二、核心代码实现
快捷指令管理服务

// ShortcutManagerService.ets
import shortcutManager from ‘@ohos.shortcutManager’;
import distributedData from ‘@ohos.data.distributedData’;

export class ShortcutManagerService {
private kvStore: distributedData.KVStore;
private readonly STORE_ID = ‘shortcut_store’;

async init() {
const kvManager = await distributedData.createKVManager({
bundleName: ‘com.example.shortcutcenter’
});
this.kvStore = await kvManager.getKVStore(this.STORE_ID, {
createIfMissing: true,
autoSync: true
});
async createShortcut(shortcut: ShortcutInfo): Promise<boolean> {

try {
  // 本地创建快捷方式
  await shortcutManager.publishShortcut({
    id: shortcut.id,
    label: shortcut.label,
    icon: shortcut.icon,
    wants: [{
      targetBundle: shortcut.targetBundle,
      targetAbility: shortcut.targetAbility,
      parameters: shortcut.parameters
    }]
  });
  
  // 同步到其他设备
  await this.kvStore.put(shortcut_${shortcut.id}, JSON.stringify({
    ...shortcut,
    deviceId: deviceInfo.deviceId,
    timestamp: new Date().getTime()
  }));
  
  return true;

catch (err) {

  console.error('创建快捷方式失败:', err);
  return false;

}

async getShortcuts(): Promise<ShortcutInfo[]> {
const entries = await this.kvStore.getEntries(‘shortcut_’);
return entries.map(entry => JSON.parse(entry.value));
subscribeShortcutChanges(callback: (shortcut: ShortcutInfo) => void) {

this.kvStore.on('dataChange', distributedData.SubscribeType.SUBSCRIBE_TYPE_ALL, (changes) => {
  changes.forEach(change => {
    if (change.key.startsWith('shortcut_')) {
      callback(JSON.parse(change.value));

});

});

}

场景化指令执行引擎

// ScenarioEngine.ets
import featureAbility from ‘@ohos.ability.featureAbility’;
import distributedData from ‘@ohos.data.distributedData’;

export class ScenarioEngine {
private kvStore: distributedData.KVStore;

async executeScenario(scenarioId: string) {
const scenario = await this.getScenario(scenarioId);
if (!scenario) return;

// 本地执行
await this.executeLocalActions(scenario.actions);

// 同步执行状态
await this.kvStore.put(scenario_status_${scenarioId}, JSON.stringify({
  status: 'executing',
  progress: 0,
  deviceId: deviceInfo.deviceId
}));

// 执行跨设备动作
await this.executeDistributedActions(scenario.distributedActions);

private async executeLocalActions(actions: Action[]) {

for (const action of actions) {
  try {
    await featureAbility.startAbility({
      bundleName: action.bundle,
      abilityName: action.ability,
      parameters: action.params
    });

catch (err) {

    console.error(执行动作 ${action.name} 失败:, err);

}

private async executeDistributedActions(actions: DistributedAction[]) {

for (const action of actions) {
  await this.kvStore.put(action_command_${action.device}, JSON.stringify({
    ...action,
    sourceDevice: deviceInfo.deviceId
  }));

}

设备自适应指令展示

// AdaptiveShortcutView.ets
@Component
struct AdaptiveShortcutView {
@Prop shortcut: ShortcutInfo;
@State isFavorite: boolean = false;

build() {
Column() {
// 根据设备类型显示不同布局
if (deviceInfo.deviceType === ‘phone’) {
this.renderMobileView();
else if (deviceInfo.deviceType === ‘tablet’) {

    this.renderTabletView();

else {

    this.renderTVView();

}

@Builder renderMobileView() {

Row() {
  Image(this.shortcut.icon)
    .width(40)
    .height(40)
  
  Column() {
    Text(this.shortcut.label)
      .fontSize(16)
    Text(this.shortcut.description)
      .fontSize(12)
      .opacity(0.7)

.margin({ left: 10 })

  Image(this.isFavorite ? 'heart_filled.png' : 'heart_outline.png')
    .width(20)
    .height(20)
    .onClick(() => this.toggleFavorite())

.padding(10)

@Builder renderTabletView() {

Column() {
  Image(this.shortcut.icon)
    .width(60)
    .height(60)
  
  Text(this.shortcut.label)
    .fontSize(18)
    .margin({ top: 5 })
  
  Text(this.shortcut.description)
    .fontSize(14)
    .opacity(0.7)
    .margin({ top: 3 })

.padding(15)

private toggleFavorite() {

this.isFavorite = !this.isFavorite;
// 同步收藏状态
const syncService = new ShortcutSyncService();
syncService.updateFavorite(this.shortcut.id, this.isFavorite);

}

三、关键技术创新点
多设备指令状态同步

// 状态同步算法
private async syncExecutionStatus(scenarioId: string) {
const devices = await this.getScenarioDevices(scenarioId);
const statusList = await Promise.all(
devices.map(d => this.kvStore.get(scenario_status_{scenarioId}_{d}))
);

// 计算总体进度
const overallProgress = statusList.reduce((sum, s) => {
const status = JSON.parse(s);
return sum + (status?.progress || 0);
}, 0) / devices.length;

// 更新全局状态
await this.kvStore.put(scenario_status_${scenarioId}_global, JSON.stringify({
progress: overallProgress,
timestamp: new Date().getTime()
}));

场景化指令组合引擎

// 场景组合器
class ScenarioComposer {
async createSmartScenario(context: ScenarioContext) {
// 1. 分析当前场景
const analysis = await this.analyzeContext(context);

// 2. 生成推荐指令组合
const recommended = this.generateRecommendations(analysis);

// 3. 优化执行顺序
return this.optimizeExecutionOrder(recommended);

private analyzeContext(context: ScenarioContext) {

// 分析时间、位置、设备状态等
return {
  isWorkHours: this.checkWorkHours(),
  location: await this.getLocationType(),
  connectedDevices: this.getDeviceCapabilities()
};

private generateRecommendations(analysis: ScenarioAnalysis) {

const scenarios = [];

if (analysis.isWorkHours) {
  scenarios.push(this.getWorkScenario());

if (analysis.location === ‘home’) {

  scenarios.push(this.getHomeScenario());

return scenarios;

}

设备能力自适应

// 设备适配器
class DeviceAdapter {
private static readonly DEVICE_CAPABILITIES = {
‘phone’: [‘launchApp’, ‘sendMessage’, ‘playMedia’],
‘tablet’: [‘launchApp’, ‘multitask’, ‘displayInfo’],
‘tv’: [‘playMedia’, ‘displayLargeInfo’],
‘watch’: [‘notify’, ‘simpleControl’]
};

filterActionsByDevice(actions: Action[], deviceType: string): Action[] {
const capabilities = DeviceAdapter.DEVICE_CAPABILITIES[deviceType] || [];
return actions.filter(action =>
capabilities.includes(action.type)
);
adaptShortcutDisplay(shortcut: ShortcutInfo, deviceType: string): DisplayInfo {

switch (deviceType) {
  case 'phone':
    return {
      viewType: 'mobile',
      iconSize: 40,
      showDescription: true
    };
  case 'tablet':
    return {
      viewType: 'medium',
      iconSize: 60,
      showDescription: true
    };
  case 'tv':
    return {
      viewType: 'large',
      iconSize: 100,
      showDescription: false
    };
  default:
    return {
      viewType: 'mobile',
      iconSize: 40,
      showDescription: false
    };

}

四、性能优化方案
指令预加载机制

// 预加载常用指令
private async preloadFrequentShortcuts() {
const history = await this.getUsageHistory();
const frequentIds = this.getTopFrequent(history, 5);

await Promise.all(
frequentIds.map(id =>
shortcutManager.prepareShortcut({
id,
prepareType: ‘preload’
})
)
);

分布式数据压缩

// 指令数据压缩
private async compressShortcut(shortcut: ShortcutInfo): Promise<Uint8Array> {
const jsonStr = JSON.stringify(shortcut);
return zlib.deflate(new TextEncoder().encode(jsonStr));
private async decompressShortcut(data: Uint8Array): Promise<ShortcutInfo> {

const decompressed = await zlib.inflate(data);
return JSON.parse(new TextDecoder().decode(decompressed));

智能缓存策略

// 三级缓存实现
class ShortcutCache {
private memoryCache: Map<string, ShortcutInfo> = new Map();
private diskCache: CacheStorage;
private cloudCache: CloudService;

async getShortcut(id: string): Promise<ShortcutInfo | null> {
// 1. 检查内存缓存
if (this.memoryCache.has(id)) {
return this.memoryCache.get(id);
// 2. 检查磁盘缓存

const diskData = await this.diskCache.match(id);
if (diskData) {
  const shortcut = JSON.parse(diskData);
  this.memoryCache.set(id, shortcut);
  return shortcut;

// 3. 从云端获取

const cloudData = await this.cloudCache.getShortcut(id);
if (cloudData) {
  await this.diskCache.put(id, JSON.stringify(cloudData));
  this.memoryCache.set(id, cloudData);
  return cloudData;

return null;

}

五、完整UI组件实现
快捷指令中心主界面

// ShortcutCenterPage.ets
@Entry
@Component
struct ShortcutCenterPage {
@State shortcuts: ShortcutInfo[] = [];
@State activeScenario: string = ‘home’;

private shortcutService = new ShortcutManagerService();
private scenarioEngine = new ScenarioEngine();

aboutToAppear() {
this.shortcutService.init();
this.loadShortcuts();

// 订阅指令变化
this.shortcutService.subscribeShortcutChanges(
  this.handleShortcutChange.bind(this)
);

build() {

Column() {
  // 场景选择器
  ScenarioSelector({
    active: this.activeScenario,
    onChange: (scenario) => {
      this.activeScenario = scenario;

})

  // 快捷指令网格
  Grid() {
    ForEach(this.shortcuts, (shortcut) => {
      GridItem() {
        AdaptiveShortcutView({
          shortcut,
          onClick: () => this.executeShortcut(shortcut)
        })

})

.columnsTemplate(‘1fr 1fr’)

  .rowsTemplate('1fr 1fr')
  
  // 添加按钮
  Button('添加快捷方式', { type: ButtonType.Capsule })
    .margin(20)
    .onClick(() => this.showAddDialog())

}

private async executeShortcut(shortcut: ShortcutInfo) {
await this.scenarioEngine.executeShortcut(shortcut.id);
private async loadShortcuts() {

this.shortcuts = await this.shortcutService.getShortcuts();

}

场景选择器组件

// ScenarioSelector.ets
@Component
struct ScenarioSelector {
@Prop active: string;
@Prop onChange: (scenario: string) => void;

@State scenarios: Scenario[] = [
id: ‘home’, name: ‘家庭模式’, icon: ‘home.png’ },

id: ‘work’, name: ‘工作模式’, icon: ‘work.png’ },

id: ‘car’, name: ‘车载模式’, icon: ‘car.png’ }

];

build() {
Scroll() {
Row() {
ForEach(this.scenarios, (scenario) => {
Column() {
Image(scenario.icon)
.width(40)
.height(40)
.opacity(this.active === scenario.id ? 1 : 0.6)

        Text(scenario.name)
          .fontSize(14)
          .opacity(this.active === scenario.id ? 1 : 0.6)

.onClick(() => this.onChange(scenario.id))

      .margin(10)
    })

.padding(10)

.scrollable(ScrollDirection.Horizontal)

}

六、项目部署与测试
权限配置

在module.json5中添加：

“requestPermissions”: [
“name”: “ohos.permission.SHORTCUT_MANAGER”

},
“name”: “ohos.permission.DISTRIBUTED_DATASYNC”

},
“name”: “ohos.permission.ABILITY_BACKGROUND”

},
“name”: “ohos.permission.GET_BUNDLE_INFO”

]

测试方案

// 快捷指令测试
describe(‘ShortcutManager’, () => {
it(‘should create and sync shortcut’, async () => {
const service = new ShortcutManagerService();
await service.init();

const testShortcut = {
  id: 'test_shortcut',
  label: '测试指令',
  icon: 'test.png',
  targetBundle: 'com.example.app',
  targetAbility: 'MainAbility'
};

const created = await service.createShortcut(testShortcut);
expect(created).toBe(true);

const shortcuts = await service.getShortcuts();
expect(shortcuts).toContainEqual(
  expect.objectContaining({ id: 'test_shortcut' })
);

});
});

// 场景执行测试
describe(‘ScenarioEngine’, () => {
it(‘should execute scenario actions’, async () => {
const engine = new ScenarioEngine();
const testScenario = {
id: ‘test_scenario’,
actions: [{
bundle: ‘com.example.app’,
ability: ‘MainAbility’,
name: ‘测试动作’
}]
};

await engine.executeScenario(testScenario);
expect(abilityMonitor.isAbilityStarted('MainAbility')).toBe(true);

});
});
