I'm retrieving data from firebase and trying to display that in recycler view, every thing is fine but it only shows one item in the list (there are total 14 items)
comment if you do not understand the question
This is my main activity where i get datasnapshots from firebase
public class cakes_activity extends AppCompatActivity {
RecyclerView recyclerView;
ArrayList<Data> listdata;
private DatabaseReference mref;
private NorthAdaptor north;
private final Context context = this;
public int counter = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cakes);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
EditText editText = (EditText) findViewById(R.id.editText) ;
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
//FIREBASE
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mref= FirebaseDatabase.getInstance().getReference("Cakes");
mref.addChildEventListener(new ChildEventListener() {
#Override
public void onChildAdded(DataSnapshot dataSnapshot, String s) {
Data data = dataSnapshot.getValue(Data.class);
listdata = new ArrayList<>();
listdata.add(data);
north = new NorthAdaptor(context,listdata);
recyclerView.setLayoutManager(new LinearLayoutManager(context));
recyclerView.hasFixedSize();
recyclerView.setAdapter(north);
}
#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 the following code is my adaptor class:
public class NorthAdaptor extends RecyclerView.Adapter<NorthAdaptor.NorthHolder> {
private LayoutInflater inflater;
ArrayList<Data> northy;
public NorthAdaptor(Context context,ArrayList<Data> northy)
{
inflater=LayoutInflater.from(context);
this.northy=northy;
}
public NorthHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.each_item,parent,false);
NorthHolder holder = new NorthHolder(view);
return holder;
}
#Override
public void onBindViewHolder(NorthHolder holder, int position) {
holder.text2.setText(northy.get(position).getName());
holder.text3.setText("₹."+northy.get(position).getRS());
}
#Override
public int getItemCount() {
return northy.size();
}
class NorthHolder extends RecyclerView.ViewHolder implements View.OnClickListener
{
TextView text,text2,text3;
ImageView img;
private final Context context;
public NorthHolder(View itemview)
{
super(itemview);
context = itemView.getContext();
CardView card = (CardView) itemView.findViewById(R.id.card);
text3=(TextView)itemView.findViewById(R.id.Rs);
text2 = (TextView) itemView.findViewById(R.id.itemtext2);
img = (ImageView) itemView.findViewById(R.id.itemimage);
card.setOnClickListener(this);
}
#Override
public void onClick(View view){
Toast.makeText(
cakes_activity.this,
"Your message here",
Toast.LENGTH_SHORT
).show();
}
}
}
this is my java class to store the data received from firebase
public class Data {
private String ID,Name,image,RS;
public Data(){
}
public Data(String ID, String Name, String image, String RS) {
this.ID = ID;
this.Name = Name;
this.image= image;
this.RS = RS;
}
public String getId() {
return ID;
}
public String getRS() {
return RS;
}
public void setId(String id) {
this.ID = id;
}
public String getName() {
return Name;
}
public void setName(String Name) {
this.Name = Name;
}
public String getimage() {
return image;
}
public void setImg(String image) {
this.image = image;
}
}
listdata = new ArrayList<>();
north = new NorthAdaptor(context,listdata);
recyclerView.setLayoutManager(new LinearLayoutManager(context));
recyclerView.hasFixedSize();
recyclerView.setAdapter(north);
you need to write this code in onCreate instead of onchildadded

i have facing issue like only two items are displayed others two items are not displayed they are contact and flat no this items are not displaying...i tried also removing and adding others textview but through this only two items are displayed.... Now I want to display the data on a RecyclerView which doesn't seem to work, I'm pretty sure that my code is good but something doesn't seem to work and I can't find it.i also try all the things suggested by stackoverflow but nothing can happen so that i think i need to ask...

I'm still relatively new to Android and firebase and trying to populate recyclerview from firebase database but for some reasons that I can't get, the view is not populated.The activity loads but all I see is a blank activity page.I'd like to populate these views using data from a Firebase Database just to get three data(name,email,phonenos) of Users.
public class TestUsersActivity extends AppCompatActivity {
public TextView mname,email,phone;
private RecyclerView recyclerView;
FirebaseAuth mAuth;
DatabaseReference mDatabase;
private FirebaseRecyclerAdapter adapter;
private LinearLayoutManager linearLayoutManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test_users);
recyclerView = findViewById(R.id.listuser);
mDatabase = FirebaseDatabase.getInstance().getReference().child("Users");
linearLayoutManager = new LinearLayoutManager(getApplicationContext());
linearLayoutManager.setReverseLayout(true);
linearLayoutManager.setStackFromEnd(true);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(linearLayoutManager);
fetch();
}
private void fetch() {
FirebaseRecyclerOptions<Users> options = new FirebaseRecyclerOptions.Builder<Users>()
.setQuery(mDatabase,Users.class)
.build();
adapter = new FirebaseRecyclerAdapter<Users, ViewHolder>(options) {
#Override
protected void onBindViewHolder(#NonNull ViewHolder myViewHolder, int i, #NonNull Users users) {
myViewHolder.setName(users.getFname() + " "+ users.getLname());
myViewHolder.setEmail(users.getEmail());
myViewHolder.setphone(users.getPhonenos());
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.user_list_row,parent, false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
#Override
public void onDataChanged() {
super.onDataChanged();
}
};
recyclerView.setAdapter(adapter);
adapter.startListening();
}
#Override
protected void onStop() {
super.onStop();
adapter.stopListening();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public ViewHolder(View itemView) {
super(itemView);
mname = itemView.findViewById(R.id.name);
email = itemView.findViewById(R.id.email);
phone = itemView.findViewById(R.id.phoneNos);
}
public void setName(String string) {
mname.setText(string);
}
public void setEmail(String string) {
email.setText(string);
}
public void setphone(String string){
phone.setText(string);
}
}
}
Below is my modelclass that i want to get just the name,email and phone nos from.
public class Users {
private String fname;
private String lname;
private String email;
private String phonenos;
private String jobTitle;
private String dateCreated;
private String lastlogin;
public Users(){
}
public Users(String fname, String lname, String email, String phonenos, String jobTitle, String dateCreated, String lastlogin) {
this.fname = fname;
this.lname = lname;
this.email = email;
this.phonenos = phonenos;
this.jobTitle = jobTitle;
this.dateCreated = dateCreated;
this.lastlogin = lastlogin;
}
public String getFname() {
return fname;
}
public void setFname(String fname) {
this.fname = fname;
}
public String getLname() {
return lname;
}
public void setLname(String lname) {
this.lname = lname;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhonenos() {
return phonenos;
}
public void setPhonenos(String phonenos) {
this.phonenos = phonenos;
}
public String getJobTitle() {
return jobTitle;
}
public void setJobTitle(String jobTitle) {
this.jobTitle = jobTitle;
}
public String getDateCreated() {
return dateCreated;
}
public void setDateCreated(String dateCreated) {
this.dateCreated = dateCreated;
}
public String getLastlogin() {
return lastlogin;
}
public void setLastlogin(String lastlogin) {
this.lastlogin = lastlogin;
}
}
I don't know if you must pass a query instead of a database reference
make the query a member variable
......
private Query query;
......
do this:
query = FirebaseDatabase.getInstance().getReference().child("Users");
and pass it like this to options
FirebaseRecyclerOptions<Users> options = new FirebaseRecyclerOptions.Builder<Users>()
.setQuery(query,Users.class)
.build();
ALSO MAKE SURE YOUR FIREBASE SECURITY RULES ARE NOT SET TO READ FALSE

I guess your problem is by the way you refer to your data so instead of this
databaseReference = FirebaseDatabase.getInstance().getReference("order");
use this
databaseReference = FirebaseDatabase.getInstance().getReference().child("order");
and you didn't use a query object to query your database reference
so now you don't query directly from databaseReference like the way you did it
instead you do this:
Query query=databaseReference.orderByChild("phone").equalTo(phone);
once you have a query that fits you now add on child listener and continue the rest of your code:
query.addChildEventListener(new ChildEventListener() {
//the rest of your code goes here(on child added/changed/......)
)};
