How do i space getString words?

Question

I have the following code, and i want to have a toast message that says "Congratulations nameToasted, you made 5 points!" but i get "CongratulationsnameToasted, you made5points!". i have already tried spacing on the strings.xml, but nothing.

String pointsInMessage = getString(R.string.congratulations) + nameToasted;
pointsInMessage = pointsInMessage + getString(R.string.you_made);
pointsInMessage = pointsInMessage + pointsPerAnswer;
pointsInMessage = pointsInMessage + getString(R.string.points_string) ;

You should add empty spaces, between concatenations. Even better, use a StringBuilder. As an alternative, you could join an array of strings using a space as the joining character. — Phantômaxx, Aug 23 '17 at 16:44

Try with String.format(), something like following:

final String pointsInMessage = String.format("%s %s, %s %d %s!", getString(R.string.congratulations), nameToasted, getString(R.string.you_made), pointsPerAnswer, getString(R.string.points_string));

Assuming that pointsPerAnswer is an Integer.

Do it like that:

String pointsInMessage = getString(R.string.congratulations) +" "+nameToasted;

getString() always returns the string with .trim() applied so you can't use trailing and leading spaces in the strings.xml file.

Here is an example of a string builder you can use:

StringBuilder sb = new StringBuilder();
sb.append(R.string.congratulations).append(" ")
  .append(nameToasted).append(R.string.you_made).append(" ") 
  .append(pointsPerAnswer).append(" ").append(R.string.points_string);
String message = sb.toString();

this should give you the message you want to display.
