Suchansicht in benutzerdefinierten ArrayAdapter

Question

Ich habe eine benutzerdefinierte 'ArrayAdapter' in einer 'ListView', mein Problem ist ein Menü 'SearchView'. Es funktioniert nicht richtig. Ich weiß nicht, ob das Problem die Ergebnisse sucht oder zeigt, weil nichts erscheint. Und wenn möglich, möchte ich eine benutzerdefinierte Liste der Ergebnisse anzeigen. Vielen Dank!

Fragment mit dem Adapter

ArrayList<Favoritos> favorites; 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 

    View rootView = inflater.inflate(R.layout.list_item, container, false); 
    favorites = new ArrayList<Favoritos>(); 
    favorites.add(new Favorites("Title", "addres", 5, false, 7, 22, 4.5f)); 
    favorites.add(new Favorites("Title", "addres", 3.5 , true, 7, 22, 3.0f)); 
    favorites.add(new Favorites("Title", "addres", 2, false, 7, 22, 4.0f)); 
    favorites.add(new Favorites("Titleo", "addres", 4.5, true, 7, 22, 5.0f)); 

    FavoritesAdapter adapter = new FavoritesAdapter(getActivity(), favorites); 

    ListView listView = (ListView) rootView.findViewById(R.id.list_item); 

    listView.setAdapter(adapter); 
} 


@Override 
public boolean onQueryTextSubmit(String s) { 
    return false; 
} 

@Override 
public boolean onQueryTextChange(String string) { 
    search(string); 
    return true; 
} 

//This is the search method 
public void search(String s) { 
    if (s == null || s.trim().equals("")) { 
     cleanSearch(); //In this method I just "reset" the adapter when the user "give up" 
     return; 
    } 

    ArrayList<Favoritos> estacionamentosEncontrados = new ArrayList<Favoritos>(favoritos); 

    for (int i = estacionamentosEncontrados.size() - 1; i >= 0; i--) { 
     Favoritos estacionamento = estacionamentosEncontrados.get(i); 
     Favoritos nenhumResultado = new Favoritos("Nenhum resultado encontrado"); 
     if (!estacionamento.mIndicacao.toUpperCase().contains(s.toUpperCase())) { 
      estacionamentosEncontrados.remove(estacionamento); 
     } else { 
      estacionamentosEncontrados.add(nenhumResultado); 
     } 
    } 

    adapter = new EncontradosAdapter(getActivity(), estacionamentosEncontrados); 
    ListView listView = (ListView) getActivity().findViewById(R.id.list_item); 
    listView.setAdapter(adapter); 
} 

Favorites.java

Schritt: 1 Erstellen Sie im Optionsmenü in Fragmente für anbraten chview wie

@Override 
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
     super.onCreateOptionsMenu(menu, inflater); 
     //menu.clear(); 
     inflater.inflate(R.menu.ticket_fragment_search_menu, menu); 
     MenuItem actionSearch = menu.findItem(R.id.action_search); 

     SearchView searchView = (SearchView) MenuItemCompat.getActionView(actionSearch); 
     searchView.setMaxWidth(Integer.MAX_VALUE); 
     EditText searchEditText = (EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text); 
     searchEditText.setSingleLine(true); 
     searchEditText.setTextColor(getResources().getColor(R.color.black)); 
     searchEditText.setHintTextColor(getResources().getColor(R.color.black)); 
     searchView.setQueryHint(getResources().getString(R.string.txt_search_here)); 
     searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() { 
      @Override 
      public boolean onQueryTextSubmit(String query) { 
       return false; 
      } 

      @Override 
      public boolean onQueryTextChange(String newText) { 
       //apply Filter 
       adapter.setFilter(newText) 
       return false; 
      } 
     }); 

     searchView.setOnSearchClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Log.e(TAG, "search open"); 
      } 
     }); 

     searchView.setOnCloseListener(new SearchView.OnCloseListener() { 
      @Override 
      public boolean onClose() { 
       Log.e(TAG, "search close"); 
       return false; 
      } 
     }); 

    } 

Schritt 2: Funktion für Filter erstellen oder

in Adapter suchen

public void setFilter(String str) { 
     aList = new ArrayList<>(); 
     if (aListTemp.size() > 0) { 
      for (int i = 0; i < aListTemp.size(); i++) { 
       if (aListTemp.get(i).toLowerCase().contains(str.toLowerCase()) 
         ) { 

        aList.add(aListTemp.get(i)); 
       } 
      } 
     } 
     notifyDataSetChanged(); 
    }
