我正在处理透明的状态栏和底部导航栏。我在上一个问题：Gradient status bar with BottomNavigationView
中也取得了相同的成绩但是现在，我有一个片段，其中
fitsSystemWindows不是 工作。我有像活动-> Viewpager->片段->这样的布局 Viewpager->子片段。
我已经经历了很多堆栈溢出的尝试，但是仍然没有运气：
我添加了此样式：
<item name="android:windowContentOverlay">@null</item>
<item name="windowActionBarOverlay">true</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
<item name="android:windowTranslucentNavigation">false</item>
<item name="android:navigationBarColor">#000</item>
<item name="colorControlNormal">#FFFFFF</item>
<item name="colorPrimaryDark">@android:color/transparent</item>
在v21 /样式中：
<item name="colorPrimaryDark">@android:color/transparent</item>
在布局中，我向每个片段和活动都添加了fitsSystemWindows。
活动布局：
