How to Convert androidx.compose.ui.graphics.Color to android.graphics.Color (int)

How to convert from Compose Color to Android Color Int?

I am using this code for the moment and it seems to be working, I can't seem to find a function to get the Int value of the color

Color.rgb(color.red.toInt(), color.green.toInt(), color.blue.toInt())

where Color.rgb is a function android.graphics.Color that returns an Integer color and color variable is just a Compose Color !

Since the float one requires higher API

You can use the toArgb() method

Converts this color to an ARGB color int. A color int is always in the sRGB color space

Something like:

//Compose Color androidx.compose.ui.graphics
val Teal200 = Color(0xFFBB86FC)

//android.graphics.Color
val color = Teal200.toArgb()

You can also use something like:

//android.graphics.Color
val color = android.graphics.Color.argb(
      Teal200.toArgb().alpha,
      Teal200.toArgb().red,
      Teal200.toArgb().green,
      Teal200.toArgb().blue
    )

Worked for me convert to Argb, then convert to string:

fun Int.hexToString() = String.format("#%06X", 0xFFFFFF and this)

fun getStringColor(color: Color): String {
  return color.toArgb().hexToString()
}   

fun someOperation() {
  val color = Color.White //compose color
  val colorAsString = getStringColor(color)
  print(colorAsString)
}


// Result will be: "#FFFFFF"

The Android Compose Color class now has function toArgb(), which converts to Color Int.

The function documentation says:

Converts this color to an ARGB color int. A color int is always in the sRGB color space. This implies a color space conversion is applied if needed.

-> No need for a custom conversion function anymore.

Here's a spin on the answer from @gabriele with some Kotlin sugar:

//Compose Color androidx.compose.ui.graphics
val Teal200 = Color(0xFFBB86FC)

fun Color.toAGColor() = toArgb().run { android.graphics.Color.argb(alpha, red, green, blue) }

//android.graphics.Color
val color = Teal200.toAGColor()

What worked for me is:

color.hashCode()
