RecyclerView Firebase UI

Grünschnabel
Hey Leute,
ich habe versucht ein Messenger zu programmieren wo man bei einen Punk talle Benutzer die die App hat sehen kann. Der Code dazu sieht so aus:
Java:
public class AllUserActivity extends AppCompatActivity {


Toolbar mToolbar;
RecyclerView recyclerView;
private DatabaseReference mUserDatabse;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_all_user);


mToolbar = (Toolbar) findViewById(R.id.usersappbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setTitle("Alle Benutzer");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);

mUserDatabse = FirebaseDatabase.getInstance().getReference().child("Users");

recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));

}

@Override
protected void onStart() {
super.onStart();

FirebaseRecyclerAdapter<User, UsersViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<User, UsersViewHolder>(User.class, R.layout.users_single_layout, UsersViewHolder.class, mUserDatabse) {
@Override
protected void populateViewHolder(UsersViewHolder viewHolder, User model, int position) {
viewHolder.setName(model.getName());
}
};

firebaseRecyclerAdapter.startListening();
recyclerView.setAdapter(firebaseRecyclerAdapter);
User Activity:

Java:
public class User {

public String name;
public String Image;
public String status;

public User(){

}

public User(String name, String image, String status) {
this.name = name;
Image = image;
this.status = status;
}

public String getName() {

return name;
}

public void setName(String name) {
this.name = name;
}

public String getImage() {
return Image;
}

public void setImage(String image) {
Image = image;
}

public String getStatus() {
return status;
}

public void setStatus(String status) {
this.status = status;
}
}
}

public static class UsersViewHolder extends RecyclerView.ViewHolder {

View mView;

public UsersViewHolder(@NonNull View itemView) {
super(itemView);

mView = itemView;
}

public void setName(String name){

TextView userNameView = (TextView) mView.findViewById(R.id.username_tv);
userNameView.setText(name);
}


}

}
Mein problem ist das überhapt kein Benutzer im RecyclerView angezeigt wird. KAnn mir da vllt jemand helfen?
