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);
