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 '@kit.AGConnectCloudKit';
import { geolocation } from '@kit.LocationKit';
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 '@kit.ThreeKit';
@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 '@kit.AREngineKit';
import { drawing } from '@kit.GraphicsKit';
@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 '@kit.PaymentKit';
@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 '@kit.AGConnectCloudKit';
import { calendar } from '@kit.CalendarKit';
@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
// 模糊显示具体位置 function maskLocation(address: string): string { const parts = address.split('号'); return parts.length > 1 ? `${parts[0]}号` : address; }
敏感数据加密
// module.json5配置 { "module": { "requestPermissions": [ { "name": "ohos.permission.APPROXIMATELY_LOCATION" } ], "metadata": { "encryptFields": ["price", "contact"] } } }
权限动态申请
async function requestCameraPermission() { const atManager = abilityAccessCtrl.createAtManager(); const result = await atManager.requestPermissionsFromUser( getContext(), ['ohos.permission.CAMERA'] ); return result.permissions[0].granted; }
八、扩展应用场景
AI装修风格推荐
import { ai } from '@kit.AIKit'; const styleAnalyzer = ai.createImageAnalyzer(); styleAnalyzer.analyze(photo).then(result => { showRecommendation(result.stylePreferences); });
建材用量计算器
// 根据房间尺寸计算材料用量 function calculateMaterial(area: number, material: Material): number { return Math.ceil(area / material.coveragePerUnit); }
装修贷款计算器
// 等额本息计算 function calculateLoan(principal: number, months: number, rate: number) { const monthlyRate = rate / 12; return principal * monthlyRate * Math.pow(1 + monthlyRate, months) / (Math.pow(1 + monthlyRate, months) - 1); }
