浮动操作按钮 (FAB) 代表应用中的主要操作。默认情况下，它们具有圆形形状。按下时，该按钮可能会打开更多相关操作。
¥Floating Action Buttons (FABs) represent the primary action in an application. By default, they have a circular shape. When pressed, the button may open more related actions.
顾名思义，FAB 通常浮动在内容上的固定位置。这是通过将 fab 按钮封装在 fab 组件中来实现的。如果按钮没有用 fab 封装，它将随内容一起滚动。
¥As the name suggests, FABs generally float over the content in a fixed position. This is achieved by wrapping the fab button in a fab component. If the button is not wrapped with a fab, it will scroll with the content.
