ImageButton Tint选择器不是根据状态更改颜色

Question

我想根据button状态更改image button图标颜色色调。它与通用按钮的背景合作，但对于imageButton图标，它根本不起作用。即使我禁用它，它仍然处于“启用”状态。

<style name="newbutton.iconified">
    <item name="android:layout_width">@dimen/button_height</item>
    <item name="android:layout_height">@dimen/button_height</item>
    <item name="android:minHeight">0dp</item>
    <item name="android:minWidth">0dp</item>
    <item name="android:paddingStart">@dimen/small_padding_start</item>
    <item name="android:paddingEnd">@dimen/small_padding_end</item>
    <item name="android:paddingTop">@dimen/small_padding_top</item>
    <item name="android:paddingBottom">@dimen/small_padding_bottom</item>
    <item name="android:background">@null</item>
    <item name="android:tint">@color/buttons_button_iconified</item>
</style>

buttons_button_iconified.xml

<selector
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:exitFadeDuration="200"
    android:enterFadeDuration="200">
    <item
        android:state_enabled="false"
        android:alpha="0.4"
        android:color="@color/button_primary"
        />
    <item
        android:state_pressed="true"
        android:alpha="0.4"
        android:color="@color/button_primary"
        />
    <item
        android:alpha="1"
        android:color="@color/button_primary"/>
</selector>
