问题描述

我尝试AppCompat的棉花糖。而且我希望有一个透明的状态栏然而，它变成白色。我试了几个解决方案，但他们并没有为我工作（<一href="http://stackoverflow.com/questions/28289477/transparent-status-bar-not-working-with-windowtranslucentnavigation-false">Transparent状态栏不工作windowTranslucentNavigation =＆QUOT;假＆QUOT; ，<一个href="http://stackoverflow.com/questions/27856603/lollipop-draw-behind-statusbar-with-its-color-set-to-transparent">Lollipop ：画背后的状态栏。它的颜色设置为透明）。下面是相关的code。

I am trying out AppCompat on Marshmallow. And I want to have a transparent status bar however it turns white. I've tried a couple solutions but they didn't work for me (Transparent status bar not working with windowTranslucentNavigation="false", Lollipop : draw behind statusBar with its color set to transparent). Here's related code.
