Resource ID not found for attribute 'alpha' in package 'android.support.design'

Question

I created a library project from

android-sdk\extras\android\m2repository\com\android\support\design\design-25.0.1.aar

I added libraries appcompat, recyclerviewand cardview.

An error message appears:

design_25.0.1 \ res \ color \ design_tint_password_toggle.xml: 19: error: Resource ID not found for attribute 'alpha' in package 'android.support.design'

This is the code design_tint_password_toggle.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:app="http://schemas.android.com/apk/res-auto">
    <item android:state_checked="true" android:color="?android:attr/colorForeground" app:alpha="0.54"/>
    <item android:color="?android:attr/colorForeground" app:alpha="0.38"/>
</selector>

How can I fix this error?
