【Harmony OS】【ARK UI】js或ETS如何获取状态栏高度

 在Harmony OS项目怎么获取状态高度？
在开发中我们可以参考窗口的getAvoidArea和getTopWindow的api，分为“代码实现”,“运行效果”两个步骤进行实现

1. 代码实现
   全部代码如下

   import window from '@ohos.window';@Entry@Componentstruct Index {  @State statusBarHeight:number=-1  public  click(){    window.getTopWindow((err, data) => {      var windowClass = data;      var type = window.AvoidAreaType.TYPE_SYSTEM;      windowClass.getAvoidArea(type, (err, data) => { if (err) {   console.error('Failed to obtain the area. Cause:' + JSON.stringify(err));   return; } this. statusBarHeight = data.topRect.height; console.log("statusBarHeight====>>>>"+this.statusBarHeight);      });    });  }  build() {    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {      Text('获取状态栏高度') .fontSize(50) .fontWeight(FontWeight.Bold)      .onClick(this.click.bind(this))      Text('状态栏高度'+this.statusBarHeight) .fontSize(50) .margin(10)      .fontColor(Color.Red)    }    .width('100%')    .height('100%')  }}

2.运行效果
效果如下
