How to convert hex to rgb using Java?
How can I convert hex color to RGB code in Java? Mostly in Google, samples are on how to convert from RGB to hex.
我想这应该做到这一点:
/**
*
* @param colorStr e.g. "#FFFFFF"
* @return
*/
public static Color hex2Rgb(String colorStr) {
return new Color(
Integer.valueOf( colorStr.substring( 1, 3 ), 16 ),
Integer.valueOf( colorStr.substring( 3, 5 ), 16 ),
Integer.valueOf( colorStr.substring( 5, 7 ), 16 ) );
}
实际上,这样做有一个更简单(内置)的方法:
Color.decode("#FFCCEE");
public static void main(String[] args) {
int hex = 0x123456;
int r = (hex & 0xFF0000) >> 16;
int g = (hex & 0xFF00) >> 8;
int b = (hex & 0xFF);
}
