FireBase Realtime Datasebase ist in der zweiten Ansicht leer

Ich habe Probleme mit einem Fragment, das eine Listview mit Elementen einer Firebase Realtime Database über einen Adapter zeigt. Wenn ich das Fragment zum ersten Mal öffne, zeigt es alles, wie es sein sollte, aber wenn ich zu einem anderen Fragment gehe und das erste Fragment zum zweiten Mal öffne, bleibt es leer. Es ist wie im Bild unten gezeigt.FireBase Realtime Datasebase ist in der zweiten Ansicht leer

Problem with empty fragment

Hier ist mein Code:

Tablayout Fragment:

public class Stand_Fragment extends Fragment { 

DatabaseReference mDatabase; 
Toolbar toolbar; 
TabLayout tabLayout; 
ViewPager viewPager; 
Stand_ViewPager standViewPager; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View View = inflater.inflate(R.layout.fragment_stand, container, false); 

    getActivity().setTitle("Stand"); 

    tabLayout = (TabLayout)View.findViewById(R.id.tabLayout_stand); 
    viewPager = (ViewPager) View.findViewById(R.id.viewPager_stand); 

    toolbar = (Toolbar) View.findViewById(R.id.toolbar_stand); 
    ((AppCompatActivity)getActivity()).setSupportActionBar(toolbar); 

    tabLayout = (TabLayout)View.findViewById(R.id.tabLayout_stand); 
    viewPager = (ViewPager) View.findViewById(R.id.viewPager_stand); 
    standViewPager = new Stand_ViewPager(getFragmentManager()); 
    standViewPager.addFragments(new StandBeker_Fragment(), "Beker"); 
    standViewPager.addFragments(new StandCompetitie_Fragment(), "Competitie"); 
    standViewPager.addFragments(new StandBeker_Fragment_Admin(), "Admin Beker"); 
    standViewPager.addFragments(new StandCompetitie_Fragment_Admin(), "Admin Competitie"); 

    tabLayout.setTabTextColors(ColorStateList.valueOf(Color.parseColor("#ffffff"))); 
    viewPager.setAdapter(standViewPager); 
    tabLayout.setupWithViewPager(viewPager); 

    return View; 
} 
}

Fragment der Listenansicht zeigt:

public class StandBeker_Fragment extends Fragment { 

private DatabaseReference mDatabaseRef; 
private List<ImageUpload> imgList; 
private ListView lv; 
private StandBeker_Adapter adapter; 
private ProgressDialog progressDialog; 

public StandBeker_Fragment(){ 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    final View View = inflater.inflate(R.layout.activity_image_list, container, false); 

    imgList = new ArrayList<>(); 
    lv = (ListView) View.findViewById(R.id.ListViewImage); 

    progressDialog = new ProgressDialog(getActivity()); 
    progressDialog.setMessage("Aan het laden..."); 
    progressDialog.show(); 

    mDatabaseRef = FirebaseDatabase.getInstance().getReference(StandBeker_Fragment_Admin.FB_DATABASE_PATH); 
    mDatabaseRef.addValueEventListener(new ValueEventListener() { 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      progressDialog.dismiss(); 

      for(DataSnapshot snapshot : dataSnapshot.getChildren()) { 
       ImageUpload img = snapshot.getValue(ImageUpload.class); 
         imgList.add(img); 
      } 
      adapter = new StandBeker_Adapter(getActivity(), R.layout.fragment_stand_beker, imgList); 
      lv.setAdapter(adapter); 
     } 

     @Override 
     public void onCancelled(DatabaseError databaseError) { 
     } 
    }); 

    return View; 
} 
}

Adapter Klasse der Listenansicht:

public class StandBeker_Adapter extends ArrayAdapter<ImageUpload> { 
private Activity context; 
private int resource; 
private List<ImageUpload> listImage; 

public StandBeker_Adapter(@NonNull Activity context, @LayoutRes int resource, @NonNull List<ImageUpload> objects) { 
    super(context, resource, objects); 
    this.context = context; 
    this.resource = resource; 
    listImage = objects; 
} 

@NonNull 
@Override 
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) { 
    LayoutInflater inflater = context.getLayoutInflater(); 

    View v = inflater.inflate(resource, null); 
    TextView tvName = (TextView) v.findViewById(R.id.tvImageName); 
    ImageView img = (ImageView) v.findViewById(R.id.imgView); 

    tvName.setText(listImage.get(position).getName()); 
    Glide.with(context).load(listImage.get(position).getUrl()).into(img); 

    return v; 
} 
}

Wird in Ihrem Logcat beim Wechseln der Registerkarten etwas Verdächtiges angezeigt? –

Sind das die Protokolle, die beim Wechseln der Tabs auftreten? Ich bin interessiert zu sehen, was in Logcat gedruckt wird, wenn Sie auf Ihrem Tab zum zweiten Mal drücken (und nichts wird angezeigt). Sie scheinen die Daten von Firebase korrekt zu lesen (wie Sie es zum ersten Mal sehen) und ich denke, dass Ihr Problem entweder durch den Adapter oder durch den Tab-Fragment-Code –

Verschieben Sie den Code zum Abrufen von Daten aus Firebase von der onCreateView-Methode zu onResume() Methode.

@Override 
public void onResume() { 
    super.onResume(); 

    progressDialog = new ProgressDialog(getActivity()); 
    progressDialog.setMessage("Aan het laden..."); 
    progressDialog.show(); 

    mDatabaseRef = FirebaseDatabase.getInstance().getReference(StandBeker_Fragment_Admin.FB_DATABASE_PATH); 
    mDatabaseRef.addValueEventListener(new ValueEventListener() { 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      progressDialog.dismiss(); 

      for(DataSnapshot snapshot : dataSnapshot.getChildren()) { 
       ImageUpload img = snapshot.getValue(ImageUpload.class); 
         imgList.add(img); 
      } 
      adapter = new StandBeker_Adapter(getActivity(), R.layout.fragment_stand_beker, imgList); 
      lv.setAdapter(adapter); 
     } 

     @Override 
     public void onCancelled(DatabaseError databaseError) { 
     } 
    });

Vielen Dank für Ihre Antwort. Ich dachte daran (und ich habe es gerade noch einmal ausprobiert), aber leider löst das das Problem nicht. – kelseyvdheijden

Fügen Sie einen Haltepunkt in der 'onCreateView()' hinzu und debuggen Sie die App. Prüfen Sie, ob die Methode aufgerufen wird. –
