How to set inner radius on circle shape in drawable programatically in Android?
<p>I have an xml drawable:</p>

<pre><code>&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="@dimen/button_numpad_size"
android:thicknessRatio="1"
android:shape="ring"
android:useLevel="false" &gt;
</code></pre>

<p>How do I change innerRadius through code and then refresh it?</p>
