为了更方便地为UI视图添加动画，将动画的编辑功能封装在了UI View类中，可以通过编辑器快速的为视图编辑动画。动画分为两种类型，一种是Unity中的Animator动画，该类型直接通过一个字符串类型变量记录动画State状态的名称即可，播放时调用Animator类中的Play方法传入该名称。另一种是DoTween动画，支持视图的移动、旋转、缩放、淡入淡出动画的编辑：

首先看一下动画相关的几个类的数据结构：

在UI View类中的相关变量如下：

using System;
using UnityEngine.Events;

    public class ViewVisibilityChangedEvent
