Understanding Background Changes When Selecting PopupMenu

For background changes when selecting PopupMenu, apply "listselector_popup.xml" to the style
I want to make it happen.
As it is, "@color/dialog_background_color
Only ' ' applies, but 'listselector_popup.xml' does not apply when selected.
*The background color is gray, which is close to black, but when selected, it is light gray on Android 4.4.4 and black on Android 8.
I don't feel any change when I use Android 8, so I want to specify it myself.

Even if the source is corrected by referring to the answer below, there is no change.

        <item name="android:dropDownSelector">@drawable/listselector_popup</item>
        <item name="android:listViewStyle">@style/CustomListView2</item>
    </style>
    <style name="CustomListView2" parent="@android:style/Widget.ListView">
        <item name="android:listSelector">@drawable/listselector_popup</item>

We were able to:
PopupMenu is defined in item, and it's itemBackground.

styles.xml
    <!--Pop-up Theme-->
    <style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
        <item name="android:textColor">@color/font_color</item>
        <item name="android:colorBackground">@color/dialog_background_color</item>
        <item name="android:itemBackground">@drawable/listselector_popup</item>
    </style>
