问题描述
2016 年 1 月 2 日 应通过应用 Android 团队提供的代码解决错误:https://stackoverflow.com/a/35132144/3397345，请参阅下面接受的答案.
EDIT of 01/02/2016: Bug should be resolved by applying the code provided by Android Team: https://stackoverflow.com/a/35132144/3397345, see accepted answer below.
27/01/2016 在 v23.1.1 中仍未解决错误.到目前为止提供的解决方案不提供透明状态栏(这是此布局的目的)或过于复杂.此处提供了该错误的新屏幕记录:https://www.youtube.com/watch?v=76IxhlUx8MQ
EDIT of 27/01/2016: Bug still not resolved in v23.1.1. Solutions provided until now don't give transparent status bar (which is the purpose of this layout) or are too complex. A new screen-record of the bug available here: https://www.youtube.com/watch?v=76IxhlUx8MQ
23/07/2015 支持设计库 v22.2.1 未修复 :-(这也发生在 MainActivity 的工具栏快速返回上！
EDIT of 23/07/2015: Support Design Library v22.2.1 didn't fix :-( Also this happens on toolbar quick return on MainActivity!
28/07/2015 链接问题:CoordinatorLayout 状态栏填充在片段事务期间消失
来自示例存储库 https://github.com/chrisbanes/cheesesquare 我已经实现了详细活动上的 ViewPager.它可以工作，但状态栏从第二页消失，正如您在图片中看到的那样仅在棒棒糖设备中，知道吗?我使用 android:fitsSystemWindows="true" 但它只在第一页有效:-(
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.xml如果我放在这里 fitSystemWindows，StatusBar 不再透明，但它可以工作(状态栏填充不会丢失).但我希望它透明！
activity_detail_viewpager.xml if I put here fitsSystemWindows, StatusBar is not transparent anymore, but it works (status bar padding is not lost). But I would like it transparent!

推荐答案
Android团队在我报告的缺陷的回答中提出的解决方案.这段代码应该终于可以工作了.
Solution proposed by Android Team in the answer of my reported defect. This code should finally work.
ViewPager mViewPager;
ViewCompat.setOnApplyWindowInsetsListener(mViewPager,
new OnApplyWindowInsetsListener() {
@Override
public WindowInsetsCompat onApplyWindowInsets(View v,
WindowInsetsCompat insets) {
insets = ViewCompat.onApplyWindowInsets(v, insets);
if (insets.isConsumed()) {
return insets;
}
boolean consumed = false;
for (int i = 0, count = mViewPager.getChildCount(); i < count; i++) {
ViewCompat.dispatchApplyWindowInsets(mViewPager.getChildAt(i), insets);
if (insets.isConsumed()) {
consumed = true;
}
}
return consumed ? insets.consumeSystemWindowInsets() : insets;
}
});
