在子级有ScrollRect组件的对象添加以下脚本:

using UnityEngine;using System.Collections;using UnityEngine.UI;using UnityEngine.EventSystems;public class DragEventSyn : MonoBehaviour, IEndDragHandler, IBeginDragHandler, IDragHandler{    public ScrollRect parentScrollRect;    void Start(){        if(parentScrollRect==null){            GameObject parentScrollRectObj=GameObject.Find("Canvas-category/Scroll View-content");            Debug.Log(parentScrollRectObj);            parentScrollRect=parentScrollRectObj.GetComponent
     
      ();        }    }    public void OnEndDrag(PointerEventData eventData){        if (parentScrollRect){            parentScrollRect.OnEndDrag(eventData);        }    }    public void OnBeginDrag(PointerEventData eventData){        if (parentScrollRect){            parentScrollRect.OnBeginDrag(eventData);        }    }    public void OnDrag(PointerEventData eventData){        if (parentScrollRect){            parentScrollRect.OnDrag(eventData);        }    }}
