ScrollView 的父子层次如下：

在ScrollView中添加的组件如下

在ViewPort中添加的组件如下：

在Content中添加的组件如下：

在ScrollView 中绑定的脚本如下：

using UnityEngine;using System.Collections;using UnityEngine.UI;using UnityEngine.EventSystems;using System;public class ScrollViewTest : MonoBehaviour,IBeginDragHandler,IEndDragHandler {    private ScrollRect scrollRect;    private float[] rateArr;    //获取Content的RectTransform    private RectTransform contentTransform;    //设置添加的预制体    public RectTransform itemTransform;    // Use this for initialization    void Start () {        //获取自身的ScrollRect组件        scrollRect = GetComponent<ScrollRect>();        contentTransform = transform.Find("ViewPort").Find("Content").GetComponent<RectTransform>();    }    // Update is called once per frame    void Update () {        //按A键添加子物体        if (Input.GetKeyDown(KeyCode.A))        {            Transform temp = Instantiate(itemTransform).transform;            temp.SetParent(contentTransform);            temp.localPosition = Vector3.zero;            temp.localRotation = Quaternion.identity;            temp.localScale = Vector3.one;        }    }}
