HarmonyOS 在定时器里面改变@state修饰的变量，无法更新UI吗？

将函数function写成了封装函数的形式就可以了

@Entry
@Component
struct Index {
  @State acSetValve: number = 0;

  aboutToAppear(): void {
    setInterval(() => {
      this.acSetValve += 200;
      console.log('hahhah' + this.acSetValve)
    } ,100)
  }

  build() {
    Row() {
      Column() {
        Text(this.acSetValve.toString())
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
      }
      .width('100%')
    }
    .height('100%')
  }
}
