HarmonyOS NEXT 实战之元服务:静态案例效果(二)
背景:
前几篇学习了元服务,后面几期就让我们开发简单的元服务吧,里面丰富的内容大家自己加,本期案例 仅供参考
先上本期效果图 ,里面图片自行替换
效果图代码案例如下:
- Index里面实现
import { authentication } from '@kit.AccountKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { AddressExchangeViewComponent } from './AddressExchangeViewComponent';
export const DATA_CONFIG: Record<string, number> = {
'NUMBER_LEN': 7, // 数字个数
'DURATION_TIME': 200, // 动画时长
'MILLENNIAL_LEN': 3 // 千分位长度
}
export const STYLE_CONFIG: Record<string, number> = {
'ITEM_GUTTER': 12, // 元素间距
'ITEM_HEIGHT': 26, // 数字元素高度
'TEXT_MARGIN': 2, // 文本间距
'PADDING_TOP': 32 // 顶部边距
}
@Entry
@Component
struct Index {
build() {
Column({ space: STYLE_CONFIG.ITEM_GUTTER }) {
Text($r('app.string.EntryAbility_label')).fontColor(Color.White)
.fontSize($r('sys.float.ohos_id_text_size_headline8'))
.width($r('app.string.digital_scroll_animation_max_size'))
.textAlign(TextAlign.Start)
.margin({left:25})
Row({ space: 10 }) {
Text(this.getDate())
.fontSize($r('app.string.ohos_id_text_size_headline'))
.fontWeight(FontWeight.Medium)
.height(30)
.fontColor(Color.White)
Text('天气 多云 18℃')
.height(30)
}
.width('100%').margin({left:15})
AddressExchangeViewComponent()
}
.padding({
top: STYLE_CONFIG.PADDING_TOP
})
.margin({ top: 60 })
.width($r('app.string.digital_scroll_animation_max_size'))
.height($r('app.string.digital_scroll_animation_max_size'))
.linearGradient({
colors: [[$r('app.color.digital_scroll_animation_background_color'), 0.0],
[$r('sys.color.ohos_id_color_background'), 0.3]]
})
}
aboutToAppear() {
hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate');
this.loginWithHuaweiID();
}
/**
* Sample code for using HUAWEI ID to log in to atomic service.
* According to the Atomic Service Review Guide, when a atomic service has an account system,
* the option to log in with a HUAWEI ID must be provided.
* The following presets the atomic service to use the HUAWEI ID silent login function.
* To enable the atomic service to log in successfully using the HUAWEI ID, please refer
* to the HarmonyOS HUAWEI ID Access Guide to configure the client ID and fingerprint certificate.
*/
private loginWithHuaweiID() {
// Create a login request and set parameters
let loginRequest = new authentication.HuaweiIDProvider().createLoginWithHuaweiIDRequest();
// Whether to forcibly launch the HUAWEI ID login page when the user is not logged in with the HUAWEI ID
loginRequest.forceLogin = false;
// Execute login request
let controller = new authentication.AuthenticationController();
controller.executeRequest(loginRequest).then((data) => {
let loginWithHuaweiIDResponse = data as authentication.LoginWithHuaweiIDResponse;
let authCode = loginWithHuaweiIDResponse.data?.authorizationCode;
// Send authCode to the backend in exchange for unionID, session
}).catch((error: BusinessError) => {
hilog.error(0x0000, 'testTag', 'error: %{public}s', JSON.stringify(error));
if (error.code == authentication.AuthenticationErrorCode.ACCOUNT_NOT_LOGGED_IN) {
// HUAWEI ID is not logged in, it is recommended to jump to the login guide page
}
});
}
private getDate() {
const now = new Date();
const year = now.getFullYear();
const month = now.getMonth() + 1; // 注意:月份是从0开始计数的
const day = now.getDate();
const hours = now.getHours();
const minutes = now.getMinutes();
const seconds = now.getSeconds();
return `${year} 年 ${month} 月 ${day} 日`
}
}
- AddressExchangeViewComponent 里面实现

}
//消息相关
@Builder
msgRelated(src: Resource, title: string, onClick?: () => void) {
