Question

Sorry for such a simple question, but how would you put a space between a random number that is being generated and then sent to setText?

It now displays ########, but I want it to display as #### ####

text = (TextView) findViewById(R.id.tv_randnumber);
text.setText(String.valueOf((int) (Math.random() * 100000000)));

Answer 1

I suggest this:

text = (TextView) findViewById(R.id.tv_randnumber);
String random = String.valueOf((int) (Math.random() * 100000000));
String one = random.substring(0, 4);
String two = random.substring(4, 8);
text.setText(one + " " + two);

This must work.
