ContentLoadingProgressBar

Added in 1.1.0

Kotlin |Java

public class ContentLoadingProgressBar extends ProgressBar

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).

Summary

Public constructors
`ContentLoadingProgressBar(@NonNull Context context)`
`ContentLoadingProgressBar( @NonNull Context context, @Nullable AttributeSet attrs )`

Public methods
`void`	`hide()` Hide the progress view if it is visible.
`void`	`onAttachedToWindow()`
`void`	`onDetachedFromWindow()`
`void`	`show()` Show the progress view after waiting for a minimum delay.
