重要脚本：UIPanel，UIScrollView，UIDragScrollView，UIWrapContent

记得item挂UIDragScrollView和BoxCollider哦

如下图，先把物体和脚本弄好

ReuseScroll就是自己写的复用脚本了

代码如下：

using UnityEngine;using System.Collections;using System.Collections.Generic;public class ReuseScroll : MonoBehaviour{    /// 
    /// 数据类    /// 
    public class MyData    {        public MyData(string name)        {            this.name = "name_" + name;        }        public string name;    }    public UIWrapContent wrapContent;    private Dictionary
   
     m_index2Item = new Dictionary
    
     ();    /// 
     
    /// 数据列表    /// 
    private List
     
       m_data = new List
      
       ();    protected void Start()    {        InitData();        //启动wrapContent//        wrapContent.enabled = true;        //实现复用的托管方法//        wrapContent.onInitializeItem = (go, wrapIndex, realIndex) =>        {            realIndex = -realIndex;            if (!m_index2Item.ContainsKey(realIndex))            {                m_index2Item.Add(realIndex, go);            }            var actv = realIndex >= 0 && m_data.Count > realIndex;            go.SetActive(actv);            if (actv)                go.GetComponentInChildren
       
        ().text = m_data[realIndex].name;        };    }    protected void Update()    {        //按A键添加数据并更新列表//        if (Input.GetKeyDown(KeyCode.A))        {            var index = m_data.Count;            AddData(new MyData(index.ToString()));            if (m_index2Item.ContainsKey(index))            {                var go = m_index2Item[index];                if (go.transform.localPosition.y <= 0)                {                    go.SetActive(true);                    go.GetComponentInChildren
        
         ().text = m_data[index].name; } } } } /// 
         
 /// 初始化数据 /// 
 private void InitData() { for (int i = 0; i < 4; ++i) { m_data.Add(new MyData(i.ToString())); } } /// 
         
 /// 添加数据 /// 
 private void AddData(MyData data) { m_data.Add(data); }}
        
       
      
     
    
   

希望大家有更好的办法的话，可以分享交流
