Switch thumb can't set state_enabled in selector-CodePudding

I'm making a custom switch with my own thumb and track. What I want is, in my thumb xml, set a different color in checked state, unchecked state and also, set a different color when the switch is disabled. The problem is that when I set state_enabled to false, nothind happen, just checked states works, why is this happening?

<?xml version="1.0" encoding ="utf-8"?>
<selector xmlns:android.....>
   <item android:state_checked = "true">
      <shape android:shape = "oval">
         <size android:width = "24dp" android:height="24dp"/>
         <solid android:color="@color/green"/>
      </shape>
   </item>

   <item android:state_checked="false">
      <shape android:shape="oval">
          <size android:width = "24dp" android:height="24dp"/>
          <solid android:color="@color/red"/>
      </shape>
   </item>
   <item android:state_enabled="false">
       <shape android:shape="oval">
          <size android:width = "24dp" android:height="24dp"/>
          <solid android:color="@color/black"/>
       </shape>
   </item>
</selector>
