How to create ring shape drawable in android?

2dp outer ring with a 2dp gap:

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">    <item        android:top="4dp"        android:right="4dp"        android:bottom="4dp"        android:left="4dp">        <shape            android:shape="oval">            <solid android:color="#4d4d4d" />        </shape>    </item>    <item>        <shape            android:shape="oval">            <stroke android:width="2dp"                android:color="#4d4d4d"/>        </shape>    </item></layer-list>

You will need to create a drawable and set it as a background.

shape_primary_ring.xml

<shape    xmlns:android="http://schemas.android.com/apk/res/android"    android:innerRadiusRatio="2.5"    android:shape="ring"    android:thickness="4dp"    android:useLevel="false">    <solid android:color="@color/colorPrimary"/></shape>

Preview

Ring drawable is juxtaposition of elements, use layer-list

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">  <item android:right="6dip" android:left="6dip">    <shape xmlns:android="http://schemas.android.com/apk/res/android"           android:innerRadius="0dp"           android:shape="ring"           android:thicknessRatio="3"           android:useLevel="false" >      <solid android:color="@android:color/transparent" />      <stroke          android:width="5dp"          android:color="@color/maroon" />    </shape>  </item>  <item android:right="20dip"        android:left="20dip"        android:bottom="0dip"        android:top="34dip">    <shape xmlns:android="http://schemas.android.com/apk/res/android"           android:shape="rectangle"           android:innerRadius="0dp">      <solid android:color="@color/maroon" />      <stroke android:width="1dip" android:color="@android:color/transparent" />    </shape>  </item>  <item android:right="20dip"        android:left="20dip"        android:bottom="34dip"        android:top="0dip">    <shape xmlns:android="http://schemas.android.com/apk/res/android"           android:shape="rectangle"           android:innerRadius="0dp">      <solid android:color="@color/maroon" />      <stroke android:width="1dip" android:color="@android:color/transparent" />    </shape>  </item></layer-list>

Xml drawable by all means more useful than static images, they can be correctly scaled without need of .9 library or generating set of different sizes from Gimp, Photoshop
