我正在尝试过滤使用此ArrayAdapter填充的ListView:

package me.alxandr.android.mymir.adapters;

import java.util.ArrayList;
import java.util.Collection;
import java.util.Collections;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Set;

import me.alxandr.android.mymir.R;
import me.alxandr.android.mymir.model.Manga;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Filter;
import android.widget.SectionIndexer;
import android.widget.TextView;

public class MangaListAdapter extends ArrayAdapter<Manga> implements SectionIndexer
{
    public ArrayList<Manga> items;
    public ArrayList<Manga> filtered;
    private Context context;
    private HashMap<String, Integer> alphaIndexer;
    private String[] sections = new String[0];
    private Filter filter;
    private boolean enableSections;

    public MangaListAdapter(Context context, int textViewResourceId, ArrayList<Manga> items, boolean enableSections)
    { …

我尝试使用自定义适配器过滤listview.当我开始在edittext上输入时,应该过滤列表视图.下面是适配器的代码.自定义对象具有重写的方法toString,它返回facebook用户的名称.我没有覆盖ArrayAdapter方法getItem,添加或删除.

public class FacebookFriendsAdapter extends ArrayAdapter<FacebookUser> {
    private Activity activity;
    public ImageLoader imageLoader;
    private HashMap<String, Integer> alphaIndexer;
    private String[] sections = new String[0];
    private boolean enableSections;

    public FacebookFriendsAdapter(Context context, int textViewResourceId,ArrayList<FacebookUser> newItems) {
        super(context, textViewResourceId, newItems);
        imageLoader = new ImageLoader(context.getApplicationContext());
    }

    public static class ViewHolder {
        public TextView text;
        public ImageView image;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View rowView = convertView;
        FacebookUser fcbu = getItem(position);

        if (convertView == null) {
            LayoutInflater vi = (LayoutInflater) …

我想实现getFilter()我的功能ListView,但每次我输入的东西EditText我ListView就会消失.

我的SetHelpRows档案:

public class SetHelpRows {
    String name;
    String id;

    public String getName () {
        return name;
    }

    public void setName (String name) {
        this.name = name;
    }

    public String getID () {
        return id;
    }

    public void setID (String id) {
        this.id = id;
    }

    public SetHelpRows(String name, String id) {
        super();
        this.name = name;
        this.id = id;
    }
}
