Создайте класс, который реализует провайдера, например:

FloatingSearchView floatingSearchView = new FloatingSearchView(this, null, sColorSuggestions);

try {
    String[] coloursArray = getElement().getStringArray();
    List<String> coloursList = Arrays.asList(coloursArray);
    coloursNameList = new ArrayList<>();

    if (!coloursList.isEmpty()) {
        for (String currentItem : coloursList) {
            currentItem = currentItem.substring(currentItem.indexOf("+") + 1);
            currentItem = currentItem.substring(0, currentItem.indexOf("+"));
            coloursNameList.add(currentItem);
        }
    }
} catch (IOException | NotExistException | WrongTypeException e) {
    LogUtil.error(TAG, "Произошло исключение - " + e.getMessage());
}

FloatingSearchView.init(SUGGESTION_COUNT, new FloatingSearchView.OnSuggestionClickListener() {
    @Override
    public void onSuggestionClick(String alert) {
        int textLength = alert.length();
        ArrayList<String> tempArrayList = new ArrayList<>();
        for (String currentItem : coloursNameList) {
            if (textLength <= coloursNameList.size()) {
                if (currentItem.toLowerCase(Locale.getDefault()).contains(alert.toLowerCase(Locale.getDefault()))) {
                    tempArrayList.add(currentItem);
                }
            }
        }
    }
});
