Как реализовать плавное расположение в пользовательском интерфейсе базы данных адаптера Firebase Recycler?

У меня проблема с реализацией объединенного местоположения, какой метод используется для получения текущего местоположения устройства в пользовательском интерфейсе базы данных Firebase, но он не работает, потому что была красная линия, которая заметила

Cannot resolve method 'addOnSuccessListener(anonymous com.firebase.ui.database.FirebaseRecyclerAdapter<co.id.roningrum.dolanapptugasakhir.item.CategoryItem,co.id.roningrum.dolanapptugasakhir.adapter.CategoryViewHolder>, anonymous com.google.android.gms.tasks.OnSuccessListener<android.location.Location>)

Есть три класса, которые я уже сделал, CategoryItem, CategoryViewHolder и CategoryMenuActivity.CategoryItem - это класс модели, CategoryViewHolder - это класс ViewHolder, а CategoryMenuActivity - это класс активности, который используется для отображения списка элементов.

  1. CategoryItem.java 

public class CategoryItem {
    private String name_tourism;
    private String location_tourism;
    private String info_tourism;
    private String telepon;
    private String url_photo;
    private double lat_location_tourism;
    private double lng_location_tourism;

    public CategoryItem() {
        //constructor untuk panggilan ke DataSnapshot.getValue
    }

    public CategoryItem(String name_tourism, String location_tourism, String info_tourism, String telepon, String url_photo, double lat_location_tourism, double lng_location_tourism) {
        this.name_tourism = name_tourism;
        this.location_tourism = location_tourism;
        this.info_tourism = info_tourism;
        this.telepon = telepon;
        this.url_photo = url_photo;
        this.lat_location_tourism = lat_location_tourism;
        this.lng_location_tourism = lng_location_tourism;
    }

    public String getName_tourism() {
        return name_tourism;
    }

    public void setName_tourism(String name_tourism) {
        this.name_tourism = name_tourism;
    }

    public String getLocation_tourism() {
        return location_tourism;
    }

    public void setLocation_tourism(String location_tourism) {
        this.location_tourism = location_tourism;
    }

    public String getInfo_tourism() {
        return info_tourism;
    }

    public void setInfo_tourism(String info_tourism) {
        this.info_tourism = info_tourism;
    }

    public String getTelepon() {
        return telepon;
    }

    public void setTelepon(String telepon) {
        this.telepon = telepon;
    }

    public String getUrl_photo() {
        return url_photo;
    }

    public void setUrl_photo(String url_photo) {
        this.url_photo = url_photo;
    }

    public double getLat_location_tourism() {
        return lat_location_tourism;
    }

    public void setLat_location_tourism(double lat_location_tourism) {
        this.lat_location_tourism = lat_location_tourism;
    }

    public double getLng_location_tourism() {
        return lng_location_tourism;
    }

    public void setLng_location_tourism(double lng_location_tourism) {
        this.lng_location_tourism = lng_location_tourism;
    }
}

        loc2.setLatitude(categoryItem.getLat_location_tourism());
        loc2.setLongitude(categoryItem.getLng_location_tourism());

        float jarakMeter = loc1.distanceTo(loc2);
        float jarakKM = jarakMeter/1000;

        DecimalFormat df = new DecimalFormat();
        df.setMaximumFractionDigits(2);

Это мои данные структуры базы данных Firebase Realtime Structure Database

Я ожидаю, что метод слияния местоположения может работатьпотому что мое ожидание показать расстояние, которое является результатом расчета расстояния между текущим местоположением и местом назначения.Спасибо :) 1026 *
