将colorPrimaryDark更改为您想要的颜色到res/values/styles.xml文件中

    <resources>
        <color name="colorPrimary">#800000</color>
        <color name="colorPrimaryDark">#303F9F</color> //This Line
        <color name="colorAccent">#FF4081</color>
        <color name="red">#FF0000</color>
        <color name="white">#FFFFFF</color>
       <color name="cream">#fffdd0</color>
       <color name="burgundy">#800000</color>
    </resources>

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));
}

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));
    }
}

<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

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>

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">
