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.

Answer 1

If you want a circle like this

Try using the code below:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="ring"
android:thicknessRatio="2"
android:useLevel="false" >
<solid android:color="@android:color/white" />
<stroke
    android:width="1dp"
    android:color="@android:color/darker_gray" /></shape>

Answer 2

You can try this -

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="ring"
    android:innerRadiusRatio="700"
    android:thickness="100dp"
    android:useLevel="false">

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

</shape>

Also, you can adjust the radius of the circle by adjusting android:thickness.

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>

Answer 4

I couldn't draw a circle inside my ConstraintLayout for some reason, I just couldn't use any of the answers above.

What did work perfectly is a simple TextView with the text that comes out, when you press "Alt+7":

 <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#0075bc"
            android:textSize="40dp"
            android:text="•"></TextView>
