Custom Overflow Menu Outside of ActionBar
<p>I need to implement a custom overflow menu with menu items and the overflow icon if the screen size cannot show all the icons.  I cannot use a side scroll since I am already inside an expanded list view.  I cannot use the Top or bottom action bar menu because the action will change based on what list item has been expanded. </p>

<p>So I would like to create my own overflow menu - similar to the gmail screenshots attached</p>

<p>Any ideas?  Apparently ABS can be used for this but I can't figure it out, please help :)</p>
