从要更改状态栏颜色的活动调用方法。

blackIconStatusBar(this, R.color.white);

方法定义

public static void blackIconStatusBar(Activity activity, int color) {

    activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
    activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
    activity.getWindow().setStatusBarColor(ContextCompat.getColor(activity, color));
}

只需在res/values/styles.xml中创建一个新主题，在其中更改状态栏的颜色“colorPrimaryDark”:

<style name="AppTheme.GrayStatusBar" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimaryDark">@color/colorGray</item>
</style>

并在AndroidManifest.xml中修改活动主题为您想要的，在下一个活动中，您可以通过选择原始主题将颜色更改回原始主题:

<activity
    android:name=".LoginActivity"
    android:theme="@style/AppTheme.GrayStatusBar" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

这就是res/values/colors.xml应该看起来的样子:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#3F51B5</color>
    <color name="colorPrimaryDark">#303F9F</color>
    <color name="colorAccent">#c6d6f0</color>
    <color name="colorGray">#757575</color>
</resources>

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)
    }

放置这是你的values-v21/styles.xml，在棒棒糖上启用它:

<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">@color/color_primary</item>
    </style>
</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>

在kotlin中，我能够使用以下方法解决这个问题:

  window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
  window.statusBarColor = ContextCompat.getColor(this, android.R.color.transparent)
