I recently started learning about Firebase.

Adding data to the firebase is successful but I face problems while retrieving the
data from the firebase.

My **MainActivity.java** is as follows:

```
public class MainActivityFragment extends Fragment {

TextView time_stamp;

public MainActivityFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
final View rootView=inflater.inflate(R.layout.fragment_main, container,
false);
    final TextView owner=(TextView)rootView.findViewById(R.id.owner);
    time_stamp=(TextView)rootView.findViewById(R.id.time_stamp_textView);
    final TextView changed_data_view=(TextView)rootView.findViewById(R.id.changedView);

    Firebase mRef=new Firebase(Constants.FirebaseUrl).child("activeList");
    mRef.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {

        POJOS pojos=new POJOS();
            changed_data_view.setText(pojos.getListname());
           Log.i("LIST",pojos.getListname());
            Log.i("OWNER",pojos.getOwner());

            owner.setText(pojos.getOwner());

        }

        @Override
        public void onCancelled(FirebaseError firebaseError) {

        }
    });

    return rootView;
  }
}

```

My POJO class is as follows :

```
public class POJOS {

public  String  listname;
public  String owner;

public POJOS() {
}

public POJOS(String listname, String owner) {
    this.listname = listname;
    this.owner = owner;
}

 public  String getListname(){
   return listname;
}

  public  String getOwner() {
    return owner;
  }

}

```

My Add item class is as follows :

```
public  class Dialog extends DialogFragment {

private final String title="ADD AN ITEM";
private EditText editText;
Button addButton;

public Dialog(){

}

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
getDialog().setTitle(title);
    View rootView=inflater.inflate(R.layout.dialog_box,null);

    editText=(EditText)rootView.findViewById(R.id.editText);
    addButton=(Button) rootView.findViewById(R.id.addButton);
    addButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String userEnteredName=editText.getText().toString();
            Firebase firebase=new Firebase(Constants.FirebaseUrl);
            POJOS pojos =new POJOS(userEnteredName,"ANONYMOUS USER");

            firebase.child("activeList").setValue(pojos);

            dismiss();

        }
    });

    return rootView;
}

}

```

The pojos.getListname() and pojos.getOwner() are always null.

Please provide a solution to my problem.

Thanks in advance !
