id=resultEntity.getId();//     Optional.ofNullable(calendarCollection).ifPresent(CalendarCollection::close);

删除日历事件

  EventsHelper = CalendarDataHelper.creator(ability, Events.class); DataAbilityPredicates predicates = new DataAbilityPredicates("title like '%修改标题%'"); int flag = EventsHelper.delete(predicates); System.err.println(flag > 0 ? "####===》删除成功" : "####===》删除失败");

添加日历提醒

 CalendarDataHelper      RemindersHelper = CalendarDataHelper.creator(context, Reminders.class); ValuesBucket reminderBucket = new ValuesBucket(); reminderBucket.putInteger(RemindersColumns.EVENT_ID, id); reminderBucket.putInteger(RemindersColumns.REMIND_TYPE, RemindersColumns.TYPE_ALARM); reminderBucket.putInteger(RemindersColumns.REMIND_MINUTES, 1); reminderBucket.putInteger("method",1); boolean   isok= false; try {     isok = RemindersHelper.insert(reminderBucket); } catch (DataAbilityRemoteException e) {     e.printStackTrace(); } System.err.println(isok?"###===>设置成功"+id:"#####====>>设置失败"+id);
