我该怎么做

推荐答案

编写一种将Color转换为String的方法.

Write a method to convert a Color to a String.

HTML颜色代码只是将R，G和B值转换为十六进制，并显示为前面带有井号的字符串.这是一种相当简单的编写方法.

An HTML color code is just the R, G, and B values converted to hex and displayed as a string with a pound sign in front. This is a fairly simple method to write.

public static String toHexString(Color c) {
  StringBuilder sb = new StringBuilder("#");

  if (c.getRed() < 16) sb.append('0');
  sb.append(Integer.toHexString(c.getRed()));

  if (c.getGreen() < 16) sb.append('0');
  sb.append(Integer.toHexString(c.getGreen()));

  if (c.getBlue() < 16) sb.append('0');
  sb.append(Integer.toHexString(c.getBlue()));

  return sb.toString();
}
