現(xiàn)在沉浸式狀態(tài)欄基本都成為產(chǎn)品主流樣式了瓤逼。但對(duì)于google官方提供的API對(duì)于狀態(tài)欄的顏色設(shè)置是4.4版本才推出毅人，所以我們也只能適配4.4及以上版本闯狱。但在4.4到5.0的時(shí)候只能通過(guò)設(shè)置狀態(tài)欄透明票堵，然后手動(dòng)添加偽狀態(tài)欄來(lái)進(jìn)行修改狀態(tài)欄顏色，對(duì)于5.0以上可以通過(guò)修改狀態(tài)欄顏色即可偷溺。我們都知道蹋辅，對(duì)于Activity我們通過(guò)setContentView方法添加的我們需要顯示的xlm布局文件，其實(shí)是添加在decoview下面的content（其實(shí)是一個(gè)FrameLayout）里面挫掏。對(duì)于4.4~5.0之間的版本我們創(chuàng)建的偽狀態(tài)欄就添加在decoview里面侦另。先看看效果：

看效果還行，并且以適配Drawlayout，F(xiàn)ragment對(duì)狀態(tài)欄的修改褒傅。
如果對(duì)于文字描敘不太清楚弃锐，可看看下面實(shí)現(xiàn)方式布局圖：

為了在Fragment切換時(shí)修改同一Activity的狀態(tài)欄，所以我們得給偽狀態(tài)欄設(shè)置id（及在values目錄下新建一資源文件ids）
