title: How to manage Android toolbar
body: <p>I'm working on an app where I've put an android widget.toolbar as supportActionBar, but I couldn't find anything on how to manage its properties. I would like, for example, to modify and add elements in the overflow menu (I don't know if the name is correct at all, however I mean the one that appears when you click the 3-points default icon on the right corner. I'll post an image.) and to set a listener for each one of them. </p>
