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)
    }

如果你想在Android 4.4及以上版本上工作，试试这个。我参考了Harpreet的答案和这个链接。Android和透明的状态栏

首先，在Activity的onCreate方法中调用setStatusBarColored方法(我把它放在util类中)。我在这里用了一张图片，你可以用颜色来改变它。

public static void setStatusBarColored(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);
        int statusBarHeight = 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.setBackground(context.getResources().getDrawable(R.drawable.navibg));
    }
}

public static int getStatusBarHeight(Activity context) {
    int result = 0;
    int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = context.getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}

后:

状态栏的颜色已经改变了，但是导航栏被切断了，所以我们需要在onCreate方法中设置导航栏的边距或偏移量。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT, (int)(this.getResources().getDimension(R.dimen.navibar_height)));
        layoutParams.setMargins(0, Utils.getStatusBarHeight(this), 0, 0);

        this.findViewById(R.id.linear_navi).setLayoutParams(layoutParams);
    }

然后状态栏将是这样的。

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

我有这样的需求:通过编程方式改变状态栏的颜色，使其保持透明，以允许导航抽屉绘制自己与透明的状态栏重叠。

我不能用API来做这个

getWindow().setStatusBarColor(ContextCompat.getColor(activity ,R.color.my_statusbar_color)

如果你在stack overflow中检查这一行代码之前的所有人，将状态栏的透明度设置为solid with

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)

我能够像这样管理状态栏的颜色和透明度:

Android 4: there's not much you can do, because you can't manage status bar color from the API ... the only thing you can do is to set the status bar as translucent and move a colored element of you UI under the status bar. To do this you need to play with android:fitsSystemWindows="false" in your main layout. This allows you to draw you layout under the status bar. Then you need to play with some padding with the top of your main layout. Android 5 and above: you have to define a style with <item name="android:windowDrawsSystemBarBackgrounds">true</item> <item name="android:statusBarColor">@android:color/transparent</item> this allows the navigation drawer to overlap the status bar. Then to change the color keeping the status bar transparent you have to set the status bar color with drawerLayout.setStatusBarBackgroundColor(ContextCompat.getColor(activity, R.color.my_statusbar_color)) where drawerLayout is defined like this <android.support.v4.widget.DrawerLayout android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true">

好吧，Izhar的解决方案是可以的，但就我个人而言，我尽量避免这样的代码:

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
//Do what you need for this SDK
};

但我也不喜欢重复代码。在你的回答中，我必须在所有活动中添加如下一行代码:

setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));

因此，我采用了Izhar的解决方案，并使用XML得到了相同的结果: 为StatusBar status_bar.xml创建一个布局

<View xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="@dimen/statusBarHeight"
     android:background="@color/primaryColorDark"
     android:elevation="@dimen/statusBarElevation">

注意height和elevation属性，这些设置在values中，values-v19, values-v21再往下。

使用include main_activity.xml将这个布局添加到你的活动布局中:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/Black" >

<include layout="@layout/status_bar"/>
<include android:id="@+id/app_bar" layout="@layout/app_bar"/>
//The rest of your layout       
</RelativeLayout>

对于工具栏，添加top margin属性:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="@color/primaryColor"
app:theme="@style/MyCustomToolBarTheme"
app:popupTheme="@style/ThemeOverlay.AppCompat.Dark"
android:elevation="@dimen/toolbarElevation"
android:layout_marginTop="@dimen/appBarTopMargin"
android:textDirection="ltr"
android:layoutDirection="ltr">

< / android.support.v7.widget.Toolbar >

在你的appTheme样式-v19.xml和样式-v21.xml中，添加window半透明attr:

styles-v19.xml v21:

<resources>
<item name="android:windowTranslucentStatus">true</item>
</resources>

最后，在你的维度上，dimensions -v19, dimensions -v21，添加工具栏topMargin的值，以及statusBarHeight的高度: 小于KitKat的:

<resources>
<dimen name="toolbarElevation">4dp</dimen>
<dimen name="appBarTopMargin">0dp</dimen>
<dimen name="statusBarHeight">0dp</dimen>
</resources>

状态栏的高度总是24dp 维-v19.xml的奇巧和以上:

<resources>
<dimen name="statusBarHeight">24dp</dimen>
<dimen name="appBarTopMargin">24dp</dimen>
</resources>

如果需要，只需要添加抬高:

<resources>
<dimen name="statusBarElevation">4dp</dimen>
</resources>

这是Jellybean KitKat和Lollipop的结果:

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>
