Android滤清器回收站查看来自翻新的数据

我有这个回收站视图，并且我从Retrofit API获取数据，问题是当我尝试在回收站中进行过滤时，我在互联网上搜索并且所有示例都是字符串列表，但是我有对象列表，如何解决这个问题案例并在工具栏中创建过滤器？我将发布我的代码，并希望任何人提供帮助，谢谢

活动

public class TodoList extends AppCompatActivity implements DialogFragUpdateListener {
    RecyclerView todoRecyclerView;
    private RecyclerView.Adapter todoAdapter;
    private RecyclerView.LayoutManager todoLayoutManager;
    public List<ToDo> results;
    public List<String> list = new ArrayList<>();


    TodoRecyclerAdapter recyclerAdapter;
    Context context;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_todo_list);


        todoRecyclerView = (RecyclerView)findViewById(R.id.todoRecyclerView);
        todoRecyclerView.setHasFixedSize(true);
        results= new ArrayList<ToDo>();


        todoLayoutManager = new LinearLayoutManager(this);
        todoRecyclerView.setLayoutManager(todoLayoutManager);

       
        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {

                Intent intent = new Intent(TodoList.this,AddToDo.class);
                startActivity(intent);
            }
        });}

    public void getRetrofitObject() {
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())

                results = response.body().getResults();
                if(recyclerAdapter == null){

                recyclerAdapter = new TodoRecyclerAdapter(this,results);
                todoRecyclerView.setAdapter(recyclerAdapter);
            }
            else{

                recyclerAdapter.setData(results);
                recyclerAdapter.notifyDataSetChanged();
            }

            }
            @Override
            public void onFailure(Call<Result> call, Throwable t) {
                Log.d("onFailure", t.toString());
            }});}

    @Override
    public void OnDBUpdate() {


        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)

                results = response.body().getResults();
                if(recyclerAdapter == null){

                recyclerAdapter = new TodoRecyclerAdapter(this,results);
                todoRecyclerView.setAdapter(recyclerAdapter);
            }
            else{

                recyclerAdapter.setData(results);
                recyclerAdapter.notifyDataSetChanged();
            }
            }
            @Override
            public void onFailure(Call<Result> call, Throwable t) {
                Log.d("onFailure", t.toString());
            }});
    }




    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_search, menu);
        MenuItem searchItem = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
        searchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {

            @Override
            public void onFocusChange(View v, boolean hasFocus) {

            }
        });

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

            @Override
            public boolean onQueryTextSubmit(String query) {
recyclerAdapter.getFilter().filter(query);
                return false;
            }

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

        MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() {
            @Override
            public boolean onMenuItemActionCollapse(MenuItem item) {
                return true;
            }
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) {
                return true;
            }
        });
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();

        if (id == R.id.action_search) {

            return true;
        }
        return super.onOptionsItemSelected(item);
    }}

这是适配器

public class TodoRecyclerAdapter  extends RecyclerView.Adapter<TodoRecyclerAdapter.ViewHolder>  {
static List<ToDo> todoResults;
static Context context;
List<ToDo>results;
ArrayList<ToDo> arraylist;
private List<String> mDefaultCheeses;



public TodoRecyclerAdapter(Callback<Result> callback, List<ToDo> results) {
    this.todoResults = results;
    arraylist = new ArrayList<ToDo>();
    arraylist.addAll(todoResults);

}
@Override
public TodoRecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.todo_items, null);
    ViewHolder viewHolder = new ViewHolder(itemLayoutView);
    return viewHolder;
}
@Override
public void onBindViewHolder(final TodoRecyclerAdapter.ViewHolder holder, final int position) {
    holder.todoTitle.setText(todoResults.get(position).getTODO_TITLE().toString());
    String priority = todoResults.get(position).getPriority().toString();
    if (priority.equals("Low")) {
        holder.todoImage.setImageResource(R.drawable.low);
    } else if (priority.equals("Normal")) {
        holder.todoImage.setImageResource(R.drawable.normal);
    } else if (priority.equals("High")) {
        holder.todoImage.setImageResource(R.drawable.high);
    }
}


@Override
public int getItemCount() {
    return  todoResults.size();
}

public static class ViewHolder extends RecyclerView.ViewHolder {
    public TextView todoTitle;
    public ImageView todoImage;
    public ViewHolder(View itemLayoutView) {
        super(itemLayoutView);
        todoTitle = (TextView) itemLayoutView.findViewById(R.id.todo_title);
        todoImage = (ImageView) itemLayoutView.findViewById(R.id.imageView2);
    }}

这是菜单

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.android.nigeriaexams.ui.SettingsFragment">
<item android:id="@+id/action_search"
    android:title="Search"
    android:icon="@drawable/ic_search"
    app:showAsAction="collapseActionView|always"
    app:actionViewClass="android.support.v7.widget.SearchView"
    android:layout_width="wrap_content" />
