你可以使用这段简单的代码:

Kotlin中的一行代码:

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

原始答案与Java和手动版本检查:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light, this.getTheme()));
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light));
}

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>

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

<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

如果你想通过编程方式改变状态栏的颜色(前提是设备有Android 5.0)。 这是一个简单的方法来改变statusBarColor从任何活动 和非常简单的方法，当不同的片段有不同的状态栏颜色。

 /**
 * @param colorId id of color
 * @param isStatusBarFontDark Light or Dark color
 */
fun updateStatusBarColor(@ColorRes colorId: Int, isStatusBarFontDark: Boolean = true) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        val window = window
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        window.statusBarColor = ContextCompat.getColor(this, colorId)
        setSystemBarTheme(isStatusBarFontDark)
    }
}

/** Changes the System Bar Theme.  */
@RequiresApi(api = Build.VERSION_CODES.M)
private fun setSystemBarTheme(isStatusBarFontDark: Boolean) {
    // Fetch the current flags.
    val lFlags = window.decorView.systemUiVisibility
    // Update the SystemUiVisibility depending on whether we want a Light or Dark theme.
    window.decorView.systemUiVisibility = if (isStatusBarFontDark) lFlags and View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR.inv() else lFlags or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
}

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));
        }
    }
