How to define a circle shape in an Android xml drawable file?


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.

This is a simple circle as a drawable in Android.

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

   <solid 
       android:color="#666666"/>

   <size 
       android:width="120dp"
        android:height="120dp"/>
</shape>

Set this as your view background

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <stroke
        android:width="1dp"
        android:color="#78d9ff"/>
</shape>

enter image description here

For solid circle use:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid
        android:color="#48b3ff"/>
</shape>

enter image description here

Solid with stroke:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#199fff"/>
    <stroke
        android:width="2dp"
        android:color="#444444"/>
</shape>

enter image description here

Note: To make the oval shape appear as a circle, in these examples, either your view that you are using this shape as its background should be a square or you have to set the height and width properties of the shape tag to an equal value.
