Retrieving drawable from overlayitem

Is there any clever way of retrieving the Drawable from an OverlayItem?

I want to store the Drawable of an OverlayItem before setting a new Drawable on it, to be able to revert afterwards, but I can't find any way of actually retrieving the current Drawable开发者_JS百科.

You are the one defining the Drawable in the first place. Make note of what it is at the time you set it up or change it. Most likely, you will need to create your own subclass of OverlayItem for this.
