How to set drawable size in layer-list

You can use android:width and android:height parameters with desired values.

Below is the sample drawable layer-list and screen shot. I used the vector drawable from google material icons and own selector drawable.

Original circle.xml drawable shape have 100dp x 100dp size, but into drawable.xml I override this values to 24dp x 24dp by android:width and android:height parameters.

I hope this help!

drawable.xml

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">    <item android:drawable="@drawable/circle" android:height="24dp" android:width="24dp"/>    <item android:drawable="@drawable/ic_accessibility_black_24dp"/>    <item android:drawable="@drawable/ic_http_white_24dp" android:gravity="center" android:top="-3dp" android:height="5dp" android:width="5dp"/></layer-list>

circle.xml

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item>        <shape android:innerRadius="20dp" android:shape="oval">            <solid android:color="#CCC" />            <size android:width="100dp" android:height="100dp"/>        </shape>    </item></selector>

You can use inset tag for this.For example

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">   <item android:drawable="@drawable/menu_drawable1"/>   <item>       <inset android:drawable="@drawable/menu_drawable2"           android:insetRight="50dp"           android:insetTop="50dp"           android:insetLeft="50dp"           android:insetBottom="50dp" />   </item>

This will create paddings around you menu_drawable2 so it won`t be scaled. Just set the dimensions that you require.

I also came across the issue on Android 5.0 (API 21). It seems the gravity of item doesn't work for API less than 23. So the layout is required to be updated, I've made it compatible by applying calculated paddings for the second item node which is supposed to be a right-top aligned overlay.

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">    <item android:drawable="@drawable/ic_svg_filter_black"/>    <item        android:left="16dp"        android:right="0dp"        android:top="0dp"        android:bottom="16dp"        android:drawable="@drawable/ic_circle_dot_red"    /></layer-list>
