public sealed class StyleConstants extends Object permits StyleConstants.CharacterConstants, StyleConstants.ColorConstants, StyleConstants.FontConstants, StyleConstants.ParagraphConstants

一组众所周知或常见的属性键和方法，用于以类型安全的方式应用于AttributeSet或MutableAttributeSet以获取/设置属性。

段落属性形成要呈现的段落的定义。所有大小都以点（如在后置脚本中找到的）指定，这是一种设备无关的度量。

图表显示段落上方、首行缩进、左缩进、右缩进和段落下方的空间。
