    将脚本挂载在ScrollView结构下需要响应时间的对象上

    [csharp] view plain copy

    using UnityEngine.UI;

    using UnityEngine.EventSystems;

    using UnityEngine;

    public class GDragEventDispatcher : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler

    { 

    ScrollRect anotherScrollRect;  

private Image thisRaycast;  

void Awake()  
{  
    //FindScrollRect(gameObject);  
    //if (anotherScrollRect)  
    //{  
    //    thisRaycast = gameObject.GetComponent<Image>();  
    //}  
}  
void Start()  
{  
    FindScrollRect(gameObject);  
    if (anotherScrollRect)  
    {  
        thisRaycast = gameObject.GetComponent<Image>();  
    }  
}  

private void FindScrollRect(GameObject obj)  
{  
    GameObject tempObj = obj.transform.parent.gameObject;  
    //Debug.Log("测试"+tempObj.gameObject.name);  
    anotherScrollRect = tempObj.GetComponent<ScrollRect>();  
    if (anotherScrollRect)  
    {  
        //Debug.Log(anotherScrollRect.gameObject.name);  
        return;  
    }  
    else  
    {  
        FindScrollRect(tempObj);  
    }  
}  

public void OnBeginDrag(PointerEventData eventData)  
{  
    if (anotherScrollRect)  
    {  
        anotherScrollRect.OnBeginDrag(eventData);  
    }  
    if (thisRaycast)  
    {  
        thisRaycast.raycastTarget = false;  
    }  
}  

public void OnDrag(PointerEventData eventData)  
{  
    if (anotherScrollRect)  
    {  
        anotherScrollRect.OnDrag(eventData);  
    }  
}  

public void OnEndDrag(PointerEventData eventData)  
{  
    if (anotherScrollRect)  
    {  
        anotherScrollRect.OnEndDrag(eventData);  
    }  
    if (thisRaycast)  
    {  
        thisRaycast.raycastTarget = true;  
    }  
}

    }
