HarmonyOS 全局触摸应用切后台未触发

示例参考如下：

import { window } from '@kit.ArkUI';

@Entry
@Component
struct AutoLogoutApp {
  @State isLoggedIn: boolean = false;
  @State timeoutId: number | null = null;
  @State idleTimeout: number = 5000; // 设置闲置时间为60秒
  @State message: string = '';
  windowClass: window.Window | undefined = undefined;

  onPageHide(): void {
    console.log('hide')
  }

  build() {
    Column() {
      if (!this.isLoggedIn) {
        Button('Login')
          .onClick(() => {
            this.login();
          });
      } else {
        Text('You are logged in. Interact to stay logged in.')
          .fontSize(20);
        Button('Logout')
          .onClick(() => {
            this.logout();
          });
      }
      if (this.message) {
        Text(this.message)
          .fontSize(16)
          .fontColor('#ff0000');
      }
    }
    .justifyContent(FlexAlign.Center)
    .width('100%')
    .height('100%')
    // 监听触摸事件，重置闲置计时器
    .onTouch(() => {
      this.resetIdleTimer();
    });
  }

  login() {
    this.isLoggedIn = true;
    this.message = '';
    this.resetIdleTimer();
  }

  logout() {
    this.isLoggedIn = false;
    this.clearIdleTimer();
    this.message = 'You have been logged out due to inactivity.';
  }

  resetIdleTimer() {
    if (this.timeoutId !== null) {
      clearTimeout(this.timeoutId);
    }
    this.timeoutId = setTimeout(() => {
      console.log('idleTimeout')
      this.logout();
    }, this.idleTimeout);
  }

  clearIdleTimer() {
    if (this.timeoutId !== null) {
      clearTimeout(this.timeoutId);
      this.timeoutId = null;
    }
  }
}
