How to set dropdown background for transparent in AutoCompoteTextView in Android?

Question

As the subject suggests, how to set a transparent background in the AutoCompleteTextView drop-down list. I can apply any style to the view (TextView) that appears in the drop-down list, but in order to make the picture itself transparent, I can not do it!
