要改变上面棒棒糖的颜色，只需将其添加到您的styles.xml中

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

但是请记住，如果你想让状态栏有一个浅色，也可以添加这一行

<item name="android:windowLightStatusBar">true</item>

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)

在Values中的colors.xml中将colorPrimary编辑为你想要的状态栏的颜色。例如:

   <resources>
<color name="colorPrimary">#800000</color> // changes the status bar color to Burgundy
<color name="colorPrimaryDark">#303F9F</color>
<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>

若要更改状态栏的颜色，请转到 Res /values-v21/styles.xml和状态栏的颜色

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light">
        <item name="colorPrimary">@color/color_primary</item>
        <item name="colorPrimaryDark">@color/color_secondary</item>
        <item name="colorAccent">@color/color_accent</item>
        <item name="android:statusBarColor">#0000FF</item>
    </style>
</resources>

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>

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>
