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);

放置这是你的values-v21/styles.xml，在棒棒糖上启用它:

<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">@color/color_primary</item>
    </style>
</resources>

Android 5.0棒棒糖引入了材质设计主题，根据主题的colorPrimaryDark值自动为状态栏上色。

realdognose注意:在材质设计库中，它将是colorPrimaryVariant

由于从版本21开始的support-v7-appcompat库，设备pre-lollipop支持这一点。Chris Banes关于支持appcompat v21的博文

在kotlin中，我能够使用以下方法解决这个问题:

  window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
  window.statusBarColor = ContextCompat.getColor(this, android.R.color.transparent)

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));
}

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));
        }
    }
