span

基于 buildSpannedString 扩展的 DSL，可方便的构建 Spanned，扩展支持了块级样式，文字描边，文字3D风格，标签风格...

• 添加行内内容
  • 换行 br()
  • 图片 image(drawable，width, height, align)
  • 图片 image(context, resourceId，width, height, align)
  • 文本 text(text, spans)
  • 文本 text(text, scale, color，size, typeface, style, bgColor)
• 添加块级内容
  • 块 block(spans) { ... }
  • 段落 paragraph(align, lineHeight, intentFirst, intentRest) { ... }
  • 引述 quote(color) { ... }
  • 列表项 bullet(color) { ... }
• 提供多种兼容性样式，抹平版本差异
  • BulletCompatSpan， API 28 开始 BulletSpan 才支持设置圆点尺寸
  • QuoteCompatSpan， API 29 开始 QuoteSpan 才支持设置指示条宽度和间隔
  • TypefaceCompatSpan， API 28 开始 TypefaceSpan 才支持传入 Typeface
  • LineHeightCompatSpan， API 29 开始才支持 LineHeightSpan.Standard
  • ImageCompatSpan， API 29 开始才支持 ImageSpan.ALIGN_CENTER，且图片高度 > 文本高度时，图片居中失效
• 提供多种自定义样式
  • LabelSpan，标签样式的文本
  • Text3dSpan，3D风格的文本
  • TextStrokeSpan，带描边的文本
  • TextColorSpan，解决 ForegroundColorSpan 与其它有些样式共用时会失效的问题
• 提供多种为文本快捷设置样式的方法
  • 为文本设置样式
    CharSequence.setTextStyle(spans)
  • 为文本中匹配正则表达式(regex)的部分设置样式
    CharSequence.setTextStyle(regex) { arrayOf(spans) }
  • 为文本中匹配正则表达式(regex)的部分设置样式
    CharSequence.setTextStyle(regex, scale, color，size, typeface, style, bgColor)
  • 为文本中的数字设置样式
    CharSequence.setNumberStyle(scale, color，size, typeface, style, bgColor)
  • 为文本设置描边
    CharSequence.setStrokeStyle(strokeColor, strokeWidth, letterSpacing)
  • 为文本列表设置标签样式
    List<String>.setLabelStyle(colors, height，corner, padding, spacing, stroke)
