Been stuck here for a bit, I've tried to used the Firebase UI FirebaseRecyclerAdapter, but it wont take multiple references for the keys generated by the GeoQuery. So i used a typical Array adapter. The problem is that whenever the object is updated/changed in Firebase, it creates duplicates of the object in the array. I've tried to use if(!arrayofcars.contains(car)), but it doesn't change as technically the objects are different. Here's a bit of the code..
GeoFire geoFire = new GeoFire(mDatabaseReference.child("cars_location"));
GeoQuery geoQuery = geoFire.queryAtLocation(new GeoLocation(userLat, userLong), 20);
geoQuery.addGeoQueryEventListener(new GeoQueryEventListener() {
#Override
public void onKeyEntered(String key, GeoLocation location) {
Toast.makeText(CarHopActivity.this, "Key: " + key, Toast.LENGTH_SHORT).show();
tempDataRef = FirebaseDatabase.getInstance().getReference("/cars/" + key);
tempDataRef.addChildEventListener(new ChildEventListener() {
#Override
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
Car car = dataSnapshot.getValue(Car.class);
Log.d(TAG, "this is the object"+ car.getCarName());
arrayOfCars.add(car);
nearestCars.notifyDataSetChanged();
}
#Override
public void onChildChanged(DataSnapshot dataSnapshot, String s) {
}
#Override
public void onChildRemoved(DataSnapshot dataSnapshot) {
}
#Override
public void onChildMoved(DataSnapshot dataSnapshot, String s) {
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
and here is the Object class...
public class Car {
private String carName;
private int carCount;
private int carCap;
private String carAddress;
private String carPhotoURI;
private String userId;
public double getLatitude() {
return latitude;
}
public void setLatitude(double latitude) {
this.latitude = latitude;
}

this.longitude = longitude;

this.userId = userId;

How can i get branch Choix from Sondage and print it into my Adapter class.
Here's my ModelClass

}
}
Inside my main class, I retreive my data successfully, but i can't get the branch Choix to print it

If anyone can help, I would be so grateful, i'm suck in this for 2 days.
I hope you are well. I am trying to add text to a text view from a document in Firestore. I was told you cant query a document by id withing a collection group, so I created a field "id" with the documentID and queried that, but still nothing and no errors.
Here is my activity:
public class FoodItemPage extends AppCompatActivity {
private FirebaseFirestore db = FirebaseFirestore.getInstance();
ElegantNumberButton number_button;
Button addtocart;
TextView food_name, food_description;
EditText extra_notes;
String foodId;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_food_item_page);
foodId = getIntent().getStringExtra("foodid");
//firestore
Query singlefoodref = db.collectionGroup("Foods").whereEqualTo("id", foodId);
Log.d(TAG, "well hello there" + foodId);
//init view
number_button = (ElegantNumberButton) findViewById(R.id.number_button);
addtocart = (Button) findViewById(R.id.addToCart);
food_name = (TextView) findViewById(R.id.food_name1);
food_description = (TextView) findViewById(R.id.food_description);
singlefoodref.get().addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
#Override
public void onSuccess(QuerySnapshot queryDocumentSnapshots) {
if (queryDocumentSnapshots.isEmpty()){
Toast.makeText(FoodItemPage.this, "document not there", Toast.LENGTH_SHORT);
Log.d(TAG, "NOT WORKING");
}else{
FoodModel foodModel = queryDocumentSnapshots.getDocuments().get(0).toObject(FoodModel.class);
food_name.setText(foodModel.getName());
Log.d(TAG, "WORKING");
}
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(FoodItemPage.this, "Error", Toast.LENGTH_SHORT);
}
});
}
}
My model (i am also using the same Model in another activity, that shouldn't be a problem right?) :
package com.example.hostapp.Models;
public class FoodModel {
private String name;
private String description;
private String image;
private String price;
private String discount;
private String categoryid;
public FoodModel() {
}
public FoodModel(String name, String description, String image, String price, String discount, String categoryid) {
this.name = name;
this.description = description;
this.image = image;
this.price = price;
this.discount = discount;
this.categoryid = categoryid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public String getDiscount() {
return discount;
}
public void setDiscount(String discount) {
this.discount = discount;
}
public String getCategoryid() {
return categoryid;
}
public void setCategoryid(String categoryid) {
this.categoryid = categoryid;
}
}
Edit:
My database structure, each restaurant has its own "Foods" collections with the food items i am trying to load.
SO I fixed this, the error was in my database, the id in the database had a space in it so it wasn't matching the document ID from the previous activity.
so from " 123456" to "123456"
The location that a user retrieves from Firebase for a specific post is always coming back as the same erroneous location, always the same one. I have tried various alternatives for this code trying to work it around so that the specific location that user created for their event saved to the GoogleMap comes back, but keep getting same location for all posts and it's incorrect.
I've been using a few other posts with location problems on here, but haven't helped me.
Please tell me what I am doing wrong.

You didn't set your model correctly. Update your Post like below:
Post.java:
public class Post {
private String postid;
private String postimage;
private String description;
private String publisher;
private String text_event;
private String text_location;
private String text_date_time;
private Long timestamp;
private MyLocation location;
//getter-setter
}
MyLocation.java:
public class MyLocation {
private double latitude;
private double longitude;
public double getLatitude() {
return latitude;
}
public void setLatitude(double latitude) {
this.latitude = latitude;
}
public double getLongitude() {
return longitude;
}
public void setLongitude(double longitude) {
this.longitude = longitude;
}
}
And then parse like
Post post = snapshot.getValue(Post.class);
double latitude = post.getLocation().getLatitude();
double longitude = post.getLocation().getLongitude();
I have a problem running this part of my application, I am using a recyclerwiew with its adapter inside this activity, but this error occurs:
Can not convert object of type java.lang.String to type.
I have used this same code many times and it always worked for me, I do not know what happens.
Part of problem:
homeModelList = new ArrayList<>();
mDatabaseRef = FirebaseDatabase.getInstance().getReference("Listas").child(post.getLid());
Toast.makeText(ProductListActivity.this, post.getLid(), Toast.LENGTH_SHORT).show();
mDatabaseRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
homeModelList.clear();
for (DataSnapshot snapshot : dataSnapshot.getChildren()){
HomeModel homeModel = snapshot.getValue(HomeModel.class);
if (post.getLid().equals(post.getUidL())){
homeModelList.add(homeModel);
}
}
mAdapter = new ProductoAdapter(getApplicationContext(), homeModelList);
recycler_viewLista.setAdapter(mAdapter);
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
Class:
import java.io.Serializable;
public class HomeModel implements Serializable {
private String Titulo;
private String Uid;
private String Lid;
private String Producto;
private Integer Cantidad;
private String UidL;
public HomeModel() {
}
public HomeModel(String titulo, String uid, String lid, String producto, Integer cantidad, String uidL) {
Titulo = titulo;
Uid = uid;
Lid = lid;
Producto = producto;
Cantidad = cantidad;
UidL = uidL;
}
public String getTitulo() {
return Titulo;
}
public void setTitulo(String titulo) {
Titulo = titulo;
}
public String getUid() {
return Uid;
}
public void setUid(String uid) {
Uid = uid;
}
public String getLid() {
return Lid;
}
public void setLid(String lid) {
Lid = lid;
}
public String getProducto() {
return Producto;
}
public void setProducto(String producto) {
Producto = producto;
}
public Integer getCantidad() {
return Cantidad;
}
public void setCantidad(Integer cantidad) {
Cantidad = cantidad;
}
public String getUidL() {
return UidL;
}
public void setUidL(String uidL) {
UidL = uidL;
}
}
Change the following:
public void onDataChange(DataSnapshot dataSnapshot) {
homeModelList.clear();
for (DataSnapshot snapshot : dataSnapshot.getChildren()){
HomeModel homeModel = snapshot.getValue(HomeModel.class);
if (post.getLid().equals(post.getUidL())){
homeModelList.add(homeModel);
}
}
into this:
public void onDataChange(DataSnapshot dataSnapshot) {
homeModelList.clear();
HomeModel homeModel = dataSnapshot.getValue(HomeModel.class);
if (post.getLid().equals(post.getUidL())){
homeModelList.add(homeModel);
}

Haven't read if much, but i first noticed something here.
for(DataSnapshot ds :dataSnapshot.getChildren()){
if(ds.getKey().equals(context.getString(R.string.dbname_car_post))){
try{ }
The key you're trying to retrieve is an Object. So i would propose we convert it string first, sample down here.
for(DataSnapshot ds :dataSnapshot.getChildren()){
Object myKey=ds.getKey;
if(myKey.toString().equals(context.getString(R.string.dbname_car_post))){
try{ }
}}
Let me know what happens next!
