AndroidでNavigation BarとStatus Barの色を変える

systemUiVisibilityがdeprecatedになったので、コードを見直した
少しはまったので、残しておく

MainActivity.kt

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        setStatusBarColor(android.R.color.black)
        setNavigationBarColor(android.R.color.black)
        window.setLightBackgroundSystemBar()
    }

    private fun AppCompatActivity.setStatusBarColor(colorRes: Int) {
        var colorResTemp = colorRes
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
            colorResTemp = android.R.color.black
        }
        window.statusBarColor = ContextCompat.getColor(this, colorResTemp)
    }

    private fun AppCompatActivity.setNavigationBarColor(colorRes: Int) {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
            return
        }
        window.navigationBarColor = ContextCompat.getColor(this, colorRes)
    }
