【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
   @Component
   struct 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
