How to format longs in android to always display two digits

You can accomplish it with DecimalFormat:

NumberFormat f = new DecimalFormat("00");long time = 9;textView.setText(f.format(time));

Output:

Or you can use String.format() as well:

String format = "%1$02d"; // two digitstextView.setText(String.format(format, time));

java android formatting

Use: text.setText(String.format("%02d", i)); where i is the integer value

java android formatting

Why not just use an if statement?

String str = x < 10 ? "0" + String.valueOf(x) : String.valueOf(x);

That should do the trick.
