Customize divider / separator in dropdown of an AutocompleteTextview

Question

I've seen this question asked some other times on the site, but no one couldn't get any answer.

Is there any way to customize the appearance of the divider in the dropdown showing when using an AutocompleteTextview in android?

It's pretty easy for a ListView, but using only an ArrayAdapter for the autocompletetextview, is there any way to customize the divider.

(Not the textview, I already know doing that)

Im not sure how you can do it for single AutoCompleteTextView but I know how to set it for the whole application. This should also help you :)

<style name="MyTheme" parent="AppTheme">
        <item name="android:dropDownListViewStyle">@style/MyListViewStyle</item>
</style>

<style name="MyListViewStyle" parent="@android:style/Widget.ListView">
        <item name="android:divider">#F00</item>
        <item name="android:dividerHeight">1px</item>
</style>
