android：使用Custom AdaptEr

Question

我有一个自定义arraylist的活动，可以容纳5600个项目。 arraylist引用输入的.csv文件，并链接到列表视图以供显示。我遇到的问题是为该列表视图添加搜索功能，以便用户可以在需要更具体的内容时缩小搜索范围。我已经尝试了很多其他教程，但似乎没有任何东西适合我的确切场景。我很感激帮助，希望我能正确地发布这个问题。

这是listview的java类

package com.example.android.practiceapp;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ListView;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class games extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_games);
        InputStream inputStream = getResources().openRawResource(R.raw.slots);
        CSVFile csvFile = new CSVFile(inputStream);
        List<String[]> slots = csvFile.read();
        MyListAdapter adapter=new MyListAdapter(this, R.layout.list_item,R.id.game_title, slots);
        ListView listView=(ListView)findViewById(R.id.list);
        listView.setAdapter(adapter);
    }

    private class CSVFile {
        InputStream inputStream;

        public CSVFile(InputStream inputStream){
            this.inputStream = inputStream;
        }

        public List<String[]> read(){
            //
            List<String[]> resultList = new ArrayList<String[]>();
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
            try {
                String line;
                while ((line = reader.readLine()) != null) {
                    String[] row = line.split(",");
                    resultList.add(row);
                }
            }
            catch (IOException e) {
                Log.e("Main",e.getMessage());
            }
            finally {
                try {
                    inputStream.close();
                }
                catch (IOException e) {
                    Log.e("Main",e.getMessage());
                }
            }
            return resultList;
        }
    }

}

如果需要，ListViewAapter

package com.example.android.practiceapp;

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

import java.util.List;

/**

public class MyListAdapter extends ArrayAdapter<String[]>{
    int groupid;
    List<String[]> items;
    Context context;
    String path;

    public MyListAdapter(Context context, int vg, int id, List<String[]> items){
        super(context,vg, id, items);
        this.context=context;
        groupid=vg;
        this.items=items;

    }
    static class ViewHolder {
        public TextView textid;
        public TextView textname;
        public TextView denom;
        public TextView tech;

    }

    public View getView(int position, View convertView, ViewGroup parent) {

        View rowView = convertView;
        if(rowView==null){
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            rowView= inflater.inflate(groupid, parent, false);
            ViewHolder viewHolder = new ViewHolder();
            viewHolder.textid = (TextView) rowView.findViewById(R.id.game_title);
            viewHolder.textname = (TextView) rowView.findViewById(R.id.location);
            viewHolder.denom = (TextView) rowView.findViewById(R.id.denomination);
            viewHolder.tech = (TextView) rowView.findViewById(R.id.manufacterer);
            rowView.setTag(viewHolder);
        }
        // Fill data
        ViewHolder holder = (ViewHolder) rowView.getTag();
        String[] row=items.get(position);
        holder.textid.setText(row[0]);
        holder.textname.setText(row[1]);
        holder.denom.setText(row[2]);
        holder.tech.setText(row[3]);

        return rowView;
    }

}

这是XML

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/list"
    android:background="@drawable/background"
    android:orientation="vertical"
    android:padding="16dp"
    tools:context="com.example.android.practiceapp.games">
</ListView>
