Android工作室：顶部栏图标上的白色空间

Question

在Android Studio上测试我的应用时似乎遇到了一个小问题。每当我在模拟器上运行我的应用程序时，总会显示一个白色条代替顶部栏图标（电池，时间等）。我不确定这个问题是什么，但下面显示了我的问题和logcat结果的屏幕截图：

Answer 1

如果你仔细观察，它不仅仅是一个白色的酒吧。状态栏颜色设置为白色。你可以看到所有的图标。所以改变颜色，

SELECT

或者，在主题中，更改将用作状态栏颜色的Window window = activity.getWindow(); // clear FLAG_TRANSLUCENT_STATUS flag: window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); // add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); // finally change the color window.setStatusBarColor(YOUR_COLOR); 。

注意：此方法在API级别21中添加。

Answer 2

从Android 5.0开始，状态栏与ActionBar分开着色。确保您未在​​基本主题中将android:statusBarColor设置为@color/white。
