基于HarmonyOS Next的智能房产装修管家开发实战
基于HarmonyOS Next的智能房产装修管家开发实战
在房产与装修领域,HarmonyOS Next为开发者提供了前所未有的创新工具。本文将结合AppGallery Connect(AGC)服务与ArkTS语言,手把手教你打造一个功能全面的智能房产管家应用,涵盖房源管理、3D看房、装修设计、材料采购等核心场景,让开发过程既简单又有趣。
一、项目规划与基础搭建
技术工具箱:
- HarmonyOS SDK 5.0
- ArkTS声明式UI
- AGC核心服务:云数据库、云存储、位置服务
三步快速启动:
- 在AGC控制台创建项目并启用Cloud DB
- 设计房源数据结构
- 配置应用权限
// 房源数据模型 Property.ets @Observed export class Property { @PrimaryKey id: string = ''; // 唯一ID title: string = ''; // 房源标题 address: string = ''; // 详细地址 price: number = 0; // 价格(单位:万元) area: number = 0; // 面积(㎡) @StorageLink('favorite') isFavorite: boolean = false; // 收藏状态 }
二、智能房源管理系统
核心功能:
- 地图找房
- 智能筛选
- 收藏管理
// PropertyManager.ets - 房源管理 import { cloudDB, cloudStorage } from **********'; import { geolocation } from **********'; export class PropertyManager { private static cloudDBZone: cloudDB.CloudDBZone | null = null; // 初始化云数据库 static async init() { try { const agcCloudDB = await cloudDB.getAGConnectCloudDB(); this.cloudDBZone = await agcCloudDB.openCloudDBZone( new cloudDB.CloudDBZoneConfig('PropertyDB') ); } catch (err) { console.error('数据库初始化失败', err.message); } } // 获取附近房源 static async getNearbyProperties(radius: number = 5): Promise<Property[]> { try { const location = await geolocation.getCurrentLocation(); const query = cloudDB.CloudDBZoneQuery.where(Property) .withinDistance('coordinates', location, radius * 1000); const snapshot = await this.cloudDBZone.executeSnapshotQuery(query); return await snapshot.getAllObjects(); } catch (err) { console.error('附近房源查询失败', err.message); return []; } } // 上传房源图片 static async uploadPropertyImage(propertyId: string, image: image.PixelMap) { try { const storage = cloudStorage.getStorageInstance(); const filePath = `properties/${propertyId}/${Date.now()}.jpg`; await storage.uploadFile({ filePath, data: image.toArrayBuffer() }); return filePath; } catch (err) { console.error('图片上传失败', err.message); return ''; } } }
三、沉浸式3D看房体验
技术亮点:
- 使用HarmonyOS的3D渲染能力
- 手势交互控制视角
- 分布式跨设备看房
// 3DViewer.ets - 3D看房组件 import { sceneView } from **********'; @Entry @Component struct PropertyViewer3D { @State currentAngle: number = 0; private sceneController: sceneView.SceneController | null = null; // 加载3D模型 private async loadModel(modelUrl: string) { try { this.sceneController = await sceneView.createSceneController(); await this.sceneController.loadScene(modelUrl); } catch (err) { console.error('3D模型加载失败', err.message); } } // 手势旋转控制 @Gesture rotationGesture: GestureGroup = GestureGroup(GestureMode.Sequence) .onRotate((event: GestureEvent) => { this.currentAngle += event.angle; this.sceneController?.rotateCamera(0, -this.currentAngle * 0.5, 0); }) build() { Stack() { // 3D场景容器 SceneView({ controller: this.sceneController }) .width('100%') .height('100%') // 控制面板 ViewerControls({ onRotateLeft: () => this.sceneController?.rotateCamera(0, 30, 0), onRotateRight: () => this.sceneController?.rotateCamera(0, -30, 0) }) } .gesture(this.rotationGesture) .onAppear(() => this.loadModel('https://model-repo/property123.glb')) } } // 分布式看房(手机→智慧屏) function startCrossDeviceViewing(propertyId: string) { distributedDeviceManager.startDeviceDiscovery({ deviceType: [DeviceType.SMART_TV] }).then(devices => { if (devices.length > 0) { distributedAbilityManager.startAbility({ deviceId: devices[0].deviceId, bundleName: 'com.property.app', abilityName: 'PropertyViewerAbility', parameters: { propertyId } }); } }); }
四、智能装修设计工具
核心功能:
- AR空间测量
- 虚拟家具摆放
- 装修方案保存
// RenovationDesigner.ets - 装修设计 import { arEngine } from **********'; import { drawing } from **********'; @Component struct DesignCanvas { @State furnitureItems: Furniture[] = []; private drawingCanvas: drawing.Canvas | null = null; // 添加家具 addFurniture(item: Furniture) { this.furnitureItems = [...this.furnitureItems, item]; } // AR测量 private async measureDistance() { try { const result = await arEngine.measureDistance(); showToast(`距离测量: ${result.distance.toFixed(2)}米`); } catch (err) { console.error('AR测量失败', err.message); } } build() { Column() { // 设计画布 Canvas(this.drawingCanvas) .width('100%') .height('70%') .backgroundColor('#F5F5F5') .onReady((canvas) => { this.drawingCanvas = canvas; }) // 家具库 FurniturePalette({ onSelect: (item) => this.addFurniture(item) }) Button('AR测量').onClick(() => this.measureDistance()) } } } // 保存设计方案到云端 async function saveDesign(design: RenovationDesign) { try { const storage = cloudStorage.getStorageInstance(); const filePath = `designs/${design.id}.json`; await storage.uploadFile({ filePath, data: new TextEncoder().encode(JSON.stringify(design)) }); return true; } catch (err) { console.error('设计方案保存失败', err.message); return false; } }
五、建材商城与交易系统
集成功能:
- 材料分类浏览
- 虚拟样板间展示
- 安全支付
// MaterialStore.ets - 建材商城 import { pay } from **********'; @Entry @Component struct BuildingMaterialStore { @State cartItems: MaterialItem[] = []; @State showARPreview: boolean = false; // 加入购物车 addToCart(item: MaterialItem) { this.cartItems = [...this.cartItems, item]; } // AR预览材料效果 previewInAR(item: MaterialItem) { this.showARPreview = true; arEngine.loadMaterialTexture(item.textureUrl); } // 结算支付 async checkout() { try { const total = this.cartItems.reduce((sum, item) => sum + item.price, 0); const result = await pay.requestPayment({ amount: total, description: '建材采购' }); if (result.code === 0) { showToast('支付成功!'); this.cartItems = []; } } catch (err) { console.error('支付失败', err.message); } } build() { Stack() { // 商品列表 MaterialCategoryList({ onItemSelect: (item) => this.addToCart(item), onARPreview: (item) => this.previewInAR(item) }) // 购物车悬浮按钮 ShoppingCartBadge(count: this.cartItems.length) .position({ x: '85%', y: '90%' }) .onClick(() => this.checkout()) // AR预览层 if (this.showARPreview) { ARPreviewLayer({ onClose: () => { this.showARPreview = false; } }) } } } }
六、装修进度管理
核心功能:
- 项目时间轴
- 施工监控接入
- 问题反馈系统
// RenovationTracker.ets - 进度跟踪 import { cloudDB } from **********'; import { calendar } from **********'; @Component struct ProjectTimeline { @Link projectId: string; @State timelineItems: TimelineEvent[] = []; // 加载项目时间线 async loadTimeline() { try { const query = cloudDB.CloudDBZoneQuery.where(TimelineEvent) .equalTo('projectId', this.projectId) .orderByAsc('date'); const snapshot = await cloudDBZone.executeSnapshotQuery(query); this.timelineItems = await snapshot.getAllObjects(); } catch (err) { console.error('时间线加载失败', err.message); } } // 添加日历提醒 addCalendarReminder(event: TimelineEvent) { calendar.addEvent({ title: `装修节点: ${event.title}`, startTime: event.date, endTime: event.date + 3600000, // 1小时后 reminderMinutes: [60, 1440] // 提前1天和1小时提醒 }); } build() { Column() { ForEach(this.timelineItems, (item) => { TimelineItem({ event: item, onRemind: () => this.addCalendarReminder(item) }) }) } .onAppear(() => this.loadTimeline()) } } // 施工监控组件 @Component struct ConstructionMonitor { @State liveVideoUrl: string = ''; // 获取实时监控流 async loadLiveStream(projectId: string) { try { const response = await fetch(`https://api.example.com/monitor/${projectId}`); this.liveVideoUrl = await response.text(); } catch (err) { console.error('监控流获取失败', err.message); } } build() { Video({ src: this.liveVideoUrl, controller: VideoController }) .controls(false) .autoPlay(true) .onAppear(() => this.loadLiveStream('project123')) } }
七、隐私与数据安全
关键防护措施:
- 位置信息模糊处理
- 敏感数据加密
- 权限动态申请
八、扩展应用场景
- AI装修风格推荐
- 建材用量计算器
- 装修贷款计算器
