title: Customize divider / separator in dropdown of an AutocompleteTextview
body: <p>I've seen this question asked some other times on the site, but no one couldn't get any answer.</p>
  
  <p>Is there any way to customize the appearance of the divider in the dropdown showing when using an AutocompleteTextview in android?</p>
  
  <p>It's pretty easy for a ListView, but using only an ArrayAdapter for the autocompletetextview, is there any way to customize the divider.</p>
  
  <p>(Not the textview, I already know doing that)</p>
