Android状态栏黑色字体

###前言

由于公司项目的欢迎页是白色的，，修改状态栏颜色后，导致状态栏的白色字体完全被覆盖了，联想到之前在QQ、UC等一些app上都见到过状态栏的字体是深色的，想着，，必定有解决的方案。于是，有了本篇blog。

###参考下面是我在网上找到的两篇文章

1.白底黑字！Android浅色状态栏黑色字体模式

2.Android-->沉浸式状态栏字体颜色的修改(只针对小米和魅族)

#####2.style属性设置

1<!--直接生效，状态栏文字颜色变成黑色，非沉浸式-->
2<item name="android:windowLightStatusBar">true</item>

结论

本方案适配一下系统

android6.0+

MIUI6

flyme4+

据说：适配浅色状态栏深色字体的时候发现底层版本为Android6.0.1的MIUI7.1系统不支持View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR设置，还是得用MIUI自己的深色字体方法。所以，这里先适配MIUI跟flyme，再适配6.0，当然了，如果使用可以直接获取系统名，根据字符串判断，也可以先6.0在MIUI，但是这个不靠谱。还不如直接在6的系统上统一全配置上

说了这么多废话，，下面进入正题
