Setting a global minHeight and/or minWidth
<p>I've a drawable XML file, in which I set global parameters for my butons, using code like</p>

<pre><code>    &lt;shape android:shape="rectangle"&gt;
     &lt;corners android:radius="4dip" /&gt;
    &lt;stroke android:width="1dip" android:color="#555555" /&gt;
    &lt;solid android:color="#dddddd"/&gt;
    &lt;size android:height="20dip"/&gt;
    &lt;/shape&gt;
</code></pre>

<p>That's OK, but of course, as the default minHeight of button seems to be 48dp, the height of 20 does nothing.
I know I can use</p>

<pre><code>     android:minHeight="0dp"
     android:minWidth="0dp" 
</code></pre>

<p>but I want to set these values as "global" for all my buttons. Searching in Android Doc (<a href="https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape" rel="nofollow">https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape</a>), it seems minHeight and minWidth are not part of Shape Drawable.
So where can I set minHeight and minWidth in a global way?
Thanks</p>
