xml - android how to change <item> width and height

Question

I'm making a <layer-list> for drawable.

I have my background image, and I want the second layer to be smaller, but it seems that doesn't matter what I'm writing inside my android:layer_width and android:layer_height.

The second layer size is still the same.

Here is my xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <item
        android:drawable="@drawable/picuser" 
        android:layout_width="50dp"
        android:layout_height="50dp" />

    <item
        android:drawable="@drawable/ic_launcher" 
        android:layout_width="10dp"
        android:layout_height="10dp" />
</layer-list>

This is kind of a workaround, but it worked for me.
You can use padding in order to make the second drawable smaller.

<item android:drawable="@drawable/circyle" />

<item
    android:drawable="@drawable/plus" 
    android:top="10dp"
    android:bottom="10dp"
    android:right="10dp"
    android:left="10dp" />
