How to change the color of a SwitchCompat

Notice the low constrast in my switch:<

I was having the same problem. Finally solved it programatically with this Kotlin code

fun tintSwitchButton(sw: SwitchCompat, resolvedColor: Int) {
    val states = arrayOf(
            intArrayOf(-android.R.attr.state_pressed),
            intArrayOf(android.R.attr.state_pressed)
    )

    DrawableCompat.setTintList(sw?.trackDrawable, ColorStateList(
            states,
            intArrayOf(resolvedColor, resolvedColor)
    ))

    DrawableCompat.setTintList(sw?.thumbDrawable, ColorStateList(
            states,
            intArrayOf(Color.WHITE, Color.WHITE)
    ))
}

And the function call is

tintSwitchButton(switchCompat, Color.rgb(214, 0, 0))

You can also create an extension function:

fun SwitchCompat.tint(resolvedColor: Int) {
    val states = arrayOf(
        intArrayOf(-android.R.attr.state_pressed),
        intArrayOf(android.R.attr.state_pressed)
    )

    DrawableCompat.setTintList(trackDrawable, ColorStateList(
        states,
        intArrayOf(resolvedColor, resolvedColor)
    ))

    DrawableCompat.setTintList(thumbDrawable, ColorStateList(
        states,
        intArrayOf(Color.WHITE, Color.WHITE)
    ))
}

So the call would be easier

switchCompat.tint(Color.rgb(214,0,0))
