java.lang.IllegalStateException: Obiekt nie jest już zarządzany przez Realm. Czy został usunięty?

Question

Ja uczę się królestwa i Recyclerview. Zrobiłem prostą aplikację, w której można łatwo dodawać elementy i usuwać je. Wszystko działa poprawnie, dopóki nie zacznę usuwać elementu jeden po drugim. Na ostatniej pozycji po kliknięciu usunąć to daje mi wyjątek

java.lang.IllegalStateException: Object is no longer managed by Realm. Has it been deleted? 

To jest mój kod

@Override 
    public void onDeleteClick(int position) { 
     mRealm.beginTransaction(); 
     mResult.get(position).deleteFromRealm(); 
     mRealm.commitTransaction(); 
     adapter.notifyItemRemoved(position); 
    } 

Oto całego stosu

Answer 1

Ok dzięki Christian Melchior o pomoc. Poprawiłem mój kod, wykonując tę ​​

Przed

@Override 
    public void onBindViewHolder(MyListViewHolder holder, int position) { 
      Persons p = persons.get(position); 
      holder.firstName.setText(p.getFirstName()); 
      holder.lastName.setText(p.getLastName()); 
    } 

Po

@Override 
    public void onBindViewHolder(MyListViewHolder holder, int position) { 

     if (persons.get(position).isValid()) { 
      Persons p = persons.get(position); 
      holder.firstName.setText(p.getFirstName()); 
      holder.lastName.setText(p.getLastName()); 
     } 
    }
