Witam,
(pisze na laptopie nie obslugujacym polskich znakow)
Pisze aplikacje ktora m.in. ma czytac osoby ktore obserwuje uzytkownik. Calosc jest podpieta pod Firebase. Niestety w moim ListView nie pojawiaja sie dane pobierane z Database. Kiedy wchodze w aktywnosc w ktorej mam obejrzec osoby ktore obserwuje, niestety widze tylko biala przestrzen i nic poza tym. Logcat nic nie pokazuje. W zwiazku z tym nie wiem czy wina lezy w wyciaganiu danych z FirebaseDatabase czy w przenoszeniu ich adapterem na ListView. Prosze o pomoc:)

FollowingFragment.java


public class FollowingFragment extends AppCompatActivity{

    private ListView mListView;
    TextView username;
    CircleImageView profilePhoto;
    private Context mContext;
    List<FollowingRow> followingList;
    DatabaseReference databaseFollowing;



    @Nullable

    public void onCreateView(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_following);
        mContext = this;
        mListView = (ListView) findViewById(R.id.listView1);

        databaseFollowing = FirebaseDatabase.getInstance().getReference("following").child("user_id");

        followingList = new ArrayList<>();
        getIncomingIntent();

        databaseFollowing.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                followingList.clear();

                for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {

                    FollowingRow following = postSnapshot.getValue(FollowingRow.class);
                    followingList.add(following);
                }
                FollowingList adapter = new FollowingList(FollowingFragment.this, followingList);
                mListView.setAdapter(adapter);
            }

            @Override
            public void onCancelled(DatabaseError databaseError) {

            }
        });


    }

    private void getIncomingIntent(){
        Intent intent = getIntent();

    }

}

FollowingList.java

public class FollowingList extends ArrayAdapter<FollowingRow> {

    private Activity context;
    List<FollowingRow> followingList;

    public FollowingList(Activity context, List<FollowingRow> followingList) {

        super(context, R.layout.layout_followrow, followingList);
        this.context = context;
        this.followingList = followingList;

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = context.getLayoutInflater();
        View listViewItem = inflater.inflate(R.layout.layout_followrow, null, true);
        TextView username = (TextView) listViewItem.findViewById(R.id.following_username2);
     //   ImageView followingPhoto = (ImageView) listViewItem.findViewById(R.id.following_profile_image2);


        FollowingRow fRow = followingList.get(position);
        username.setText(fRow.getfName());


        return listViewItem;

    }


}

FollowingRow.java

public class FollowingRow {


        //private String comment;
        private String user_id;
        private String fName;

     //   private List<Like> likes;
       // private String date_created;

        public FollowingRow() {

        }

        public FollowingRow( String user_id, String fName) {

            this.user_id = user_id;
            this.fName = fName;

          }



        public String getUser_id() {
            return user_id;
        }

         public String getfName() {
        return fName;
        }

    public void setUser_id(String user_id) {
            this.user_id = user_id;
        }

        @Override
        public String toString() {
            return "FollowingRow{" +
                    " user_id='" + user_id + '\'' + '}';
        }
    }
