Existing library for quick menu like in Google+ app?
<p>A design pattern I've noticed being used recently in some Android apps is a simple textual list menu similar to QuickActions in that it pops up in a speech-bubble-like View when summoned. The Google+ app uses it for overflow items, for example.</p>

<p>Does anybody know of a library that'll let me easily implement these kinds of menus in my own app or, if not, what the most straightforward way of doing it from scratch would be?</p>

<p>Many thanks.</p>
