Jetpack Compose not taking the colorScheme-CodePudding

I have an android app written in Jetpack Compose. I am trying to set Icon colors using the defined colorScheme in my app, but it's not working.

Below is my code.

Color.kt

import androidx.compose.ui.graphics.Color

val green = Color(0xFF61FF67)

Theme.kt

private val MesColorDark = darkColorScheme(
        primary = green,
        secondary = green,
        tertiary = green,
        surface = green
)

private val MesColorLight = lightColorScheme(
        primary = green,
        secondary = green,
        tertiary = green,
        surface = green
)

@Composable
fun MesTheme(
    darkTheme: Boolean = isSystemInDarkTheme(),
    content: @Composable () -> Unit
) {
    val mesColorScheme =
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
            val context = LocalContext.current
            if (darkTheme) dynamicDarkColorScheme(context) else dynamicLightColorScheme(context)
        } else {
            if (darkTheme) MesColorDark else MesColorLight
        }

    MaterialTheme(
        colorScheme = mesColorScheme,
        typography = MesTypography,
        content = content
    )
}

colors.xml

<?xml version="1.0" encoding="utf-8"?>

<resources>
    <!-- Status bar -->
    <color name="black30">#4D000000</color>
</resources>

themes.xml

<resources>

    <style name="Platform.Theme.Mes" parent="android:Theme.Material.Light.NoActionBar">
        <item name="android:statusBarColor">@color/black30</item>
    </style>

    <style name="Theme.Mes" parent="Platform.Theme.Mes" />

</resources>

Then I have an icon defined as such:

Icon(
imageVector = Icons.Outlined.Phone,
contentDescription = "Open navigation drawer",
tint = MaterialTheme.colorScheme.primary
)

This is the output:

As you can see, this color has not been defined in the color scheme. Even if I use surface, background etc... it still doesn't become green

However, if i use this code instead:

Icon(
imageVector = Icons.Outlined.Phone,
contentDescription = "Open navigation drawer",
tint = Colors.Green
)

It changes to this:

Can someone please help on why the colorScheme is not working ?

CodePudding user response：

val mesColorScheme = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
    val context = LocalContext.current
    if (darkTheme) dynamicDarkColorScheme(context) else dynamicLightColorScheme(context)
} else {
    if (darkTheme) DarkColorScheme else LightColorScheme
}

Please check the above code in Theme.kt file. Since you are using Android S or greater, dynamic color will be enabled. Please change that code like below.

val mesColorScheme = if (darkTheme) DarkColorScheme else LightColorScheme

Add onPrimary like this

private val MesColorDark = darkColorScheme(
    primary = green,
    onPrimary = green,
    primaryContainer =green,
    onPrimaryContainer = green
)
