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

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));
    }
}

还有一个解决方案:

final View decorView = w.getDecorView();
View view = new View(BaseControllerActivity.this);
final int statusBarHeight = UiUtil.getStatusBarHeight(ContextHolder.get());
view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, statusBarHeight));
view.setBackgroundColor(colorValue);
((ViewGroup)decorView).addView(view);

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>

解决方法很简单，把下面的代码放到style.xml中

对于黑暗模式:

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