颜色

React Native 中的组件是使用 JavaScript 进行样式化的。颜色属性通常与 Web 上的 CSS 工作方式相匹配。每个平台上关于颜色使用的一般指南如下:

颜色相关的 API

React Native 有几个颜色 API,旨在让您充分利用平台的设计和用户偏好。

  • PlatformColor 允许您引用平台的颜色系统。
  • DynamicColorIOS 是 iOS 特有的,可以让您指定在浅色或深色模式下使用哪些颜色。

颜色的表示形式

红-绿-蓝 (RGB)

React Native 支持 rgb()rgba() 两种十六进制与函数方法

  • '#f0f' (#rgb)
  • '#ff00ff' (#rrggbb)
  • 'rgb(255, 0, 255)'
  • 'rgba(255, 255, 255, 1.0)'

色调-饱和度-亮度 (HSL)

也支持 hsl()hsla() 函数方法:

  • 'hsl(360, 100%, 100%)'
  • 'hsla(360, 100%, 100%, 1.0)'

颜色值

React Native 还支持将颜色表示为int值(以 RGB 颜色模式):

  • 0xff00ff00 (0xrrggbbaa)
注意

这看起来可能与 Android Color 的整数表示类似,但在 Android 上的值是以 SRGB 颜色模式(0xaarrggbb)存储的。

全透明 transparent

全透明颜色值rgba(0,0,0,0) 有个单独的写法,和CSS3一致:

  • 'transparent'

颜色名称

你还可以使用颜色名称来作为颜色值. React Native 遵循CSS3 规范
