学习打卡
1、手机定位
在module.json5文件里面配置位置权限
代码向用户申请权限（弹窗）
/*** 动态授权*/
async aboutToAppear() {// 使用UIExtensionAbility：将common.UIAbilityContext 替换为common.UIExtensionContextconst context: common.UIAbilityContext = getContext(this) as common.UIAbilityContext;// 定义要申请的权限const permissions: Array<Permissions> = ['ohos.permission.APPROXIMATELY_LOCATION'];let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();// requestPermissionsFromUser会判断权限的授权状态来决定是否唤起弹窗try {const data = await atManager.requestPermissionsFromUser(context, permissions);let grantStatus: Array<number> = data.authResults;let length: number = grantStatus.length;for (let i = 0; i < length; i++) {if (grantStatus[i] === 0) {// 获取位置信息this.getLocation()} else {// 用户拒绝授权，提示用户必须授权才能访问当前页面的功能，并引导用户到系统设置中打开相应的权限showToast('用户必须授权才能访问当前定位功能')return;}}} catch (error) {showToast('用户必须授权才能访问当前定位功能')}
}获取用户位置信息，获取经度纬度然后进行地理编码
/*** 获取位置*/
async getLocation() {let request: geoLocationManager.SingleLocationRequest = {'locatingPriority': geoLocationManager.LocatingPriority.PRIORITY_LOCATING_SPEED,'locatingTimeoutMs': 10000}try {// 调用getCurrentLocation获取当前设备位置，通过promise接收上报的位置const result = await geoLocationManager.getCurrentLocation(request)Logger.info('current location: ' + JSON.stringify(result));// 判断地理编码服务是否可用let isAvailable = geoLocationManager.isGeocoderAvailable();if (isAvailable) {// 地理编码服务可用let reverseGeocodeRequest: geoLocationManager.ReverseGeoCodeRequest ={ "latitude": result.latitude, "longitude": result.longitude, "maxItems": 1 };geoLocationManager.getAddressesFromLocation(reverseGeocodeRequest, (err, data) => {if (err) {Logger.error('getAddressesFromLocation err: ' + JSON.stringify(err));} else {Logger.info('getAddressesFromLocation data: ' + JSON.stringify(data));// 成功获取到位置信息this.location = data[0].administrativeArea + '' + data[0].subAdministrativeAreareturn}});} else {showToast('地理编码服务不可用')}} catch (err) {Logger.error("errCode:" + JSON.stringify(err));showToast("获取位置失败")}
}2、日历组件
使用我们一开始项目准备阶段引入的鸿蒙三方库ibest-ui
import { IBestCalendar } from "@ibestservices/ibest-ui";// 日历
IBestCalendar({clock: true, // 设置 clock 为 true, 可开启打卡模式, 打卡模式下只能切换年月, 不能选择日期defaultSelectedDate: this.clockDate, // 打卡的日期是一个字符串数组clockSuccessText: '✔', // 已打卡展示的unClockText: '✖', // 未打卡展示的
})3、打卡记录
4、编写学习打卡接口方法
import http from '../request/Request'
import { LearnClockParam, PageParam, UserLearnClockData } from './LearnClockApi.type'
import { PageVo } from './MessageApi.type'/*** 消息接口*/
class LearnClockApi {/*** 学习打卡*/learnClock = (data: LearnClockParam) => {return http.post('/v1/learn/clock', data)}/*** 查询用户已打卡的日期*/listClockTime = (): Promise<Array<string>> => {return http.get('/v1/learn/listClockTime')}/*** 查询用户今日是否打卡*/isClock = (): Promise<boolean> => {return http.get('/v1/learn/isClock')}/*** 分页查询用户打卡记录*/pageListUserClock = (data: PageParam): Promise<PageVo<UserLearnClockData>> => {return http.get('/v1/learn/page?page=' + data.page + '&&pageSize=' + data.pageSize)}
}const learnClockApi = new LearnClockApi();export default learnClockApi as LearnClockApi;/*** 学习打卡入参*/
export interface LearnClockParam {/*** 打卡地点*/location: string/*** 打卡内容*/content: string
}/*** 时间*/
export interface BaseTime {/*** 创建时间*/createTime?: Date/*** 更新时间*/updateTime?: Date
}/*** 分页参数*/
export interface PageParam {/*** 当前页*/page?: number/*** 每一页展示的数据条数*/pageSize?: number
}/*** 分页响应参数*/
export interface PageVo<T> {current: number,size: number,total: number,records: Array<T>
}/*** 用户打卡记录数据*/
export interface UserLearnClockData extends BaseTime {/*** 学习打卡id*/id: number/*** 打卡地点*/location: string/*** 打卡内容*/content: string/*** 用户昵称*/nickname: string/*** 创建时间字符串格式*/time: string}学习目标
1、目标整体进度
使用的是鸿蒙进度条组件
// 环形进度条
Stack() {Progress({value: this.countData.completeQuantity,total: this.countData.totalQuantity,type: ProgressType.Ring}).width($r('app.float.common_width_medium')).height($r('app.float.common_height_medium')).color('#1698CE').style({ strokeWidth: 8 })Text(this.countData.completeQuantity + '/' + this.countData.totalQuantity).fontSize($r('app.float.common_font_size_tiny'))
}2、添加目标
使用的是ibest-ui里面的IBestDialog组件
IBestDialog({visible: $dialogVisible,title: "添加目标",showCancelButton: true,defaultBuilder: (): void => this.formInputContain(),beforeClose: async (action) => {if (action === 'cancel') {return true}const valueLength = this.inputTargetValue.trim().length;this.formInputError = !valueLength;if (!this.formInputError) {// 添加新目标await targetInfoApi.addTargetInfo({ content: this.inputTargetValue })showToast('添加目标成功')// 查询数据this.page = 1this.aboutToAppear()return true}return !this.formInputError}
})@BuilderformInputContain() {Column() {TextInput({ 'placeholder': '请输入目标内容,长度不能超过255字符' }).fontSize(14).placeholderFont({ size: 14 }).onChange((value) => {this.inputTargetValue = value;this.formInputError = false})if (this.formInputError) {Text('目标内容不能为空').width(CommonConstant.WIDTH_FULL).textAlign(TextAlign.Start).margin({top: 5,left: 5}).fontColor(Color.Red).fontSize($r('app.float.common_font_size_small')).transition({ type: TransitionType.Insert, opacity: 1 }).transition({ type: TransitionType.Delete, opacity: 0 })}}.width('90%').margin({ top: 15, bottom: 15 })}3、完成、删除目标
左滑目标即可看到完成和删除按钮
使用的是ListItem.swipeAction方法
核心代码如下
@BuilderitemEnd(item: TargetInfoVo) {Row() {// 构建尾端滑出组件Button({ type: ButtonType.Circle }) {Image($r('app.media.icon_finish')).width(40).aspectRatio(1)}.onClick(async () => {// 完成未完成的目标if (item.status === '1') {showToast('当前目标已完成，无需重复点击')return}// 完成目标await targetInfoApi.completeTargetInfo({ id: item.id })showToast('目标已完成')router.replaceUrl({ url: RouterConstant.VIEWS_LEARN_TARGET })}).margin({ right: 10 })// 构建尾端滑出组件Button({ type: ButtonType.Circle }) {Image($r('app.media.icon_delete')).width(40).aspectRatio(1)}.margin({ right: 10 }).onClick(async () => {IBestDialogUtil.open({title: "提示",message: "是否确认删除当前目标？",showCancelButton: true,onConfirm: async () => {// 删除目标await targetInfoApi.deleteTargetInfo({ id: item.id })showToast('删除目标成功')router.replaceUrl({ url: RouterConstant.VIEWS_LEARN_TARGET })}})})}.justifyContent(FlexAlign.SpaceBetween)}4、编写学习目标接口方法
import http from '../request/Request'
import { PageParam, PageVo, TargetInfoAddParam,TargetInfoCompleteParam,TargetInfoCountVo,TargetInfoDeleteParam,TargetInfoEditParam,TargetInfoVo } from './TargetInfoApi.type'/*** 目标内容接口*/
class TargetInfoApi {/*** 获取用户整体目标完成进度统计*/getTargetInfoCount = (): Promise<TargetInfoCountVo> => {return http.get('/v1/target/count')}/*** 分页查询用户整体目标*/pageListTargetInfo = (data: PageParam): Promise<PageVo<TargetInfoVo>> => {return http.get('/v1/target/page?page=' + data.page + '&&pageSize=' + data.pageSize)}/*** 新增目标*/addTargetInfo = (data: TargetInfoAddParam) => {return http.post('/v1/target/add', data)}/*** 修改目标*/editTargetInfo = (data: TargetInfoEditParam) => {return http.post('/v1/target/edit', data)}/*** 完成目标*/completeTargetInfo = (data: TargetInfoCompleteParam) => {return http.post('/v1/target/complete', data)}/*** 删除目标*/deleteTargetInfo = (data: TargetInfoDeleteParam) => {return http.post('/v1/target/delete', data)}}const targetInfoApi = new TargetInfoApi();export default targetInfoApi as TargetInfoApi;/*** 用户整体目标完成进度统计*/
export interface TargetInfoCountVo {/*** 总目标数量*/totalQuantity: number/*** 完成目标的数量*/completeQuantity: number/*** 更新时间*/updateTime: string
}/*** 新增目标*/
export interface TargetInfoAddParam {/*** 目标内容*/content: string}/*** 修改目标*/
export interface TargetInfoEditParam {/*** 目标内容*/content: string/*** 目标内容id*/id: number}/*** 完成目标*/
export interface TargetInfoCompleteParam {/*** 目标内容id*/id: number}/*** 删除目标*/
export interface TargetInfoDeleteParam {/*** 目标内容id*/id: number}/*** 用户目标内容详情*/
export interface TargetInfoVo extends BaseTime {/*** 目标内容id*/id: number/*** 目标内容*/content: string/*** 目标状态：0未完成 1完成*/status: string/*** 创建时间字符串格式*/time: string
}/*** 时间*/
export interface BaseTime {/*** 创建时间*/createTime?: Date/*** 更新时间*/updateTime?: Date
}/*** 分页参数*/
export interface PageParam {/*** 当前页*/page?: number/*** 每一页展示的数据条数*/pageSize?: number
}/*** 分页响应参数*/
export interface PageVo<T> {current: number,size: number,total: number,records: Array<T>
}学习平台和面试平台
学习平台和面试平台跟首页差不多雷同，所以在这里就不说了
