Harmony 状态栏 导航栏 高度获取 以及改变监听 并存储到 AppStorage

onWindowStageCreate(windowStage: window.WindowStage): void {
    let windowClass: window.Window = windowStage.getMainWindowSync(); // 获取应用主窗口
    // 2. 获取布局避让遮挡的区域
    let type = window.AvoidAreaType.TYPE_NAVIGATION_INDICATOR; // 以导航条避让为例
    let avoidArea = windowClass.getWindowAvoidArea(type);
    let bottomRectHeight = avoidArea.bottomRect.height; // 获取到导航条区域的高度
    AppStorage.setOrCreate('bottomRectHeight', bottomRectHeight);

    type = window.AvoidAreaType.TYPE_SYSTEM; // 以状态栏避让为例
    avoidArea = windowClass.getWindowAvoidArea(type);
    let topRectHeight = avoidArea.topRect.height; // 获取状态栏区域高度
    AppStorage.setOrCreate('topRectHeight', topRectHeight);

    // 3. 注册监听函数，动态获取避让区域数据
    windowClass.on('avoidAreaChange', (data) => {
      if (data.type === window.AvoidAreaType.TYPE_SYSTEM) {
        let topRectHeight = data.area.topRect.height;
        AppStorage.setOrCreate('topRectHeight', topRectHeight);
      } else if (data.type == window.AvoidAreaType.TYPE_NAVIGATION_INDICATOR) {
        let bottomRectHeight = data.area.bottomRect.height;
        AppStorage.setOrCreate('bottomRectHeight', bottomRectHeight);
      }
    });
}

使用方式

@StorageProp('bottomRectHeight')
bottomRectHeight: number = 0;
