如何使用红、绿、蓝值创建颜色？- Jetpack 组合

Question

我正在尝试使用RGB值创建颜色，但出现以下错误。我无法找到解决方案。

Color(148f, 148f, 148f, 1f)

以下是我收到的错误：

java.lang.IllegalArgumentException: red = 148.0, green = 148.0, blue = 148.0, alpha = 1.0 outside the range for sRGB IEC61966-2.1 (id=0, model=Rgb)

我检查了 Color 类的代码，发现我需要指定ColorSpace，但我无法找到适合ColorSpace我的要求的。

Answer 1

您使用的构造函数期望在 range 中浮动0..1。

使用Int值代替：

Color(148, 148, 148, 255)
