如何解码GeoFire生成的GeoHash？

Question

我是Android开发的新手，将非常感谢任何指导。我想知道在将坐标保存到Firebase时是否有一种方法可以解码GeoFire生成的GeoHash。我看不到来自GeoFire的服务，这些服务只能解码坐标以获取纬度或经度。如果有一个图书馆，请告诉我，我被困在一个项目中，进行了大量研究，但还没有找到任何有价值的东西。再次感谢！

DatabaseReference mUser;
GeoFire geoFire;
FirebaseUser mFirebase;

Marker mCurrent;
Circle mPerimeter;
SupportMapFragment mapFragment;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    // SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
    mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);


    //Init View

    //-------AUTHENTICATION--------------
    FirebaseAuth mAuth = FirebaseAuth.getInstance();
    String userID;
    userID = mAuth.getCurrentUser().getUid();

    startLocationUpdates();
    displayLocation();
    Snackbar.make(mapFragment.getView(), "You are online",Snackbar.LENGTH_SHORT)
            .show(); 

    //--------SEND COORDINATES TO FIREBASE-------------
    mUser = FirebaseDatabase.getInstance().getReference().child("Location");

    geoFire =new GeoFire(mUser);
