此解决方案仅适用于API >= 23。 在API级别30中，setSystemUiVisibility()已弃用。因此你应该像下面这样使用WindowInsetsControllerCompat

fun changeColorStatusBar(color: Int = R.color.white) {
        val window: Window = window
        val decorView = window.decorView
        val wic = WindowInsetsControllerCompat(window, decorView)
        wic.isAppearanceLightStatusBars = true
        // And then you can set any background color to the status bar.
        window.statusBarColor = ContextCompat.getColor(this, color)
    }

Java开发人员:

正如@Niels所说，你必须在values-v21/styles.xml中放置:

<item name="android:statusBarColor">@color/black</item>

但是如果你想要单个样式。xml，需要添加工具:targetApi="lollipop"，比如:

<item name="android:statusBarColor" tools:targetApi="lollipop">@color/black</item>

对于Kotlin开发者:

window.statusBarColor = ContextCompat.getColor(this, R.color.color_name)

只需在styles.xml文件中添加这些行

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- This is used for statusbar color. -->
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <!-- This is used for statusbar content color. If statusbarColor is light, use "true" otherwise use "false"-->
    <item name="android:windowLightStatusBar">false</item>
</style>

        val window: Window = window

    }

将colorPrimaryDark更改为您想要的颜色到res/values/styles.xml文件中

    <resources>
        <color name="colorPrimary">#800000</color>
        <color name="colorPrimaryDark">#303F9F</color> //This Line
        <color name="colorAccent">#FF4081</color>
        <color name="red">#FF0000</color>
        <color name="white">#FFFFFF</color>
       <color name="cream">#fffdd0</color>
       <color name="burgundy">#800000</color>
    </resources>

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
    <!-- Primary brand color. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorPrimaryVariant">@color/colorPrimaryDark</item>
    <item name="colorOnPrimary">@color/white</item>
    <!-- Secondary brand color. -->
    <item name="colorOnSecondary">@color/black</item>
    <!-- Status bar color. -->
    <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
    <!-- Customize your theme here. -->
</style>

注意:设置colorPrimaryVariant
