制作Android应用程序（随机颜色）

Question

What I need to do is an application that when you click on the screen it will just show random colours on the screen; press the screen again and you will get other random colours (colours that are not only Red, Blue, Green).

Answer 1

If you need only bright, saturated colors, use Color.HSVToColor() instead of setting R, G and B components directrly:

float[] hsvColor = {0, 1, 1};
// randomly generate only hue component,
// leaving saturation and brightness maximum possible
hsvColor[0] = new Random().nextFloat() * 360;
view.setBackgroundColor(Color.HSVToColor(hsvColor));
