リストビューでアイテムとサブアイテムを使用して、リストビューでAndroidアプリを作成しようとしています。テキストのフィルタリングを除いて、すべてが機能します。私はいつも使ってきました

list.setTextFilterEnabled(true);

しかし、何かを入力すると、リスト内のすべてが消えます。これが私のMainActivityです：

package com.macura.chatdictionary;

import java.util.ArrayList;
import android.os.Bundle;
import android.app.Activity;
import android.app.SearchManager;
import android.content.Context;
import android.text.TextUtils;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.inputmethod.InputMethodManager;
import android.widget.ListView;
import android.widget.SearchView;

public class MainActivity extends Activity {

    public ListView lv;
    private CustomAdapter adapter;
    private ArrayList<Custom> fetch = new ArrayList<Custom>();



String[] from = new String[] { "title", "description" };
int[] to = new int[] { R.id.title, R.id.description };



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Custom one = new Custom("Big1","Small1");
    Custom two = new Custom("Big2","Small2");
    Custom three = new Custom("Big3","Small3");
    fetch.add(one);
    fetch.add(two);
    fetch.add(three);

    lv = (ListView) findViewById(R.id.listView1);
    adapter = new CustomAdapter(MainActivity.this,
            R.id.listView1,
            fetch);
    lv.setAdapter(adapter);
    lv.setTextFilterEnabled(true);


    }

public void filterItems(String newItem){

}    

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main_actionbar, menu);
    getMenuInflater().inflate(R.menu.main, menu);

    // Associate searchable configuration with the SearchView
    SearchManager searchManager =
           (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    final SearchView searchView =
            (SearchView) menu.findItem(R.id.search).getActionView();
    searchView.setSearchableInfo(
            searchManager.getSearchableInfo(getComponentName()));

    final SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() { 
        @Override 
        public boolean onQueryTextChange(String newText) {

            if (TextUtils.isEmpty(newText)) {
                lv.clearTextFilter();
            } else {
                lv.setFilterText(newText);
            }
            return true;
        } 

        @Override 
        public boolean onQueryTextSubmit(String query) { 

            InputMethodManager imm = (InputMethodManager)getSystemService(
                      Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(searchView.getWindowToken(), 0);
            return true; 
        } 
    }; 

    searchView.setOnQueryTextListener(queryTextListener); 

    return true;
    }



}

これは私の CustomAdapter.java です:

package com.macura.chatdictionary;

import java.util.ArrayList;

import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class CustomAdapter extends ArrayAdapter<Custom>{
private ArrayList<Custom> entries;
private Activity activity;

public CustomAdapter(Activity a, int textViewResourceId, ArrayList<Custom> entries) {
    super(a, textViewResourceId, entries);
    this.entries = entries;
    this.activity = a;
}

public static class ViewHolder{
    public TextView item1;
    public TextView item2;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;
    ViewHolder holder;
    if (v == null) {
        LayoutInflater vi =
            (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(R.layout.listview_layout, null);
        holder = new ViewHolder();
        holder.item1 = (TextView) v.findViewById(R.id.title);
        holder.item2 = (TextView) v.findViewById(R.id.description);
        v.setTag(holder);
    }
    else
        holder=(ViewHolder)v.getTag();

    final Custom custom = entries.get(position);
    if (custom != null) {
        holder.item1.setText(custom.getcustomBig());
        holder.item2.setText(custom.getcustomSmall());
    }
    return v;
}

}

これは私の Custom.java です:

package com.macura.chatdictionary;

public class Custom {
private String customBig;
private String customSmall;

public Custom(String string, String string2) {
this.customBig = string;
this.customSmall = string2;
}
public String getcustomBig() { return customBig; }
public void setcustomBig(String customBig) { this.customBig = customBig; }

public String getcustomSmall() { return customSmall; }
public void setcustomSmall(String customSmall) { this.customSmall = customSmall; }
}

そして、これは私の listview_layout.xml です:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
    android:id="@+id/title"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:textColor="#000000"
    android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
    android:id="@+id/description"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textSize="15sp"
    android:textColor="#000000"
    android:textAppearance="?android:attr/textAppearanceSmall" />

</LinearLayout>

テキストのフィルタリングを機能させるにはどうすればよいですか?

アダプターのフィルター

            adapter.getFilter().filter("filter text", new FilterListener()
            {
                @Override
                public void onFilterComplete(int count)
                {
                   // do some thing when filter complete
                }
            });
