java - How can I format a String number to have commas in android Edit Field

Question

For what function I can use in android to display the number into different formats.

For eg: If I enter 1000 then it should display like this 1,000. If I enter 10000 then it should display like this 10,000. If I enter 1000000 then it should display like this 1,000,000.

Please guide me.

Answer 1

You could use DecimalFormat and just format the number

DecimalFormat formatter = new DecimalFormat("#,###,###");
String yourFormattedString = formatter.format(100000);

The result will be

• 1,000,000 for 1000000
• 10,000 for 10000
• 1,000 for 1000

This String.format("%,d", number) would be a better(less hardcoded) solution as indicated in the comments below by @DreaminginCode so I thought I would add it here as an alternative
