切片组件不同于列表项，可以定制内容，显示在搜索结果中。

用法

Slices display rich content and actions on components, appearing as part of search results in the Google search app. They can display a variety of content types, such as text, images, and actions.

原则

专注 切片专注于一个任务或一组相关任务，用于突出显示最重要的信息。 Slices focus on one task, or a set of related tasks, and highlight the most important information.

关联 切片仅提供完成任务所需的信息和控件，与用户息息相关。 Slices provide only the information and controls needed to complete a task.

使用时间

设计者需要根据上下文来确定要显示的切片类型。

在搜索结果中，切片类型受切片与搜索结果的相关性影响。

Android’s Presenter determines the appropriate type of slice to display based on context. In search, the type of slice is influenced by how relevant a slice is to the search results.

结构

切片包含标题和一行或多行交互式内容。各种元素组合在一起以创建切片，例如列表，网格或图像。

Slices contain a header and one or more rows of interactive content. Various elements are grouped together to create a slice, such as a list, grid, or images.
