You can use AutoCompleteTextView. Described in http://developer.android.com/guide/topics/ui/controls/text.html.
Probably Custom adapter will help you to make two suggestions lists. Take a look at this Autocompletetextview with custom adapter and filter. I guess you need to create divider in custom adapter.
As described in comments. Just Make listview visible when you need to show suggestions. Or paste in eclipse and remove android:visibility="gone" attribute and you will see gray listview over textviews.
