解决方案

好像这个解决方案很简单

您

 安卓fitsSystemWindows =真

在片段CoordinateLayoutView

从这里取出并放在在活动的根本看法。

这应该现在所有的工作

EDIT of 23/7/2015: Support Design Library v22.2.1 didn't fix :-( Also this happens on toolbar quick return on MainActivity!

EDIT of 28/7/2015: Linked question: CoordinatorLayout status bar padding disappears during fragment transactions

From example repository https://github.com/chrisbanes/cheesesquare I've implemented the ViewPager on Detail Activity. It works, but the StatusBar disappears from 2nd page as you see in the picture only in Lollipop devices, Any idea?I use android:fitsSystemWindows="true" but it does work only on first page :-(

activity_detail_viewpager.xmlif I put here fitsSystemWindows, StatusBar is not transparent anymore, but it works (status bar padding is not lost). But I would like it transparent!

解决方案

Seems the solution for this is simple

You have 

android:fitsSystemWindows="true"

In the fragment CoordinateLayoutView

remove it from here and put in the Activity's root view.

This should now all work
