Android Google Places API - PlaceAutocompleteFragment clear button listener

Looking at the source code of PlaceAutocompleteFragment I found those view ids and setup a onClickListener like this:

autocompleteFragment.getView().findViewById(R.id.place_autocomplete_clear_button)
    .setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // example : way to access view from PlaceAutoCompleteFragment
            // ((EditText) autocompleteFragment.getView()
            // .findViewById(R.id.place_autocomplete_search_input)).setText(""); 
            autocompleteFragment.setText("");
            view.setVisibility(View.GONE);
        }
});
