Android Google Places API - PlaceAutocompleteFragment clear button listener

Question

I am using Google Places API for Android - PlaceAutocompleteFragment API in my project to search locations, when user selects a location then get the records using location la

Answer 1

I create the findViewById in the onCreate of the activity, I was getting the following error

java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.View android.view.View.findViewById(int)' on a null object reference

Because the fragment is not initialized/visible yet. I moved the listener inside the setOnPlaceSelectedListener and it's working fine now.

autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
    @Override
    public void onPlaceSelected(Place place) {
        homeAddressPlaceID = place.getId();
        Log.i(TAG, "Place: " + place.getName() + ", " + place);

        autocompleteFragment.getView().findViewById(R.id.places_autocomplete_clear_button)
                .setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        autocompleteFragment.setText("");
                        homeAddressPlaceID = "";
                    }
                });
    }

    @Override
    public void onError(Status status) {
        Log.i(TAG, "An error occurred: " + status);
    }
});
