Unity搜索组件工具

1.核心搭建就是一个InputField 一个Scroll view 

代码如下:

using System;
using System.Collections.Generic;

using UnityEngine;
using UnityEngine.UI;

/// <summary>
/// Unity 搜索组件：输入框模糊搜索字典Key，Scroll View展示结果，点击结果触发回调
/// </summary>
public class SearchScrollView : MonoBehaviour

    [SerializeField] private RectTransform contentRoot;
    [SerializeField] private GameObject resultItemPrefab;

    [Header("Settings")]
    public static bool isbool = false;
    /// <summary> 数据源：Key=显示文本，Value=关联数据 </summary>
    private Dictionary<string, string> dataSource = new Dictionary<string, string>();

    /// <summary> 点击结果项的回调，参数为 key 和对应的 value </summary>
    public event Action<string, string> OnResultClicked;

    /// <summary> 对象池：缓存已创建的 Item，避免频繁 Instantiate/Destroy </summary>
    private List<GameObject> pool = new List<GameObject>();
    private int poolIndex = 0;

    private void Awake()
    {
        if (searchInput != null)
            searchInput.onValueChanged.AddListener(OnSearchTextChanged);
       
    }

    private void OnDestroy()
    {
        if (searchInput != null)
            searchInput.onValueChanged.RemoveListener(OnSearchTextChanged);
        // 清理对象池
        foreach (var obj in pool)
        {
            if (obj != null) Destroy(obj);
        }
        pool.Clear();
    }

    /// <summary> 设置数据源并刷新展示 </summary>
    public void SetDataSource(Dictionary<string, string> data)
    {
        dataSource = data ?? new Dictionary<string, string>();
        RefreshResults(searchInput != null ? searchInput.text : "");
    }

    /// <summary> 模糊匹配：keyword 包含在 key 中即匹配（忽略大小写） </summary>
    private bool FuzzyMatch(string key, string keyword)
    {
        if (string.IsNullOrEmpty(keyword)) return true;
        return key.IndexOf(keyword, StringComparison.OrdinalIgnoreCase) >= 0;
