Using a State Selector for Nested Drawables

I am relatively new to using a selector for modifying properties for states such as enabled/disabled, etc. I have learned to use them for direct properties (such as textColor, background, etc.) in the layout files (such as activity_main.xml) & in styles (in styles.xml), but for things such as nested drawables I am not quite sure what to do. For example, I have a Button whose background is a layer-list drawable, and one of the drawables in that layer-list is a VectorDrawable, which has a path whose fillColor I need to change based on the enabled state of my Button. How do I do this?

    I'm not sure what I was doing wrong before or why I didn't think it would work (I'm still very new to drawables & selectors), but here it is now and it works:


    <?xml version="1.0" encoding="utf-8" ?>  
    <layer-list xmlns:android="">  
    		<shape android:shape="rectangle">  
    			<solid android:color="@color/Silver"/>  
    			<stroke android:width="2dp" android:color="@color/Black"/>  
    			<corners android:radius="0dp"/>  
    	<item android:gravity="fill" android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp">  
    		<vector android:width="30dp" android:height="30dp" android:viewportWidth="30" android:viewportHeight="30">  
    			<path android:pathData="M0 0L30 0L15 30Z" android:fillColor="@drawable/incdecbuttonarrowcolorselector"/>  

    <?xml version="1.0" encoding="utf-8" ?>
    <selector xmlns:android="">
    <item android:state_enabled="true" android:color="@Color /Black"/>
    <item android:state_enabled="false" android:color="@Color /Gray"/>
