Get color-int from alpha, red, green, blue components

Android system's android.graphics.Color class provide methods for creating and converting color ints.

• public static int argb (int alpha, int red, int green, int blue)
  Return a color-int from alpha, red, green, blue components. These component values should be [0..255], but there is no range check performed, so if they are out of range, the returned color is undefined.
• public static int rgb (int red, int green, int blue)
  Return a color-int from red, green, blue components. The alpha component is implicity 255 (fully opaque). These component values should be [0..255], but there is no range check performed, so if they are out of range, the returned color is undefined.
