适配器列表查看过滤器Android

Question

嗨，大家好，请任何人都可以帮助我。我不知道为什么，我不能在我的列表视图适配器中实现过滤器，错误是方法getfilter（）中的“不兼容类型”String“dataNames = mStringFilterList.get（i）;” 这里我的适配器代码：

package com.ekoacak.belajartabhost; 

import android.content.Context; 
import android.util.Log; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.Filter; 
import android.widget.Filterable; 
import android.widget.TextView; 

import java.util.ArrayList; 
import java.util.List;

public class ActorAdapter extends BaseAdapter implements Filterable { 
    Context mContext; 
    LayoutInflater layoutInflater; 
    public ArrayList<Actors> arrayList; 
    public List<Actors> actorsList = null; 
    List<Actors> mStringFilterList; 


    public ActorAdapter(Context context, List<Actors> actorsList) { 
     mContext = context; 
     this.actorsList = actorsList; 
     mStringFilterList = actorsList; 
     layoutInflater = LayoutInflater.from(mContext); 
     this.arrayList = new ArrayList<Actors>(); 
     this.arrayList.addAll(actorsList); 
    } 

    public class ViewHolder{ 
     TextView tvId,tvJudul,tvJenis,tvProvinsi,tvKota,tvdeskrip; 
    } 

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

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

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

    @Override 
    public View getView(int position, View v, ViewGroup parent) { 
     final ViewHolder holder; 
     if (v == null){ 
      holder = new ViewHolder(); 
      v = layoutInflater.inflate(R.layout.data_item, null); 
      holder.tvId = (TextView) v.findViewById(R.id.txtIDwisata); 
      holder.tvJudul = (TextView) v.findViewById(R.id.txtjudulwisata); 
      holder.tvJenis = (TextView) v.findViewById(R.id.txtjeniswisata); 
      holder.tvProvinsi = (TextView) v.findViewById(R.id.txtprovwisata); 
      holder.tvKota = (TextView) v.findViewById(R.id.txtkotawisata); 
      holder.tvdeskrip = (TextView) v.findViewById(R.id.txtdeskripwisata); 
      v.setTag(holder); 
     }else{ 
      holder = (ViewHolder) v.getTag(); 
     } 

     holder.tvId.setText(actorsList.get(position).getId()); 
     holder.tvJudul.setText(actorsList.get(position).getJudul()); 
     holder.tvJenis.setText(actorsList.get(position).getJenis()); 
     holder.tvProvinsi.setText(actorsList.get(position).getProvinsi()); 
     holder.tvKota.setText(actorsList.get(position).getKota()); 
     holder.tvdeskrip.setText(actorsList.get(position).getDeskrip()); 


     return v; 
    } 

    //Filter 
    @Override 
    public Filter getFilter() { 
     Filter filter = new Filter() { 
      @SuppressWarnings("unchecked") 
      @Override 
      protected void publishResults(CharSequence constraint, FilterResults results) { 
       List<String> arrayListNames = (List<String>) results.values; 
       notifyDataSetChanged(); 
      } 

      @Override 
      protected FilterResults performFiltering(CharSequence constraint) { 
       FilterResults results = new FilterResults(); 
       ArrayList<String> FilteredArrayNames = new ArrayList<String>(); 

       // perform your search here using the searchConstraint String. 

       constraint = constraint.toString().toLowerCase(); 
       for (int i = 0; i < mStringFilterList.size(); i++) { 
        String dataNames = mStringFilterList.get(i); 
        if (dataNames.toLowerCase().startsWith(constraint.toString())) { 
         FilteredArrayNames.add(dataNames); 
        } 
       } 
       results.count = FilteredArrayNames.size(); 
       results.values = FilteredArrayNames; 
       Log.e("VALUES", results.values.toString()); 

       return results; 
      } 
     }; 
     return filter; 
    } 

}

改变这一行

String dataNames = mStringFilterList.get(i);

与

Actors dataNames = mStringFilterList.get(i);
