【问题描述】：
我的自定义适配器有以下代码：
package com.tag.instagramdemo.example;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import android.support.v7.widget.RecyclerView;
import android.util.Log;
import android.widget.Filter;

import android.widget.ImageView;
import android.widget.TextView;
import com.tag.instagramdemo.R;
import com.tag.instagramdemo.lazyload.ImageLoader;
public class RelationShipAdapter extends BaseAdapter implements Filterable {
private InstagramApp mApp;
private ListView lvRelationShipAllUser;
public ArrayList<HashMap<String, String>> usersInfo;
private ArrayList<HashMap<String, String>> usersInfo1;
private List<String> originalData = null;
private ArrayList<HashMap<String, String>> filteredData= null;
private LayoutInflater mInflater;
private ItemFilter mFilter = new ItemFilter();
private LayoutInflater inflater;
private LayoutInflater inflater1;
//lvRelationShipAllUser = (ListView) findViewById(R.id.lvRelationShip);
private ImageLoader imageLoader;
Context context;
public RelationShipAdapter(Context context,
ArrayList<HashMap<String, String>> usersInfo,ArrayList<HashMap<String, String>> usersInfo1) {
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater1 = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Log.d("OkHttp","debug4");
this.usersInfo = usersInfo;
this.usersInfo1 = usersInfo1;
//getFilter();
this.imageLoader = new ImageLoader(context);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = inflater.inflate(R.layout.relationship_inflater, null);
View view1 = inflater1.inflate(R.layout.relationship_inflater_nothing, null);
Log.d("usersInfonlist", "ImHere");
Holder holder = new Holder();
//holder.tvFullName1 = (TextView) view1.findViewById(R.id.tvFullName);
//connectOrDisconnectUser();
holder.ivPhoto = (ImageView) view.findViewById(R.id.ivImage);
holder.tvFullName = (TextView) view.findViewById(R.id.tvFullName);
holder.tvFullName.setText(usersInfo.get(position).get(
Relationship.TAG_USERNAME));
Log.d("tvFullNameTestIng",usersInfo.get(position).get(
Relationship.TAG_USERNAME));
imageLoader.DisplayImage(
usersInfo.get(position).get(Relationship.TAG_PROFILE_PICTURE),
holder.ivPhoto);
return view;
}
@Override
public Filter getFilter() {
Log.d("OkHttpNList1", String.valueOf(mFilter));
return mFilter;
}
private class Holder {
private ImageView ivPhoto;
private TextView tvFullName;
private TextView tvFullName1;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return usersInfo.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
private class ItemFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
Log.d("OkHttpNList", "here1");
//MAKE AT THE BEGINING
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
ArrayList<HashMap<String, String>> list = usersInfo;
int count = list.size();
ArrayList<HashMap<String, String>> nlist = new ArrayList(count);
String filterableString;
Log.d("OkHttpNList", String.valueOf(list));
for (int i = 0; i < count; i++) {
filterableString = list.get(i).get("username");
Log.d("OkHttpNList", String.valueOf(filterableString));
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(list.get(i));
}
}
Log.d("OkHttpNList", String.valueOf(nlist));
results.values = nlist;
return results;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
usersInfo = (ArrayList<HashMap<String, String>>) results.values;
Log.d("OkHttpNList", String.valueOf(usersInfo));
notifyDataSetChanged();
}
}
}
当我在搜索视图中输入一些文本以更改我的列表视图时，我的代码现在出现问题，一切正常，但是当我更改文本时，列表视图将使用之前更改的列表进行编辑，而不是原来的那个。
例如，如果我的列表是：a,b,c
然后我输入'a'，'a'就会出现。但是当我删除'a'时，它不会像我想要的那样回到a，b，c。请帮忙：
编辑：如果您需要更多代码，请告诉我。
