这就是我在奇巧(KitKat)的做法，而且效果不错。

public static void setTaskBarColored(Activity context) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
        {
            Window w = context.getWindow();
            w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            //status bar height
            int statusBarHeight = Utilities.getStatusBarHeight(context);

            View view = new View(context);
            view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
            view.getLayoutParams().height = statusBarHeight;
            ((ViewGroup) w.getDecorView()).addView(view);
            view.setBackgroundColor(context.getResources().getColor(R.color.colorPrimaryTaskBar));
        }
    }

一个非常非常古老的问题。但是对于那些想要改变状态栏颜色从ANDROID 5.0, API 21及以上根据主题暗和光甚至设备默认。 把这段代码放在你的活动super.onCreate(savedInstanceState)之后;setContentView(r.b ayout.activity_main);

int currentNightMode = getResources().getConfiguration().uiMode & Configuration.UI_MODE_NIGHT_MASK;
    switch (currentNightMode) {
        case Configuration.UI_MODE_NIGHT_NO:
            // Night mode is not active on device
            // For WHITE status bar Icons color to dark
            Window window = getWindow();
            View view = window.getDecorView();
            new WindowInsetsControllerCompat(window, view).setAppearanceLightStatusBars(true);
            break;
        case Configuration.UI_MODE_NIGHT_YES:
            // Night mode is active on device
            break;
    }

也符合你的风格。Xmlput这行 <项目名称= " android: statusBarColor " > @color / colorWhite > < /项目

在values/theme.xml中，添加命名为name="android:statusBarColor"的项。

 <resources xmlns:tools="http://schemas.android.com/tools">
        <style name="Theme.YourAppName" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
            ...
            ...
            ...
            <!-- Status bar color. -->
            <item name="android:statusBarColor" tools:targetApi="l">@color/purple_700</item>
        </style>
    </resources>

您可以使用此功能更改状态栏的颜色。适用于android L意味着API 21及更高，需要一个颜色字符串，如“#ffffff”。

private void changeStatusBarColor(String color){
    if (Build.VERSION.SDK_INT >= 21) {
        Window window = getWindow();
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.setStatusBarColor(Color.parseColor(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>
