Class Overview

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)

Public Methods

public void hide ()

Hide the progress view if it is visible. The progress view will not be hidden until it has been shown for at least a minimum show time. If the progress view was not yet visible, cancels showing the progress view.

public void onAttachedToWindow ()

This is called when the view is attached to a window. At this point it has a Surface and will start drawing. Note that this function is guaranteed to be called before onDraw(android.graphics.Canvas), however it may be called any time before the first onDraw -- including before or after onMeasure(int, int).

public void onDetachedFromWindow ()

This is called when the view is detached from a window. At this point it no longer has a surface for drawing.

public void show ()

Show the progress view after waiting for a minimum delay. If during that time, hide() is called, the view is never made visible.
