DisplayListCanvas viene avviato su RenderNode non vincolato (senza mOwningView)

Question

Sto tentando di popolare AutoCompleteTextView utilizzando la mia personalizzata ArrayAdapter. Penso che funzioni bene con l'aggiunta di valori di visualizzazione. L'unico problema è che non viene visualizzato alcun menu a discesa. Qualcuno sa come avere questo dropdown visibile? Ogni volta che dovrebbe vedere la discesa posso vedere log dei messaggi dicendo:

DisplayListCanvas: DisplayListCanvas è stato avviato sul RenderNode unbinded (senza mOwningView)

Il mio codice adattatore:

public class UserSearchAdapter extends ArrayAdapter<Profile> { 

    Context context; 
    ArrayList profiles; 


    public UserSearchAdapter(Context context, int resource, ArrayList<Profile> objects) { 
     super(context, resource, objects); 
     this.context = context; 
     this.profiles = objects; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     if (convertView == null) { 
      convertView = LayoutInflater.from(this.getContext()) 
        .inflate(R.layout.single_user_item, parent, false); 
     } 

     Profile profile = (Profile) profiles.get(position); 

     TextView text = (TextView) convertView.findViewById(R.id.single_user_name_text); 
     text.setText(profile.getDisplayName()); 

     return convertView; 
    } 

} 

Il mio codice MainActivity:

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_member_supervisor); 
    activity = MemberSupervisorActivity.this; 

    Firebase.setAndroidContext(this); 

    autoCompleteUser = (AutoCompleteTextView) findViewById(R.id.auto_members); 

    profiles = new ArrayList<>(); 

    members = new UserSearchAdapter(activity, R.layout.single_user_item, profiles); 

    autoCompleteUser.setAdapter(members); 
    autoCompleteUser.setThreshold(1); 

    autoCompleteUser.addTextChangedListener(new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, int count, int after) { 

     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, int before, int count) { 

     } 

     @Override 
     public void afterTextChanged(Editable s) { 
      final Query auto = new Firebase(Constants.FIREBASE_USER_PROFILE).orderByChild("displayName").startAt(autoCompleteUser.getText().toString()).endAt(autoCompleteUser.getText().toString() + "~"); 
      auto.addListenerForSingleValueEvent(new ValueEventListener() { 
       @Override 
       public void onDataChange(DataSnapshot dataSnapshot) { 
        profiles.clear(); 
        Log.d("entered", autoCompleteUser.getText().toString()); 
        for (DataSnapshot data : dataSnapshot.getChildren()) { 
         Profile profile = data.getValue(Profile.class); 
         profiles.add(profile); 
         Log.d("results", profile.getDisplayName()); 
        } 
        members.notifyDataSetChanged(); 
       } 

       @Override 
       public void onCancelled(FirebaseError firebaseError) { 

       } 
      }); 
     } 
    }); 

}

Modificare l'adattatore che ha la logica di filtraggio al suo interno come mostrato di seguito.

public class UserSearchAdapter extends ArrayAdapter<Profile> { 

    Context context; 
    ArrayList profiles; 
    ArrayList<Profile> suggestions, tempItems; 

    public UserSearchAdapter(Context context, int resource, ArrayList<Profile> objects) { 
     super(context, resource, objects); 
     this.context = context; 
     this.profiles = objects; 
     this.suggestions=new ArrayList(); 
     tempItems = new ArrayList(Profile); 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     if (convertView == null) { 
      convertView = LayoutInflater.from(this.getContext()) 
        .inflate(R.layout.single_user_item, parent, false); 
     } 

     Profile profile = (Profile) profiles.get(position); 

     TextView text = (TextView) convertView.findViewById(R.id.single_user_name_text); 
     text.setText(profile.getDisplayName()); 

     return convertView; 
    } 

    @Override 
    public Filter getFilter() { 
     return nameFilter; 
    } 

    /** 
    * Custom Filter implementation for custom suggestions we provide. 
    */ 
    Filter nameFilter = new Filter() { 
     @Override 
     public CharSequence convertResultToString(Object resultValue) { 
      String str = ((Profile) resultValue).getName(); 
      return str; 
     } 

     @Override 
     protected FilterResults performFiltering(CharSequence constraint) { 
      if (constraint != null) { 
       suggestions.clear(); 
       for (Profile profile : tempItems) { 
        if (profile.getDisplayName().toLowerCase().contains(constraint.toString().toLowerCase())) { 
         suggestions.add(profile); 
        } 
       } 
       FilterResults filterResults = new FilterResults(); 
       filterResults.values = suggestions; 
       filterResults.count = suggestions.size(); 
       return filterResults; 
      } else { 
       return new FilterResults(); 
      } 
     } 

     @Override 
     protected void publishResults(CharSequence constraint, FilterResults results) { 
      List<Profile> filterList = (ArrayList<Profile>) results.values; 
      if (results != null && results.count > 0) { 
       clear(); 
       for (Profile profile : filterList) { 
        add(profile); 
        notifyDataSetChanged(); 
       } 
      } 
     } 
    }; 
} 

Nota: import android.widget.Filter; Spero che questo aiuti !!!
