Android SearchView не работает во фрагменте

Question

Я пытаюсь реализовать поиск, который требуется только в одном фрагменте. Он будет фильтроваться в списке.

public class SalesParts extends Fragment { 

public SalesParts() { 
    // Required empty public constructor 
} 
ArrayList<ListViewsModel> listofOrderSelectedArray = new ArrayList<ListViewsModel>(); 
ArrayList<ListViewsModel> listofOrdersArray = new ArrayList<ListViewsModel>(); 
SimpleAdapter adapter; 
ArrayAdapter arrayAdapter2; 
ListView mListView; 
ArrayList<HashMap<String, Object>> items; 


@Override 
public void onActivityCreated(Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 

    listofOrdersArray.add(new ListViewsModel(101, "Order Title 1","")); 
    listofOrdersArray.add(new ListViewsModel(102, "Order Title 2","")); 
    listofOrdersArray.add(new ListViewsModel(103, "Order Title 3","")); 
    listofOrdersArray.add(new ListViewsModel(104, "Order Title 4","")); 
    listofOrdersArray.add(new ListViewsModel(105, "Order Title 5",""));

    listofOrdersArray.add(new ListViewsModel(108, "Order Title 8","")); 
    listofOrdersArray.add(new ListViewsModel(109, "Order Title 9","")); 
    listofOrdersArray.add(new ListViewsModel(110, "SOrder Title 10","")); 

    mListView = (ListView) getActivity().findViewById(R.id.salespartsList); 
    mListView.setTextFilterEnabled(true); 

    SearchView mSearchView = (SearchView) getActivity().findViewById(R.id.typeFindSalesPart); 
    mSearchView.setIconifiedByDefault(false); 
    mSearchView.setOnQueryTextListener(this); 
    mSearchView.setSubmitButtonEnabled(false); 


    items = new ArrayList<HashMap<String, Object>>(); 
    HashMap<String, Object> listItem; 

    for (int i = 0; i < listofOrdersArray.size(); i++) { 
     ListViewsModel selectedDescription = listofOrdersArray.get(i); 
     listItem = new HashMap<String, Object>(); 
     listItem.put("itemTitle",selectedDescription.itemTitle); 
     listItem.put("itemID",selectedDescription.itemId); 
     listItem.put("addBtn", ""); 
     items.add(listItem); 
    } 

    ListView addSelectedItems = (ListView) getActivity().findViewById(R.id.salespartsListSelected); 
    arrayAdapter2 = new ArrayAdapter(getActivity(),R.layout.selected_salespart_item,R.id.itemTitle, listofOrderSelectedArray) { 

     @Override 
     public View getView(final int position, View convertView, ViewGroup parent) { 
      View view = super.getView(position, convertView, parent); 

      // get filled view from SimpleAdapter 
      View itemView = super.getView(position, convertView, parent); 
      // find our button there 
      View addButton = itemView.findViewById(R.id.itemDeleteBtn); 

      // set a tag to get button position in array (used to get values when button is clicked 
      addButton.setTag(String.valueOf(position)); 

      // add an onClickListener 
      addButton.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        String tagName = (String) v.getTag(); 
        int arrayPosition = Integer.valueOf(tagName); 

        //remove selected item from the list of sales parts to choose from 
        listofOrderSelectedArray.remove(arrayPosition); 
        arrayAdapter2.notifyDataSetChanged(); 
       } 
      }); 

      return itemView; 
     } 
    }; 
    addSelectedItems.setAdapter(arrayAdapter2); 

    adapter = new SimpleAdapter(getActivity(), items, R.layout.salespart_item, new String[]{"itemTitle", "addBtn"}, new int[]{R.id.itemTitle, R.id.itemAddBtn}) { 

     @Override 
     public View getView(final int position, View convertView, ViewGroup parent) { 
      View view = super.getView(position, convertView, parent); 

      // get filled view from SimpleAdapter 
      View itemView = super.getView(position, convertView, parent); 
      // find our button there 
      View addButton = itemView.findViewById(R.id.itemAddBtn); 

      // set a tag to get button position in array (used to get values when button is clicked 
      addButton.setTag(String.valueOf(position)); 

      // add an onClickListener 
      addButton.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        String tagName = (String) v.getTag(); 
        int arrayPosition = Integer.valueOf(tagName); 
        String title =listofOrdersArray.get(arrayPosition).itemTitle; 
        int id =listofOrdersArray.get(arrayPosition).itemId; 

        // add selected item to list of selected sales parts 
        listofOrderSelectedArray.add(new ListViewsModel(id, title, "")); 
        arrayAdapter2.notifyDataSetChanged(); 
       } 
      }); 

      return itemView; 
     } 
    }; 
    mListView.setAdapter(adapter); 

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    return inflater.inflate(R.layout.fragment_sales_parts, container, false); 
} 
} 

Я разместил код выше в «OnActivityCreated» я получаю ошибку на setOnQueryTextListener (это) линии. Я попытался изменить «this» на getActivity() и getView(), и ни одна из них не разрешила проблему.

Answer 1

Изменение onCreateView(...) как

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
        Bundle savedInstanceState) { 
// Inflate the layout for this fragment 
View view=inflater.inflate(R.layout.fragment_sales_parts, container, false); 

    mListView = (ListView)view.findViewById(R.id.salespartsList); 

    SearchView mSearchView = (SearchView)view.findViewById(R.id.typeFindSalesPart); 

    ........... 
return view; 
} 

и удалить весь код из onActivityCreated(....) и перейти к onCreateView(....)

Answer 2

Почему бы не использовать SearchView как ниже вместе с фильтром для ListView, как в ссылке Android SearchView Filter ListView

searchView.setOnQueryTextListener(new OnQueryTextListener() { 
     @Override 
     public boolean onQueryTextSubmit(String arg0) { 
     // filter listview 
      return true; 
     } 

     @Override 
     public boolean onQueryTextChange(String arg0) { 

      return false; 
     } 
    });
