Android: Create bigger Floating Action Button with bigger icon
<p>I want to create a bigger Floating Action Button (FAB), more than the usual 56 dp, with a bigger icon inside.
(For my purpose an icon will never be self-explanatory so I will create a png-file containing a short text and use this png as icon.)</p>

<p>Increasing the size of the FAB works fine:<br>
as i don't use the mini-FloatingActionButton, i redefined the mini-button-size.<br>
in my <strong>layout-xml</strong> i specify: </p>

<pre><code>&lt;android.support.design.widget.FloatingActionButton
    ...
    app:fabSize="mini"
    ....
</code></pre>

<p>and in the <strong>dimensions.xml</strong> i redefine the size for the mini-fab: </p>

<pre><code>&lt;dimen name="fab_size_mini"&gt;80dp&lt;/dimen&gt;
</code></pre>

<p>However, I didn't manage to get a bigger icon on the FAB.
I tried icons with different dp's from the material icons library - no success. Also setting a padding on the FAB-layout did not work.</p>

<p>Any suggestions? Thanks!</p>
