        { 
            Debug.Log("slideValue:" + f);
    
        }
    
    }

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using UnityEngine.UI;
    
    public class LearnDropdown : MonoBehaviour
    { 
        public Dropdown dropdown;
        public void Awake()
        { 
            dropdown.onValueChanged.AddListener(this.OnValueChanged);
        }
        public void OnValueChanged(int value) { 
            Debug.Log("DropdownValue:" + value);
        }
    
    }

Scrollbar

using System.Collections;
    using System.Collections.Generic;

    using UnityEngine.UI;
    
    public class LearnScrollBar : MonoBehaviour
    { 
        public Scrollbar scrollbar;
        public void Awake()
        { 
            scrollbar.onValueChanged.AddListener(this.OnValueChanged);
        }
        public void OnValueChanged(float f)
        { 
            Debug.Log("srcollBarValue:" + f);
        }
    
    }

为每个UI分别添加C\#脚本，然后每个ui比如dropdown绑定代码中`public Dropdown dropdown`

然后play  
分别操作相应控件，控制台就会打印出相应信息  
如下
