谷歌地图自定义样式 - 饱和度，亮度不起作用答案

【问题标题】：google maps custom styling - saturation, lightness do not work谷歌地图自定义样式 - 饱和度，亮度不起作用
【发布时间】：2017-11-16 08:19:38
【问题描述】：

我正在尝试使用 google maps android sdk 在 android 上使用自定义地图样式。大多数更改和自定义样式正在设置和工作中。但是在图标上设置饱和度或亮度不起作用 - 如果我尝试在图标（poi、labels.icon）上设置饱和度或亮度，那么图标会完全消失。

删除饱和度和亮度值会导致图标再次出现。

json 是从 google maps 样式向导 (https://mapstyle.withgoogle.com) 生成的。

这是我使用的确切 json：
