AutoComplete for Xamarin.Android: Completion modes

RadAutoCompleteTextView has two modes for filtering suggestions.

  • StartsWith
  • Contains

The completion mode can be changed with the CompletionMode property of the AutoCompleteTextView's adapter (of type AutoCompleteAdapter). The default value is CompletionMode.StartsWith.

this.adapter.CompletionMode = CompletionMode.StartsWith;

StartsWith Mode

In CompletionMode.StartsWith mode the autocomplete shows only suggestions that start with the typed phrase.


Contains Mode

In CompletionMode.Contains mode the autocomplete shows only suggestions that contain the typed phrase.

Contains Mode is not intended to work with the APPEND and SUGGEST_APPEND modes. Since both these modes append the rest of the suggestion to the typed text, the combination between these modes won't be helpful, it will be rather confusing.
