String s="19831014\n"+"linknum"+i+"cool";

"\n" is a line break.

String doesnot have Color but the thing that displays a String has.

But you can convert your String object to SpannableString which allows user to add effects like Bold, italics, Underline, Colored Text Portions etc.

if you want to display String with different colors you have to use ForegroundColorSpan

For example :

 SpannableString colouredString =new SpannableString("Red, Green, Blue.");

 colouredString.setSpan(new  ForegroundColorSpan(0xFFFF0000), 0, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 colouredString.setSpan(new ForegroundColorSpan(0xFF00FF00), 5, 11, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 colouredString.setSpan(new ForegroundColorSpan(0xFF0000FF), 12, colouredString.length() - 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

For changing the Background Color you have to use BackgroundColorSpan :

For Example :

coloredString.setSpan(new BackgroundColorSpan(0xFFFFFF00), 8, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

now you can use this colouredString for showing it in EditText and TextView

For giving different styles you can use StyleSpan
