How to define a circle shape in an Android xml dra

Question

I have some problems finding the documentation of the definitions of shapes in XML for Android. I would like to define a simple circle filled with a solid color in an XML File to include it into my layout files.

Sadly the Documentation on android.com does not cover the XML attributes of the Shape classes. I think I should use an ArcShape to draw a circle but there is no explanation on how to set the size, the color, or the angle needed to make a circle out of an Arc.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/text_color_green"/>
            <!-- Set the same value for both width and height to get a circular shape -->
            <size android:width="250dp" android:height="250dp"/>
        </shape>
    </item>
</selector>
