title: Android AutoCompleteTextView suggestion if nothing is found
body: <p>I am making a point of sale app for Android, and I have a AutoCompleteTextView loaded in with the database of items that they can buy, but I also want the AutoCompleteTextView to double as a way to add custom items/notes into the order.</p>
  
  <p>So for example, the customer is ordering Steak, but doesnt want any seasoning. My database includes options for 'No Onions' 'No Mushrooms', etc, but not 'No Seasoning', and if the waiter types in 'No Seasoning' into the AutoCompleteTextView, I want a suggestion 'Add as Note' to pop up.</p>
  
  <p>Is there a way to add this suggestion when no other suggestions are found, either by making it always on the dropdown list (making it not able to be filtered out), or by detecting when no items are on the dropdown list and adding it in then?</p>
