Question

In the new AppCompat library, we can tint the button this way:

Answer 1

If you are using Kotlin and Material Design, you can change color of your MaterialButton like this:

myButton.background.setTintList(ContextCompat.getColorStateList(context, R.color.myColor))

You can improve it even better by creating an extension function for your MaterialButton in order to make you code more readable and your coding little more convenient:

fun MaterialButton.changeColor(color: Int) {
    this.background.setTintList(ContextCompat.getColorStateList(context, color))
}

Then, you can use your function everywhere like this:

myButton.changeColor(R.color.myColor)
