切换拇指可以在选择器中的state_enabled设置

Question

我正在用自己的拇指和轨道进行自定义开关。我想要的是，在我的拇指XML中，在检查状态下设置了不同的颜色，并且在禁用开关时，还设置了不同的颜色。问题在于，当我将state_enabled设置为false，Nothind发生时，只有检查状态起作用时，为什么会发生这种情况？

<?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>

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_enabled="true" android:state_selected="true">
<shape android:shape = "oval">
         <size android:width = "24dp" android:height="24dp"/>
         <solid android:color="@color/green"/>
      </shape>
    </item>

<item android:state_enabled="true" android:state_selected="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>
