java - int argb 颜色输出奇怪值

Question

我正在尝试创建使用随机颜色的小型应用程序。

Random rnd = new Random();
        int color1 = Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256));
        int color2 = Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256));
        int color3 = Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256));

但在color1、color2、color3中保存了诸如“-11338194”之类的值。是否可以取argb值？ (比如“255255255255”什么的)谢谢!

Answer 1

试试这段代码，

Random rnd = new Random();
        int color1 = Color.argb(255, rnd.nextInt(256 - 0), rnd.nextInt(256 - 0), rnd.nextInt(256 - 0));
        int color2 = Color.argb(255, rnd.nextInt(256 - 0), rnd.nextInt(256 - 0), rnd.nextInt(256 - 0));
        int color3 = Color.argb(255, rnd.nextInt(256 - 0), rnd.nextInt(256 - 0), rnd.nextInt(256 - 0));
