You can override onTouchEvent and create a listener like this :

class MyButton @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = R.attr.materialButtonStyle) : MaterialButton(context, attrs, defStyleAttr) {

    private var onDisableClickListener: OnClickListener? = null

    override fun onTouchEvent(event: MotionEvent?): Boolean {
        if (event?.action == MotionEvent.ACTION_DOWN && !isEnabled) {
            onDisableOnClickListener?.onClick(this)
        }
        return super.onTouchEvent(event)
    }

    fun setOnDisableClickListener(l: OnClickListener?) {
        onDisableClickListener = l
    }
}

In your activity :

button.setOnDisableClickListener {
            Toast.makeText(this), "The button is disabled", Toast.LENGTH_SHORT).show()
}
button.setOnClickListener {
            Toast.makeText(this), "The button is enabled", Toast.LENGTH_SHORT).show()
}
