上一篇我们说了第一种沉浸式状态栏实现方式，但其实现虽然可以满足大部分需求了，发现对于接入swipebacklayout（仿微信侧滑返回）状态栏不会跟随界面滑动，得等到界面退出后才改变状态栏颜色。现在我们通过直接设置状态栏透明，然后手动在添加一个伪状态栏来实现。此伪状态栏非第一种实现方式的伪状态栏（文字描叙起来还是比较抽象，可以看下面布局图）

看图写代码O(∩_∩)O，先看效果图，否则说我瞎忽悠

咱还是挺实诚的，看效果还是挺不错的。

当然，还是得给伪状态栏及我们手动加上的LinearLayout设置id（在values下新建一资源文件ids），否则对于多Fragment的同一Activiy跟随其变化状态栏方便找到对应View进行修改。
