public class RoundProgressBar extends ProgressBar
A round progress bar can be of the determinate or indeterminate type.
It is displayed on a UI or in a notification without interrupting user operations.
This class inherits from ProgressBar and supports custom element objects and backgrounds for displaying
indeterminate or determinate progress. For details, see ProgressBar.setInfiniteModeElement(ohos.agp.components.element.Element),
ProgressBar.setProgressBackgroundElement(ohos.agp.components.element.Element), and ProgressBar.setProgressElement(ohos.agp.components.element.Element).
The preceding methods are usually used with ShapeElement,
ShapeElement#ARC, and
ShapeElement#OVAL. If another shape is set, the result may be unpredictable.
If you need to replace the default element object with a custom one, be mindful of the parameters in
ShapeElement#setShape(int)).
An indeterminate round progress bar is used when the time required for the operation is uncertain.
An determinate round progress bar is used when the specific progress value of an operation needs to be displayed.
You can use ProgressBar.setProgressValue(int) to update the current progress.
By default, when the progress value displayed on the round progress bar reaches 100, the operation is
complete.
