HarmonyOS如何使用Progress中的ring圆环加载样式

@Entry 
@Component 
struct Progress_Ring { 
  @State progressValue: number = 100 
  @State animationId: number | null = null 
  private gradientColor: LinearGradient = new LinearGradient([{ color: Color.Transparent, offset: 0.2 }, 
    { color: Color.White, offset: 0.5 }]) 
  build() { 
    Column({ space: 15 }) { 
      Progress({ value: 0, total: 100, type: ProgressType.Ring }) 
         .color("#00FFFFF") 
        .value(this.progressValue) 
        .width(100) 
        .style({ strokeWidth: 10, scaleCount: 20, scaleWidth: 5, enableSmoothEffect: true }) 
        .backgroundColor(Color.White) 
        .rotate({ 
          x: 0, 
          y: 1, 
          z: 0, 
          centerX: '50%', 
          centerY: '50%', 
          angle: 180 
        }) 
      Button('开始动画').onClick(() => { 
        if (this.animationId === null) { 
          this.animationId = setInterval(() => { 
            this.progressValue-- 
            if (this.progressValue == 0) { 
              this.progressValue = 100 
            } 
          }, 10) 
        } 
        console.log(this.animationId.toString()) 
      }) 
      Button('结束动画').onClick(() => { 
        clearInterval(this.animationId) 
        this.animationId = null 
        this.progressValue = 100 
      }) 
    }.width('100%').padding({ top: 5 }).backgroundColor(Color.Red) 
  } 
}
