HarmonyOS Toggle 问题

参考以下代码

@Entry
@Component
struct ScrollExample {
  scroller: Scroller = new Scroller()
  private arr: number[] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
  @State @Watch('statusChange') isOn: boolean = false
  build() {
    Row() {

      Toggle({ type: ToggleType.Switch, isOn: $$this.isOn })
        .selectedColor('#007DFF')
        .switchPointColor('#FFFFFF')
        .onChange((isOn: boolean) => {

          if (isOn){
            setTimeout(()=>{
              this.isOn = !isOn

            },3000)

          }else {
            this.isOn = isOn
          }

        })
    }.width('100%').height('100%').backgroundColor(0xDCDCDC)
  }
  statusChange(){

  }
}
