鸿蒙 next 写入考试时间日程到系统日历
1.获取权限
在entry/src/main/module.json5
中新增两条申请的权限, $string:calendar_reason
是在目录entry/src/main/resources/string.json
中配置。
{
"module": {
"requestPermissions": [
{
"name" : "ohos.permission.READ_CALENDAR",
"reason": "$string:calendar_reason",
"usedScene": {
"abilities": [
"EntryAbility"
],
"when":"inuse"
}
},
{
"name": "ohos.permission.WRITE_CALENDAR",
"reason": "$string:calendar_reason",
"usedScene": {
"abilities": [
"EntryAbility"
],
"when": "inuse"
}
},
]
}
}
2.封装CalendarUtil工具类来使用日历
import { calendarManager } from '@kit.CalendarKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { common, PermissionRequestResult, Permissions, abilityAccessCtrl } from '@kit.AbilityKit';
import Config from '../../http/Config';
import UserCacheManager from './UserCacheManager';
import { JSON } from '@kit.ArkTS';
export class CalendarUtil {
private static calendarMgr: calendarManager.CalendarManager | null = null;
static requestPermissions(context: Context) {
// 注册日历权限, 来自: https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-calendarmanager-V5
const permissions: Permissions[] = ['ohos.permission.READ_CALENDAR', 'ohos.permission.WRITE_CALENDAR'];
let atManager = abilityAccessCtrl.createAtManager();
return atManager.requestPermissionsFromUser(context, permissions).then((result: PermissionRequestResult) => {
console.log(`get Permission success, result: ${JSON.stringify(result)}`);
CalendarUtil.calendarMgr = calendarManager.getCalendarManager(context);
}).catch((error: BusinessError) => {
console.error(`get Permission error, error. Code: ${error.code}, message: ${error.message}`);
})
}
private static getExamDateTitle() {
return UserCacheManager.getSubjectCatName() + '考试';
}
private static getExamDateEvent(examDate: string) {
const date = new Date(examDate);
const curTime = date.getTime();
const event: calendarManager.Event = {
type: calendarManager.EventType.NORMAL,
title: CalendarUtil.getExamDateTitle(),
description: `由${Config.app_name}应用创建日程`,
startTime: curTime,
endTime: curTime + 24 * 60 * 60 * 1000,
isAllDay: true,
reminderTime: [12 * 60]
};
console.log('run getExamDateEvent', JSON.stringify(event))
return event;
}
// 创建考试日程
private static addExamDateEvent(calendar: calendarManager.Calendar, examDate: string) {
const event = CalendarUtil.getExamDateEvent(examDate);
calendar.addEvent(event).then((data: number) => {
console.info(`Succeeded in adding event, id -> ${data}`);
}).catch((err: BusinessError) => {
console.error(`Failed to addEvent. Code: ${err.code}, message: ${err.message}`);
});
}
// 更新考试日程
private static updateExamDateEvent(calendar: calendarManager.Calendar, examDate: string, eventId?: number) {
const oriEvent = CalendarUtil.getExamDateEvent(examDate);
oriEvent.id = eventId;
calendar.updateEvent(oriEvent).then(() => {
console.info(`Succeeded in updating event`);
}).catch((err: BusinessError) => {
console.error(`Failed to update event. Code: ${err.code}, message: ${err.message}`);
});
}
// 查询考试日程
private static getExamDateEvents(calendar: calendarManager.Calendar) {
const filter = calendarManager.EventFilter.filterByTitle(CalendarUtil.getExamDateTitle());
return calendar.getEvents(filter)
}
// 添加考试时间为日历日程
static addExamDateCalendar(examDate: string) {
CalendarUtil.calendarMgr?.getCalendar().then((calendar: calendarManager.Calendar) => {
console.info(`Succeeded in getting calendar -> ${JSON.stringify(calendar)}`);
CalendarUtil.getExamDateEvents(calendar).then((data: calendarManager.Event[]) => {
if (data && data.length > 0) {
// 已经存在该日程则更新
console.log('run getEvents', JSON.stringify(data))
CalendarUtil.updateExamDateEvent(calendar, examDate, data[0].id)
} else {
// 没有日程则添加
CalendarUtil.addExamDateEvent(calendar, examDate)
}
});
}).catch((err: BusinessError) => {
console.error(`Failed to get calendar. Code: ${err.code}, message: ${err.message}`);
});
}
}
3.在需要写入日历的代码位置使用一下代码
CalendarUtil.requestPermissions(AppUtil.getContext()).then(() => {
CalendarUtil.addExamDateCalendar(this.examDate);
})
