现在沉浸式状态栏基本都成为产品主流样式了。但对于google官方提供的API对于状态栏的颜色设置是4.4版本才推出，所以我们也只能适配4.4及以上版本。但在4.4到5.0的时候只能通过设置状态栏透明，然后手动添加伪状态栏来进行修改状态栏颜色，对于5.0以上可以通过修改状态栏颜色即可。我们都知道，对于Activity我们通过setContentView方法添加的我们需要显示的xlm布局文件，其实是添加在decoview下面的content（其实是一个FrameLayout）里面。对于4.4~5.0之间的版本我们创建的伪状态栏就添加在decoview里面。先看看效果：

statusbarutils02.png
看效果还行，并且以适配Drawlayout，Fragment对状态栏的修改。
如果对于文字描叙不太清楚，可看看下面实现方式布局图：

废话不多，开撸、开撸。

为了在Fragment切换时修改同一Activity的状态栏，所以我们得给伪状态栏设置id（及在values目录下新建一资源文件ids）
<item name="status_bar_util_fake_status_bar_view" type="id" />
