title: Multiple layouts recyclerView with data coming from firebase
body: <p>I'm trying to get data from Firestore and add them to a recycler view, I tried doing this:</p>
  
  <pre><code>for (DocumentChange doc : queryDocumentSnapshots.getDocumentChanges()) {
      if (doc.getType() == DocumentChange.Type.ADDED) {
  
          Users users = doc.getDocument().toObject(Users.class);
  
          if (users.getName() != null) {                
              if(users.getStatus() == null){                    
                  mUsersList.add(new Users(true));
                  mUsersList.add(users);                    
              }
  
              mUsersList.add(users);
              usersListAdapter.notifyDataSetChanged();
          }
      }
  }
  </code></pre>
  
  <p>I have an adapter already configured in the proper way, but when I try setting the Boolean flag, that is required for showing one layout or the other this appears:</p>
  
  <blockquote>
    <p>java.lang.RuntimeException: Could not deserialize object. Class com.example.gusta.client.list_model.Users does not define a no-argument constructor. If you are using ProGuard, make sure these constructors are not stripped.</p>
  </blockquote>
  
  <p>This I because I need an empty constructor for this, but if I set an empty constructor on my List, I wont be able to choose between the layouts.</p>
  
  <p>If you know the answer or knows a video class that could help me solving this problem I would be very glad, thanks.</p>
