Sorry for bothering so much... I'm inspired today 😅

I'm trying to use accompanist system ui controller lib, following this:

https://google.github.io/accompanist/systemuicontroller/

But i found that on light theme icons are not show :S

[Albert Chang]

If you set status bar color to transparent, you have to set WindowCompat.setDecorFitsSystemWindows(window, false) to extend your UI and show something behind the status bar yourself, otherwise since the bar is transparent the default surface color is displayed and dark icons won't be recognizable.

[alorma]

even not setting transparent color it not shows

[alorma]

val systemUiController = rememberSystemUiController()
            val useDarkIcons = MaterialTheme.colors.isLight
            val colorPrimary = MaterialTheme.colors.primaryVariant
            SideEffect {
                systemUiController.setStatusBarColor(
                    color = colorPrimary,
                    darkIcons = useDarkIcons,
                )
            }

[alorma]

still shows the status bar black

[alorma]

because using

android:theme="@android:style/Theme.NoTitleBar"

If I use a material theme, it shows correct

[Albert Chang]

Then just use a material theme.

[Albert Chang]

There is @android:style/Theme.Material.NoActionBar and @android:style/Theme.Material.Light.NoActionBar.

[alorma]

mmmmm

[alorma]

but since which API is available? 21?

[Albert Chang]

Of course. Same as Compose UI.

[alorma]

awesome

[alorma]

thanks, never knew about @android version of material themes

[alorma]

building a project without AppCompat and Material libraries looks so... scary it has been so many years using them

[Colton Idle]

I'm going to hit this problem soon. Thanks @alorma Do you happen to know if theres an Android material daynight theme without having to pull in the entire Material lib?

[Albert Chang]

You can easily create your own.
values/themes.xml:

<style name="Theme.MyApp" parent="android:Theme.Material.Light.NoActionBar" />

values-night/themes.xml:

<style name="Theme.MyApp" parent="android:Theme.Material.NoActionBar" />

[alorma]

anyway, is it needed if you use a pure compose app?

[Colton Idle]

I figured you need DayNight theme in a pure compose app so your splash screen uses the right colors.

[Albert Chang]

Yes, background color, status bar color, navigation bar color, etc from your xml theme will be used when your app is starting.
