CircularProgressLayout adds a circular countdown timer behind the view it contains, typically used to automatically confirm an operation after a short delay has elapsed.

The developer can specify a countdown interval via setTotalTime(long) and a listener via setOnTimerFinishedListener(OnTimerFinishedListener) to be called when the time has elapsed after startTimer() has been called. Tap action can be received via View.setOnClickListener(OnClickListener) and can be used to cancel the timer via stopTimer() method.

Alternatively, this layout can be used to show indeterminate progress by calling setIndeterminate(boolean) method.

void setIndeterminate(boolean indeterminate)

Sets if progress should be shown as an indeterminate spinner.

void setOnTimerFinishedListener(CircularProgressLayout.OnTimerFinishedListener listener)

Sets the CircularProgressLayout.OnTimerFinishedListener to be notified when timer countdown is finished.

void setStartingRotation(float rotation)

Sets the starting rotation for the progress drawable to start from.

void setStrokeWidth(float strokeWidth)

Sets the stroke width of the progress drawable in pixels.

void setTotalTime(long totalTime)

Sets the total time in milliseconds for the timer to countdown to.

void startTimer()

Starts the timer countdown.

void stopTimer()
