如何使动态生成的按钮在Scrollview中可滚动？

using UnityEngine;
using UnityEngine.UI;

public class ScrollViewButtonGenerator : MonoBehaviour
{
    public GameObject buttonPrefab; // 按钮的预制体
    public int buttonCount; // 按钮的数量
    public float buttonHeight; // 按钮的高度

    private void Start()
    {
        // 获取ScrollView和Content组件
        ScrollView scrollView = GetComponent<ScrollView>();
        RectTransform content = scrollView.content;

        // 设置Content组件的高度
        float contentHeight = buttonCount * buttonHeight;
        content.sizeDelta = new Vector2(content.sizeDelta.x, contentHeight);

        // 动态生成按钮
        for (int i = 0; i < buttonCount; i++)
        {
            // 实例化按钮预制体
            GameObject button = Instantiate(buttonPrefab, content);

            // 设置按钮的位置和大小
            RectTransform buttonRect = button.GetComponent<RectTransform>();
            buttonRect.anchoredPosition = new Vector2(0, -i * buttonHeight);
            buttonRect.sizeDelta = new Vector2(content.sizeDelta.x, buttonHeight);

            // 设置按钮的文本
            Text buttonText = button.GetComponentInChildren<Text>();
            buttonText.text = "Button " + (i + 1);
        }
    }
}
