Unable to parse ARGB hex to integer

Question

I'm trying to parse an ARGB hex String to an int but it's not working.

My code:

int color = Integer.parseInt("ff686868", 16);

Exception:

java.lang.NumberFormatException: unable to parse 'ff686868' as integer
at java.lang.Integer.parse(Integer.java:438)
at java.lang.Integer.parseInt(Integer.java:422)
...

When I try to parse a normal RGB String like 686868 it does work but when I add the alpha it breaks down. I hope someone can help me.

Answer 1

The number would be too big for integer.

Use: Long.parseLong(..)

Answer 2

使用java.lang.Long.parseLong() - int是带符号的，因此它只有31位+ 1个符号位，并且全部使用4 * 8 = 32位。

Answer 3

您可以使用Color.parseColor(String)来获取int

Answer 4

Color.parseColor(String);

如果itz hexacode这样做

Color.parseColor("#ffffff");
