Class Overview

DelayedConfirmationView provides a circular countdown timer, typically used to automatically confirm an operation after a short delay has elapsed. The delay is intended to give the user a chance to cancel the operation by tapping the View.

The developer can specify a countdown interval via setTotalTimeMs(long) and a listener via setListener(DelayedConfirmationView.DelayedConfirmationListener) to be called when the View is tapped or the time has elapsed.

More information on what are required XML attributes can be found at CircledImageView.
