How can I include a button in a Toast notification?
<p>First of all, I know this has been asked before: <a href="http://stackoverflow.com/questions/3308975/android-button-in-custom-toast">Android : Button in custom Toast</a>.
This is nearly an exact duplicate, but I think that it warrants a new question based on the fact that it's been used in apps, namely Gmail for ICS (it appears when you delete a message).</p>

<p>The linked question says that it's not possible to include a button in a <code>Toast</code> because <code>Toast</code>s cannot be focused. Is this wrong, outdated, or did Gmail find a way around it?</p>
