Answer 1

[Kotlin version] I created this extension that also checks if the desired color has enough contrast to hide the System UI, like Battery Status Icon, Clock, etc, so we set the System UI white or black according to this.

fun Activity.coloredStatusBarMode(@ColorInt color: Int = Color.WHITE, lightSystemUI: Boolean? = null) {
    var flags: Int = window.decorView.systemUiVisibility // get current flags
    var systemLightUIFlag = View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
    var setSystemUILight = lightSystemUI

    if (setSystemUILight == null) {
        // Automatically check if the desired status bar is dark or light
        setSystemUILight = ColorUtils.calculateLuminance(color) < 0.5
    }

    flags = if (setSystemUILight) {
        // Set System UI Light (Battery Status Icon, Clock, etc)
        removeFlag(flags, systemLightUIFlag)
    } else {
        // Set System UI Dark (Battery Status Icon, Clock, etc)
        addFlag(flags, systemLightUIFlag)
    }

    window.decorView.systemUiVisibility = flags
    window.statusBarColor = color
}

private fun containsFlag(flags: Int, flagToCheck: Int) = (flags and flagToCheck) != 0

private fun addFlag(flags: Int, flagToAdd: Int): Int {
    return if (!containsFlag(flags, flagToAdd)) {
        flags or flagToAdd
    } else {
        flags
    }
}

private fun removeFlag(flags: Int, flagToRemove: Int): Int {
    return if (containsFlag(flags, flagToRemove)) {
        flags and flagToRemove.inv()
    } else {
        flags
    }
}
