常规状态栏需要兼容魅族、小米、6.0的黑字，也有人另辟蹊径，给状态栏强行变深，假如你制定白色，那么就会被转化成灰色，下面是转化代码

private static int calculateStatusColor(@ColorInt int color, int alpha) {//112
    if (alpha == 0) {
        return color;
    }
    float a = 1 - alpha / 255f;
    int red = color >> 16 & 0xff;
    int green = color >> 8 & 0xff;
    int blue = color & 0xff;
    red = (int) (red * a + 0.5);
    green = (int) (green * a + 0.5);
    blue = (int) (blue * a + 0.5);
    return 0xff << 24 | red << 16 | green << 8 | blue;
}
