采用HSV生成随机颜色
使用hsv/hsb生成随机颜色,并排除靠近黑白两色的色值
public static String randomColor(){ int max = 25500000 ; Random rand = new Random(); int r = rand.nextInt(max); int b = rand.nextInt(max); int g = rand.nextInt(max); float h = r % 360.0f; float s = g % 180 / 360.0f + 0.5f; float v = b % 180 / 360.0f + 0.5f; float[] hsv = new float[]{h,s,v}; // h- 0...360 s-0...1 v-0...1 System.out.println("颜色 : "+"h="+h+",s="+s+",v="+v + " , argb=" + Color.HSVToColor(0x88, hsv)); return Color.HSVToColor(0x88, hsv)+""; }
注意:可直接返回整形,使用直接用setColor(int color)
