注：虽然原生系统从4.4开始，就支持状态栏颜色修改，但因原生6.0以下系统不支持状态栏图标颜色的修改，故此处只讨论6.0以上的处理。
一、修改方案
第一种，设置主题
-
values-23目录下，添加style
其中，主要代码：
- @color/white
- true
// true：图标为深色；false：图标为浅色
-
清单文件引用
-
同样，Dialog也可引用
AlertDialog.Builder alert = new AlertDialog.Builder(activity, R.style.BaseTheme)
第二种，代码动态设置
public void setStatusBarColor(String color, boolean isDark) {
try {
int colorInt = Color.parseColor(color);
setStatusBarColor(colorInt, isDark);
} catch (Exception e) {
}
}
public void setStatusBarColor(int color, boolean isDark) {
// set statusbar icon color
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {// 注：此处实际应区分4.4以上、5.0、6.0以上，进行不同的处理
String osName = "Other";
if (MIUISetStatusBarLightMode(this, isDark)) {
osName = "MIUI";
} else if (FlymeSetStatusBarLightMode(this, isDark)) {
osName = "Flyme";
}
// 以下为原生6.0设置状态栏深/浅色主题的代码。此处因MIUI在Android 6.0 、开发版 7.7.13 及以后版本已舍弃自家的方案，故这里没有分else，而是调用原生方法再次对状态栏图标颜色进行设置。PS：经测试，Flyme没有此问题。
int ui = getWindow().getDecorView().getSystemUiVisibility();
if (isDark) {
ui |= View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR;
} else {
ui &= ~View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR;
}
getWindow().getDecorView().setSystemUiVisibility(ui);
getWindow().setStatusBarColor(color);
}
}

二、踩坑
在小米设配上，如果Dialog为全屏显示，状态栏颜色会受Dialog主题影响，而非原来Activity设置的颜色。这时需要在创建Dialog的时候重新设置一下，代码如下：
// set MIUI status bar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
dialog.getWindow().setStatusBarColor(Color.WHITE);
MIUISetStatusBarLightMode(dialog.getWindow(), true);
}
dialog.show();
