AppBarLayout fitsSystemWindows true attr 使 CircularIndicator 不可见

Question

我在下面给出的个人资料页面中使用 Jake Wharton 的 CirclePageIndicator。

图像容器是一个 viewpager，circlepage 指示器显示在它的底部。

而且我需要将 appbar 的 fitsSystemWindows 属性设置为 true 才能使 statusbarscrim 正常工作。但是当使用这个属性时 circlePagerIndicator 消失了。

提前感谢您的帮助 ;)

AppBarLayout android:fitsSystemWindows="true" 以某种方式使其与 CollapsingToolbarLayout 内的 RelativeLayout 混淆。似乎有一个错误。所以我删除了它，它就像一个魅力。
