       ↳ androidx.core.widget.ContentLoadingProgressBar

ContentLoadingProgressBar implements a ProgressBar that waits a minimum time to be dismissed before showing. Once visible, the progress bar will be visible for a minimum amount of time to avoid "flashes" in the UI when an event could take a largely variable time to complete (from none, to a user perceivable amount)
