I searched many places, and the only solution I found was SimonVT's Pickers.
我搜索了很多地方，我找到的唯一解决方案是 SimonVT 的 Pickers。
After implementing the library, it was very easy to change the colors. In numberpicker- the library uses images that can be simply replaced with the desired designs.
实现库后，更改颜色非常容易。在 numberpicker 中，库使用可以简单地替换为所需设计的图像。
This example has three pickers: NumberPicker, DatePicker and TimerPicker.
此示例具有三个选择器：NumberPicker、DatePicker 和 TimerPicker。

Did you ever figure out how to change the divider color? I'm trying to do the same thing and can't really find anything at the moment.
你有没有想过如何改变分隔线的颜色？我正在尝试做同样的事情，目前无法真正找到任何东西。
