How can i convert color code in integer ex: 13369395 to android specific. Since 13369395 is also an integer i tried doing
mainLayout.setTextColor(13369395);
but its not working.
I also tried converting 13369395 to hexadecimal like:
mainLayout.setBackgroundColor(Integer.parseInt(13369395 +"", 16)+0xFF000000);
but it also didn't help.

I got the solution. Just a work around with Hexadecimal as below:
Integer.toHexString(colour);
Which returns the hexadecimal string for your integer, again if you just use it by
mainLayout.setBackgroundColor(Integer.parseInt(hexVal,16));
it wont work. You need to add mask as
mainLayout.setBackgroundColor(0xff000000 + Integer.parseInt(hexVal,16));
This has resolved the problem

Try passing:
mainLayout.setBackgroundColor(Color.parseColor("#FFFFFF"));

The question is very old. But still I found this answer would help someone who search a way to set the color directly as integer.
If you look at the android documentation, the constant value for white is -1 and black is -16777216. (i.e.) the whole color int value range is (-1 to -16777216). So you can simply add the integer value to -16777216.
For example if you want to set color white whose decimal representation is 16777215 (0xffffff), then 16777215 - 16777216 will give you -1 the color constant for black in android.

You can directly take hexadecimal code.For example
mainLayout.setBackgroundColor( #0BB5FF);
