Unity实现搜索功能

1、效果展示

2、搭建场景

3、代码

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class xy_try02 : MonoBehaviour
{
    
    
    public InputField m_input;//输入框
    public InputField m_search;//搜索框
    public GameObject m_textPrefab;//Text预制体
    public Transform parent;//Scroll View下的content
    private List<GameObject> m_chattingRecords;//存储聊天记录
    private List<GameObject> m_screeningRecords;//存储筛选后的聊天记录

    // Start is called before the first frame update
    void Start()
    {
    
    
        m_chattingRecords = new List<GameObject>();
        m_input.onEndEdit.AddListener(AddRecord);//输入完毕
        m_search.onValueChanged.AddListener(SearchRecords);//值改变
    }

    private void AddRecord(string content)
    {
    
    
        if (content == "")//输入内容不能为空
            return;
        GameObject t = Instantiate(m_textPrefab);//实例化
        t.transform.SetParent(parent);//设置父物体
        t.GetComponent<Text>().text = DateTime.Now.ToString() + "：" + content;
        m_chattingRecords.Add(t);
        m_input.text = null;
    }

    private void SearchRecords(string connect)
    {
    
    
        m_screeningRecords = new List<GameObject>();
        foreach (var m_chattingRecord in m_chattingRecords)
        {
    
    
            m_chattingRecord.SetActive(false);//隐藏所有物体
            if (m_chattingRecord.GetComponent<Text>().text.Split('：')[1].IndexOf(connect) >= 0)
            {
    
    
                m_screeningRecords.Add(m_chattingRecord);
            }
        }
        foreach (var m_screeningRecord in m_screeningRecords)
        {
    
    
            m_screeningRecord.SetActive(true);
        }
    }
}
