形变
在共享元素的前后布局之间建立连续形变。
实时预览
一个形状平滑地变成另一个形状,例如灵动岛。
术语定义与近义词辨析
英文定义逐字保留自 Animation Vocabulary;中文翻译和辨析帮助你选对术语。
morph形变
MorphOne shape smoothly turns into another shape, e.g. Dynamic Island.
一个形状平滑地变成另一个形状,例如灵动岛。
continuity-transition连续性过渡
Continuity transitionA change that keeps the user oriented by visually connecting before and after. For example, making the same rectangle bigger and smaller.
通过视觉连接变化前后的状态来帮助用户保持方位感,例如让同一个矩形放大或缩小。
连续性过渡是一条保持前后关联的设计原则;形变是实现连续性的具体方式之一。
shared-element-transition共享元素过渡
Shared element transitionAn element travels and transforms from one position into another, like a thumbnail expanding into a card.
同一个元素从一个位置移动并变换到另一个位置,例如缩略图展开成卡片。
共享元素过渡让同一元素跨布局移动并变换;形变强调一个形状变成另一个形状。
layout-animation布局动画
Layout animationWhen an element's size or position changes, it animates to the new spot instead of snapping.
元素尺寸或位置变化时,以动画移动到新状态,而非瞬间跳变。
布局动画把尺寸或位置变化平滑化;形变改变元素的形状。
使用这段动效前的判断
目的、频率、触发、时序、可打断性和手势规则共同决定实现。
让一个形状平滑变为另一个形状,并保持对象身份连续。
适合低频品牌符号、图标和高价值状态变化;常用控件保持更克制。
由对象状态真正改变时触发,前后形状应具有可理解的对应关系。
进入与离开共享同一几何对象和插值路径;复杂路径先统一节点数量。
中断时从当前插值形状转向新目标,避免回到任一端点。
手势驱动形变要把进度连续映射到输入;离散控件提供键盘切换。
使用静态状态替换或短交叉淡化,同时保持对象位置与尺寸连续。

}交付前检查
- 明确区分形变、共享元素过渡和布局动画。
- 检查中间形状不会产生自相交或闪烁。
