public class RoundProgressBar
extends ProgressBar

表示 UI 上的圆形进度条。

圆形进度条可以是确定的或不确定的类型。它显示在 UI 或通知中，而不会中断用户操作。此类继承自 ProgressBar 并支持自定义元素对象和背景以显示不确定或确定的进度。有关详细信息，请参阅 ProgressBar.setInfiniteModeElement(ohos.agp.components.element.Element)、ProgressBar.setProgressBackgroundElement(ohos.agp.components.element.Element) 和 ProgressBar.setProgressElement(ohos.agp.components.element.Element)。上述方法通常与 ShapeElement、ShapeElement#ARC 和 ShapeElement#OVAL 一起使用。如果设置了其他形状，结果可能无法预测。如果您需要将默认元素对象替换为自定义元素对象，请注意 ShapeElement#setShape(int)) 中的参数。

不确定的回合进度

当操作所需的时间不确定时，使用不确定的圆形进度条。

确定回合进度

当需要显示某个操作的具体进度值时，使用确定的圆形进度条。您可以使用 ProgressBar.setProgressValue(int) 来更新当前进度。默认情况下，当圆形进度条上显示的进度值达到 100 时，操作完成。
