在Values中的colors.xml中将colorPrimary编辑为你想要的状态栏的颜色。例如:

   <resources>
<color name="colorPrimary">#800000</color> // changes the status bar color to Burgundy
<color name="colorPrimaryDark">#303F9F</color>
<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>

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));
}

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>

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>

只需在styles.xml文件中添加这些行

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- This is used for statusbar color. -->
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <!-- This is used for statusbar content color. If statusbarColor is light, use "true" otherwise use "false"-->
    <item name="android:windowLightStatusBar">false</item>
</style>

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));
        }
    }
