How to define a shape.xml for RadioButton?
<p>I want to create a custom drawable for RadioButton's button drawable.</p>

<p>I have created a theme and style, which points the RadioButton's button drawable to a custom drawable defined in XML.</p>

<p>The drawable.xml looks like this:</p>

<pre><code>&lt;android:shape xmlns:android="http://schemas.android.com/apk/res/android" shape="oval"&gt;
  &lt;android:solid color="#ffffffff"/&gt;
&lt;/android:shape&gt;
</code></pre>

<p>But this displays a blank area where the button should have been.</p>

<p>I tried adding a size parameter as well:</p>

<pre><code>&lt;android:shape xmlns:android="http://schemas.android.com/apk/res/android" shape="oval"&gt;
  &lt;android:solid color="#ffffffff"/&gt;
  &lt;android:size width="16dip" height="16dip" /&gt;
&lt;/android:shape&gt;
</code></pre>

<p>But no luck with that either.</p>
