如何在SearchView中更改文本后刷新ListView

Question

当前，我的代码中没有错误，但是每当我在ListView中搜索一个项目时，它都可以正常工作，但是当我后退/删除SearchView中的输入时，它不会刷新。我该如何编码此刷新部分？

就像我每次在SearchView中键入或删除内容一样，它实际上应该通过在ListView中显示适当的结果来不断刷新我的搜索。例如，如果我完全删除SearchView中的输入，它将显示所有可用的结果（当前，我的不会刷新）

AuctionListAdapter.java：

public class AuctionListAdapter extends BaseAdapter implements Filterable {

    ValueFilter valueFilter;


    private Context context;
    private int layout;
    private ArrayList<Model> auctionList;





    public AuctionListAdapter(Context context, int layout, ArrayList<Model> auctionList) {
        this.context = context;
        this.layout = layout;
        this.auctionList = auctionList;

    }

    @Override
    public int getCount() {
        return auctionList.size();
    }

    @Override
    public Object getItem(int position) {
        return auctionList.get(position);
    }


    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public Filter getFilter() {
        if (valueFilter == null) {
            valueFilter = new ValueFilter();
        }
        return valueFilter;
    }

    private class ValueFilter extends Filter {
        @Override
        protected FilterResults performFiltering(CharSequence constraint) {
            FilterResults results = new FilterResults();

            if (constraint != null && constraint.length() > 0) {
                ArrayList<Model> filterList = new ArrayList<Model>();
                for (int i = 0; i < auctionList.size(); i++) {
                    if ((auctionList.get(i).getName().toUpperCase())
                            .contains(constraint.toString().toUpperCase())||(auctionList.get(i).getDescription().toUpperCase())
                            .contains(constraint.toString().toUpperCase())||(auctionList.get(i).getPrice().toUpperCase())
                            .contains(constraint.toString().toUpperCase())||(auctionList.get(i).getDuration().toUpperCase())
                            .contains(constraint.toString().toUpperCase())) {
                        Model model = new Model(auctionList.get(i).getId(),auctionList.get(i).getName(),
                                auctionList.get(i).getDescription(),auctionList.get(i).getPrice(),auctionList.get(i).getDuration()
                                ,auctionList.get(i).getImage());
                        filterList.add(model);


                    }
                }
                results.count = filterList.size();
                results.values = filterList;
            } else {
                results.count = auctionList.size();
                results.values = auctionList;
            }
            return results;

        }


        @Override
        protected void publishResults(CharSequence constraint,
                                      FilterResults results) {
            auctionList = (ArrayList<Model>) results.values;

            notifyDataSetChanged();

        }




    }
}

AuctionList.java：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.searchmenu,menu);

    MenuItem myActionMenuItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView)myActionMenuItem.getActionView();

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String text) {

            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            mAdapter.getFilter().filter(newText);
            return false;
        }
    });


    return super.onCreateOptionsMenu(menu);
}
