Java 无法解析Recyclerview.adapter的适配器类上的getFilter（）方法

我正在使用实现Filterable接口的RecyclerView.Adapter类创建一个

RecylerView

。我已经彻底检查了我的代码，但可以找到错误的原因。当我在SearcView的

setOnQueryTextListener.onQueryTextChange

方法中使用此适配器类时，它显示“无法解析

getFilter（）

方法”

以下是自定义RecyclerView.Adapter类的代码：

public class CUGAdapter extends RecyclerView.Adapter<CUGAdapter.CUGViewHolder> implements Filterable {
private ArrayList<Contact> CUG;
private ArrayList<Contact> filteredCUG;


public class CUGViewHolder extends RecyclerView.ViewHolder{
    public TextView emp_id;
    public TextView emp_name;
    public TextView emp_designation;
    public TextView emp_mobile;
    public View layout;

    public CUGViewHolder(View v) {
        super(v);
        this.layout = v;
        this.emp_id = (TextView) v.findViewById(R.id.txt_empid);
        this.emp_name = (TextView) v.findViewById(R.id.txt_name);
        this.emp_designation = (TextView) v.findViewById(R.id.txt_designation);
        this.emp_mobile = (TextView) v.findViewById(R.id.txt_mobile);

    }
}

public CUGAdapter(ArrayList<Contact> CUG) {
    this.CUG = CUG;
}

@Override
public CUGAdapter.CUGViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View v = inflater.inflate(R.layout.listview_layout, parent, false);
    CUGViewHolder vh = new CUGViewHolder(v);
    return vh;
}

@Override
public void onBindViewHolder(CUGViewHolder holder, int position) {
    Contact c = filteredCUG.get(position);
    holder.emp_mobile.setText(c.mobile);
    holder.emp_designation.setText(c.designation);
    holder.emp_name.setText(c.name);
    holder.emp_id.setText(c.empid);
}

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

@Override
public Filter getFilter() {
    return new Filter() {
        private ArrayList<Contact> filtered = new ArrayList<Contact>();
        @Override
        protected FilterResults performFiltering(CharSequence charSequence) {
            String charString = charSequence.toString().toLowerCase();
            filtered.clear();
            if(charString.isEmpty()){
                filtered = CUG;
                //filteredCUG = CUG;
            }
            else{
                for (Contact cug : CUG){
                    if( cug.name.toLowerCase().contains(charString) || cug.mobile.toLowerCase().contains(charString) || cug.empid.toLowerCase().contains(charString)){
                        filtered.add(cug);
                    }
                 }
                 //filteredCUG = filtered;
            }
            FilterResults filterResults = new FilterResults();

            filterResults.values = filtered;
            return filterResults;
        }

        @Override
        protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
            //filteredCUG.clear();
            filteredCUG = (ArrayList<Contact>) filterResults.values;
            notifyDataSetChanged();
        }
    };
}}

将适配器初始化更改为

 CUGAdapter adapter = new CUGAdapter(this.cuglist);

显示适配器初始化语句..RecyclerView.adapter adapter=new-CUGAdapter（this.cuglist）；谢谢兄弟。。我必须使用CUGAdapter适配器。

 CUGAdapter adapter = new CUGAdapter(this.cuglist);
