Expanding Toolbar which contains EditText
<p>I am having my first contact with expanding/collapsing toolbars. I've got some results following <a href="https://guides.codepath.com/android/Handling-Scrolls-with-CoordinatorLayout#expanding-and-collapsing-toolbars" rel="noreferrer">this great tutorial</a>.</p>

<p>Now, I would like (if that's possible) to replace the static title (see title "Anthoriro" below)</p>

<p><a href="https://i.stack.imgur.com/0D14c.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/0D14c.gif" alt="enter image description here"></a></p>

<p>for couple of <code>EditText</code>s so that I have something similar to this</p>

<p><a href="https://i.stack.imgur.com/InI8f.png" rel="noreferrer"><img src="https://i.stack.imgur.com/InI8f.png" alt="enter image description here"></a></p>

<p>In this case, the text to be shown when the toolbar is collapsed would be the title <em>Project Priorities</em>.</p>
