详细开发步骤

1. 项目初始化

1. 在DevEco Studio中创建新项目
2. 选择"Application" -> "Empty Ability"
3. 项目命名为"WholeHouseCustomization"
4. 确保勾选"Enable CodeGenie"和"Enable Super Visual"选项

2. 主界面设计 (main_page.xml)

    this.$app.router.push({
      uri: "pages/userCenter"
    });

  // 其他方法...
}

5. 3D设计工具业务逻辑 (design_tool_page.js)

export default {
  data: {

      this.floorMaterials = floorRes.data;
      
      // 设置默认材料
      if (this.wallMaterials.length > 0) {
        this.currentWallMaterial = this.wallMaterials[0];
      }
      if (this.floorMaterials.length > 0) {
        this.currentFloorMaterial = this.floorMaterials[0];
      }
    }).catch(error => {
      this.$page.showToast("加载材料数据失败");
    });
  },
  
  // 显示房间选择
  showRoomSelection() {
    this.$app.router.push({
      uri: "pages/roomSelection",
      params: { currentRoom: this.currentRoom }
    });
  },
  
  // 切换材料面板显示状态
  toggleMaterialPanel() {
    this.showMaterialPanel = !this.showMaterialPanel;
  },
  
  // 添加家具到画布
  addFurniture(furniture) {
    const newFurniture = {
      ...furniture,
      id: Date.now(), // 使用时间戳作为临时ID
      x: 100, // 默认位置
      y: 100,
      rotation: 0
    };
    
    this.placedFurniture.push(newFurniture);
    this.$page.showToast(`已添加 ${furniture.name}`);
  },
  
  // 选择家具
  selectFurniture(furnitureId) {
    this.selectedFurniture = this.placedFurniture.find(
      item => item.id === furnitureId
    );
    
    // 显示家具操作菜单
    this.showFurnitureMenu = true;
  },
  
  // 应用墙面材料
  applyWallMaterial(material) {
    this.currentWallMaterial = material;
    this.$page.showToast(`已应用 ${material.name} 墙面`);
  },
  
  // 应用地面材料
  applyFloorMaterial(material) {
    this.currentFloorMaterial = material;
    this.$page.showToast(`已应用 ${material.name} 地面`);
  },
  
  // 保存设计方案
  saveDesign() {
    const designData = {

      furniture: this.placedFurniture,
      wallMaterial: this.currentWallMaterial,
      floorMaterial: this.currentFloorMaterial,
      createTime: new Date().toISOString()
    };
    
    this.$app.http.post('/design/save', designData)
      .then(response => {
        this.$page.showToast("设计方案保存成功");
      })
      .catch(error => {
        this.$page.showToast("保存失败");
      });
  },
  
  // 3D预览
  preview3D() {
    const designData = {
      roomType: this.currentRoom,
      furniture: this.placedFurniture,
      materials: {
        wall: this.currentWallMaterial,

    this.$app.router.push({
      uri: "pages/3dPreview",
      params: { designData: JSON.stringify(designData) }
    });
  }
}

6. 报价系统实现

// quote_system_page.js
export default {
  data: {
    designData: null,
    quoteItems: [],
    totalPrice: 0,
    discount: 0,
    finalPrice: 0
  },
  
  onInit(params) {
    this.designData = JSON.parse(params.designData);
    this.calculateQuote();
  },
  
  calculateQuote() {
    // 计算材料费用
    const wallArea = this.designData.roomInfo.wallArea;
    const floorArea = this.designData.roomInfo.floorArea;
    
    const wallCost = wallArea * this.designData.materials.wall.price;
    const floorCost = floorArea * this.designData.materials.floor.price;
    
    // 计算家具费用
    let furnitureCost = 0;
    const furnitureItems = [];
    
    this.designData.furniture.forEach(item => {
      furnitureCost += item.price;
      furnitureItems.push({
        name: item.name,
        quantity: 1,

高级功能实现

1. AR实景预览

// ar_preview_page.js
export default {
  data: {
    designData: null,
    arReady: false,
    trackingStatus: "未开始"
  },
  
  onInit(params) {
    this.designData = JSON.parse(params.designData);
  },
  
  onReady() {
    this.initAREngine();
  },
  
  initAREngine() {
    const config = {
      mode: "FURNITURE_PLACEMENT",
      designData: this.designData
    };
    
    this.$app.arEngine.init(config)
      .then(() => {
        this.arReady = true;
      })
      .catch(error => {
        this.$page.showToast("AR引擎初始化失败");
      });
  },
  
  startARTracking() {
    this.$app.arEngine.startTracking()
      .then(() => {
        this.trackingStatus = "跟踪中";
        this.placeFurnitureInAR();
      })
      .catch(error => {
        this.$page.showToast("开始跟踪失败");
      });
  },
  
  placeFurnitureInAR() {
    this.designData.furniture.forEach(furniture => {
      this.$app.arEngine.placeObject({
        model: furniture.model3d,
        position: furniture.position,
        scale: furniture.scale
      });
    });
  },
  
  takeARSnapshot() {
    this.$app.arEngine.takeSnapshot()
      .then(imageUri => {
        this.$page.showToast("截图已保存");
        // 保存或分享图片
      })
      .catch(error => {
        this.$page.showToast("截图失败");
      });
  }
}

2. 客户管理模块

// client_management_page.js
export default {
  data: {
    clients: [],
    searchText: "",
    activeFilter: "all",
    showClientForm: false,
    newClient: {
      name: "",
      phone: "",
      address: "",
      budget: "",
      preferences: []
    }
  },
  
  onInit() {
    this.loadClients();
  },
  
  loadClients() {
    this.$app.http.get('/clients')
      .then(response => {
        this.clients = response.data;
      })
      .catch(error => {
        this.$page.showToast("加载客户列表失败");
      });
  },
  
  searchClients() {
    this.$app.http.get('/clients/search', { params: { q: this.searchText } })
      .then(response => {
        this.clients = response.data;
      })
      .catch(error => {
        this.$page.showToast("搜索失败");
      });
  },
  
  filterClients(filter) {
    this.activeFilter = filter;
    let url = '/clients';
    
    if (filter !== 'all') {
      url += `?status=${filter}`;
    }
    
    this.$app.http.get(url)
      .then(response => {
        this.clients = response.data;
      })
      .catch(error => {
        this.$page.showToast("筛选失败");
      });
  },
  
  showClientDetails(clientId) {
    this.$app.router.push({
      uri: "pages/clientDetail",
      params: { clientId: clientId }
    });
  },
  
  addNewClient() {
    this.$app.http.post('/clients', this.newClient)
      .then(response => {
        this.$page.showToast("客户添加成功");
        this.loadClients();
        this.showClientForm = false;
        this.resetNewClientForm();
      })
      .catch(error => {
        this.$page.showToast("添加客户失败");
      });
  },
  
  resetNewClientForm() {
    this.newClient = {
      name: "",
      phone: "",
      address: "",
      budget: "",
      preferences: []
    };
  }
}

系统集成与部署

1. 权限配置 (config.json)

{
  "app": {
    "bundleName": "com.example.wholehousecustomization",
    "vendor": "example",
    "version": {
      "code": 1,
      "name": "1.0.0"
    }
  },
  "deviceConfig": {},
  "module": {
    "package": "com.example.wholehousecustomization",
    "name": ".MyApplication",
    "reqPermissions": [
      {
        "name": "ohos.permission.INTERNET"
      },
      {
        "name": "ohos.permission.CAMERA"
      },
      {
        "name": "ohos.permission.READ_MEDIA"
      },
      {
        "name": "ohos.permission.WRITE_MEDIA"
      },
      {
        "name": "ohos.permission.ACTIVITY_MOTION"
      }
    ],
    "abilities": [
      {
        "name": "MainAbility",
        "icon": "$media:icon",
        "label": "$string:MainAbility_label",
        "launchType": "standard"
      }
    ]
  }
}

2. 后端API集成

// utils/http.js
export default {
  baseUrl: "https://api.yourcompany.com/v1",
  
  get(url, params = {}) {
    return new Promise((resolve, reject) => {
      fetch.fetch({
        url: this.baseUrl + url,
        data: params,
        success: (response) => {
          if (response.code === 200) {
            resolve(response.data);
          } else {
            reject(response.message);
          }
        },
        fail: (error) => {
          reject(error);
        }
      });
    });
  },
  
  post(url, data) {
    return new Promise((resolve, reject) => {
      fetch.fetch({
        url: this.baseUrl + url,
        method: "POST",
        data: data,
        success: (response) => {
          if (response.code === 200) {
            resolve(response.data);
          } else {
            reject(response.message);
          }
        },
        fail: (error) => {
          reject(error);
        }
      });
    });
  }
};

性能优化建议

1. ​​图片资源优化​​：

   • 使用WebP格式替代PNG/JPG
   • 实现懒加载和渐进式加载
   • 根据设备分辨率加载不同尺寸的图片

2. ​​数据缓存策略​​：

   • 使用HarmonyOS的Data Ability缓存常用数据
   • 实现本地数据库存储客户信息和设计方案
   • 设置合理的API缓存策略

3. ​​AR性能优化​​：

   • 降低3D模型的多边形数量
   • 使用LOD(Level of Detail)技术
   • 在低端设备上关闭阴影和反射效果

4. ​​代码优化​​：

   • 使用CodeGenie的组件复用功能
   • 将复杂逻辑拆分为多个子组件
   • 避免在UI线程执行耗时操作

总结

通过HarmonyOS 5的CodeGenie工具，我们可以高效开发全屋定制方案公司App，实现以下核心功能：

• 客户信息管理与沟通记录
• 可视化全屋设计方案创建
• 3D/AR实景预览功能
• 智能材料搭配与替换
• 自动报价系统生成
• 设计方案分享与协作

这种开发方式大大提高了开发效率，同时保证了应用的性能和用户体验，非常适合家居定制行业的需求。
