MultiAutoCompleteTextView is an editable text view, extending AutoCompleteTextView, that can show completion suggestions for the substring of the text where the user is typing instead of necessarily for the entire thing.

You must must provide a MultiAutoCompleteTextView.Tokenizer to distinguish the various substrings.



It can be comapred with "Example of AutoCompleteTextView".
