使用 window获取:

window.getLastWindow(getContext(this))
      .then((windowClass: window.Window) => {
        let type = window.AvoidAreaType.TYPE_NAVIGATION_INDICATOR; // 以导航条避让为例
        let avoidArea = windowClass.getWindowAvoidArea(type);
        this.bottomSafeHeight = px2vp(avoidArea.bottomRect.height); // 获取到导航条区域的高度
        type = window.AvoidAreaType.TYPE_SYSTEM;
        avoidArea = windowClass.getWindowAvoidArea(type);
        this.statusBarHeight = px2vp(avoidArea.topRect.height);
        this.width = px2vp(windowClass.getWindowProperties().windowRect.width);
        this.height = px2vp(windowClass.getWindowProperties().windowRect.height);
        this.layoutWidth = this.width;
        this.layoutHeight = this.height - this.statusBarHeight - this.bottomSafeHeight;
      })
      .catch((error: Error) => {
      })
