Why are styles not included for popupMenu?

Question

Android

Help solve the problem. I want to create a popup-menu with a dark background and a white font color. But the user style is not connected for some reason to the menu.
styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@null</item>
        <item name="popupMenuStyle">@style/AppTheme.darkPopupStyle</item>
    </style>

    <style name="AppTheme.darkPopupStyle" parent="Widget.AppCompat.PopupMenu">
        <item name="android:itemBackground">@drawable/popup_drawable</item>
        <item name="android:textColor">@android:color/white</item>
    </style>

</resources>

popup_drawable.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <color
            android:color="@android:color/darker_gray"/>
    </item>
    <item>
        <color
            android:color="@android:color/black"/>
    </item>
</selector>

The code where I create a menu object and connect styles to it:

ContextWrapper wrapper = new ContextThemeWrapper(context, R.style.AppTheme_darkPopupStyle);
                PopupMenu menu = new PopupMenu(wrapper, v);

Use android.support.v7.widget.PopupMenu
Help solve the problem. Thanks in advance for your help.
