我需要根据一个实现搜索功能EditText，以我的RecyclerView。键入时必须过滤列表。

这是代码：

DisplayAdapter.java，这是适配器

public class DisplayAdapter extends RecyclerView.Adapter<DisplayAdapter.MyViewHolder>{
    private List<DataHolder> displayedList;
    public class MyViewHolder extends RecyclerView.ViewHolder{
        public TextView english_d;
        public MyViewHolder(View view){
              super(view);
              english_d = (TextView) view.findViewById(R.id.engword);
        }
   }
    public DisplayAdapter(List<DataHolder> displayedList){
        this.displayedList = displayedList;
      }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int position)    {
    // create a layout
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);

    return new  MyViewHolder(itemView);
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    DataHolder content = displayedList.get(position);
    holder.english_d.setText(content.getEnglish());
   }
@Override
public int getItemCount() {
    return displayedList.size();
   }
}

DataHolder.java

public class DataHolder {
private String english;


public DataHolder() {
}

public DataHolder(String english, String german) {
    this.english = english;
   
}

public String getEnglish() {
    return english;
}

public void setEnglish(String english) {
    this.english = english;
   }

}

这是我正在使用的片段：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.activity_two_fragment, container, false);

        rv = (RecyclerView) view.findViewById(R.id.list_view_english);
        rv.setHasFixedSize(true);
       
        inputSearch = (EditText) view.findViewById(R.id.inputSearch);
        
        rv.addItemDecoration(new DividerItemDecoration(getActivity(), LinearLayoutManager.VERTICAL));
        final LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
        rv.setLayoutManager(layoutManager);

        
        DisplayContent();
        

        disp_adapter = new DisplayAdapter(displayedList);
        
        rv.setAdapter(disp_adapter);
   return view;
}
