java 从字符串输入获取颜色

Getting a Color from a String input

提问by Tom

I am making an application where at some point i need the user to select a color, but as to not just have 50 radioButtons, I was wondering if it is possible to actually get the color they want from a textfield or something.

我正在制作一个应用程序，在某些时候我需要用户选择一种颜色，但不仅仅是有 50 个单选按钮，我想知道是否有可能从文本字段或其他东西中实际获得他们想要的颜色。

Wouldn't it be easier to just make a JComboBox or something alike?

制作 JComboBox 或类似的东西不是更容易吗？

But to answer your question: Yes it is possible. I'll give a piece of code that you could use as a start to get you going (assuming you still want the string to color)

但是要回答您的问题：是的，这是可能的。我将给出一段代码，您可以将其用作开始（假设您仍然希望字符串着色）

String text = "red";
Color color;
Field field = Class.forName("java.awt.Color").getField(text.toLowerCase()); // toLowerCase because the color fields are RED or red, not Red
color = (Color)field.get(null);

尝试

Color aColor   = (Color) Color.class.getField("white").get(null);

See if the static method Color.decode()will serve your purpose.
