Progress的ScaleRing样式，如何实现loading效果

@Entry 
@Component 
struct ProgressExample { 
  @State progressValue: number = 0 
  @State animationId: number | null = null 
  build() { 
    Column({ space: 15 }) { 
      Progress({ value: 0, total: 100, type: ProgressType.ScaleRing }) 
        .color(Color.Orange) 
        .value(this.progressValue) 
        .width(100) 
        .style({ strokeWidth: 10, scaleCount: 20, scaleWidth: 5, enableSmoothEffect: true }) 
      Progress({ value: 0, total: 100, type: ProgressType.ScaleRing }) 
        .color(Color.Red) 
        .value(this.progressValue) 
        .width(100) 
        .style({ strokeWidth: 10, scaleCount: 20, scaleWidth: 5, enableSmoothEffect: true }) 
      Button('开始动画').onClick(() => { 
        if (this.animationId === null) { 
          this.animationId = setInterval(() => { 
            this.progressValue++ 
            if (this.progressValue == 100) { 
              this.progressValue = 0 
            } 
          }, 10) 
        } 
        console.log(this.animationId.toString()) 
      }) 
      Button('结束动画').onClick(() => { 
        clearInterval(this.animationId) 
        this.animationId = null 
        this.progressValue = 0 
      }) 
    }.width('100%').padding({ top: 5 }) 
  } 
}
