HarmonyOS listItem不支持设置安全区域 ，有规避方案 让listItem超出安全区域嘛

onPageShow(): void {
  let windowClass = AppStorage.get("windowStage") as window.WindowStage
  windowClass.getMainWindowSync().setWindowLayoutFullScreen(true)
}

onPageHide(): void {
  let windowClass = AppStorage.get("windowStage") as window.WindowStage
  windowClass.getMainWindowSync().setWindowLayoutFullScreen(false)
}
