background color on Button in Jetpack Compose

问题

Button(backgroundColor = Color.Yellow) {
       Row {
            Image(asset = image)
            Spacer(4.dp)
            Text("Button")
           }
    }

I can not figure out why I can't use background color on Button I followed on Compose Layout codelabs there is a problem in backgroundColor and asset in Image(). Please help me figure out how to use Buton, I'm still new

回答1:

The backgroundColor for Button no longer work in 1.0.0-alpha7

Use the below instead

Button(
   onClick = {},
   colors = ButtonConstants.defaultButtonColors(backgroundColor = Color.Yellow)
) {
   /**/
}

You can use:

val image =  imageResource(R.drawable.xxx)

Button(
        onClick = {  },
        backgroundColor = Color.Yellow) {
    Row {
        Image(asset = image)
        Spacer(Modifier.preferredSize(4.dp))
        Text("Button")
    }
}
