(实现智能监护解决方案)
核心功能设计:
动态健康数据卡片(基于ArkTS声明式UI):
// HealthDataCard.ets
@Entry
@Component
struct HealthCard {
@State heartRate: number = 72
@State bloodOxygen: number = 98
build() {
Column() {
// 使用卡片折叠动画
Transition({ type: TransitionType.All, scale: { x: 0.9, y: 0.9 } })
{
Gauge({
value: this.heartRate,
min: 40,
max: 160
}).width(180)
// 条件式布局(新特性)
@BuilderConditional(this.bloodOxygen < 95)
buildWarning() {
Text("低血氧预警!")
.fontColor(Color.Red)
.margin(5)
}
}
}
.onClick(() => {
// 卡片点击触发详细分析页面
postCardAction(this, {
action: 'router',
abilityName: 'MainAbility',
params: {}
});
})
}
}
集成Push Kit实现分级推送:
// EmergencyService.ets
import push from '@ohos.push';
function initPushService() {
// 获取推送Token
push.getToken().then(data => {
console.log(`Push token: ${data.token}`);
});
// 处理推送消息
push.on('message', (data) => {
if (data.parameters?.emergencyLevel === 'CRITICAL') {
showFullScreenNotification(data);
} else {
showNormalNotification(data);
}
});
}
// 全屏紧急通知(新特性)
private showFullScreenNotification(data) {
let wantAgent = {
wants: [
{
bundleName: "com.example.health",
abilityName: "EmergencyAbility",
parameters: data
}
]
};
let notificationRequest: NotificationRequest = {
content: {
contentType: NotificationContentType.NOTIFICATION_TEXT,
text: data.alert
},
wantAgent: wantAgent,
// 使用持续通知特性
additionalFlags: [NotificationConstant.Flag.ONGOING_FLAG]
};
Notification.publish(notificationRequest);
}
跨设备体征数据库同步:
// DistributedDataManager.ets
import distributedData from '@ohos.data.distributedData';
let kvManager: distributedData.KVManager;
const options = {
kvStoreType: distributedData.KVStoreType.SINGLE_VERSION,
securityLevel: distributedData.SecurityLevel.S1
};
// 创建分布式数据库
distributedData.createKVManager('healthData', options).then((manager) => {
kvManager = manager;
return kvManager.getKVStore('healthStore', options);
}).then((store) => {
// 数据变更订阅)
store.on('dataChange', distributedData.SubscribeType.SUBSCRIBE_TYPE_ALL, (data) => {
console.log(`同步数据: ${JSON.stringify(data)}`);
updateLocalCache(data);
});
});
// 设备间数据同步
function syncData(deviceId: string) {
const predicate = new distributedData.RdbPredicates('HealthData');
kvStore.sync(deviceId, distributedData.SyncMode.PULL, predicate).then(() => {
showToast('数据同步成功');
});
}
HMS Core支付能力对接:
// PaymentService.ets
import iap from '@ohos.iap';
async function purchaseService() {
const productId = 'emergency_service_premium';
try {
// 获取最新支付参数
const purchaseParam = await iap.createPurchaseIntent({
productId: productId,
priceType: iap.PriceType.IN_APP_CONSUMABLE
});
// 调起支付界面
const result = await iap.purchase(this.context, purchaseParam);
if (result.purchaseState === iap.PurchaseState.PAID) {
activatePremiumService();
}
} catch (err) {
console.error(`支付失败: ${err.code}, ${err.message}`);
}
}
