[置顶] android白色背景状态栏字体颜色

改变状态栏颜色的仿佛只能用于小米，魅族，已经6.0以上的手机，vivo系统源码不开发，所以没办法修改，直接上代码

小编发现一个小问题，就是对于华为有下部虚拟导航栏的手机来说说，可能会江虚拟导航栏变成白色或者透明四，最好最后把BarTextColorUtils中的activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);注掉试试

或者大家也可收索一下全局，能不能搜索到FLAG_TRANSLUCENT_NAVIGATION这个字段，不要把底部设置为透明就可以了，由于我身边没有手机，所以这仅仅作为提示
