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.

Solution 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

Update 12/02/2019

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

Solution 2

try this one hope it will help.

 System.out.println(NumberFormat.getNumberInstance(Locale.US).format(1000));

Solution 3

private String getFormatedAmount(int amount){
  return NumberFormat.getNumberInstance(Locale.US).format(amount);
}

Solution 4

int[] numbersToFormat = new int[]
  { 1, 10, 100, 10000, 100000, 1000000, 10000000, 100000000, 1000000000 };


for (int number : numbersToFormat) {
  System.out.println(  
    NumberFormat.getNumberInstance(Locale.getDefault()).format(number));
}

OUTPUT

1
10
100
10,000
100,000
1,000,000
10,000,000
100,000,000
1,000,000,000

Solution 5

Add this function in common class

  public static String getFormatedNumber(String number){
        if(!number.isEmpty()) {
            double val = Double.parseDouble(number);
            return NumberFormat.getNumberInstance(Locale.US).format(val);
        }else{
            return "0";
        }
    }

And use that function every where like this:

String newNumber = Utils.getFormatedNumber("10000000");

but if i enter 100000 it displaying 100,000 instead i need like this 1,00,000, is it possible?

Why would you want to do that? 100,000 is standard. Try moving the comma in the hash format like this #,##,###. Don't know if it will work but you can give it a try.

[Matt]

To be safe, you'll likely want to use the device's locale, not always US. Locale current = getResources().getConfiguration().locale;

[Gober]

Locale.getDefault() is an even easier way to get device locale.

[Juan De la Cruz]

According to Java Documentation, parameterless get...Instance() methods use default locale by default.

[gonephishing]

@Neil, the standard is only valid for specific countries. Like for example, India has a different standard and is of the format #,##,###

[Hai Zhang]

Not to mention countries using dot . as thousands separator. This is such a bad but popular hard-coding answer. Developers should always respect user's locale unless there's a very good reason for not doing so.

[the-ginger-geek]

@dreamingincode this answer, answers the question. If the question gave more insight into the actual problem the answer might have been different. It is not my place to judge good or bad practice with insufficient information. Practice can only be judged in practice. I agree that using locale would be a better solution if the application was to be used world wide.

[Hai Zhang]

It answers the question but answering a question doesn't automatically make it a good answer. And when information is insufficient, I believe one as a programmer should assume less instead of more. Answers that use hard-coding can break easily when assumptions change, and in this case hard-coding is especially bad for any i18n related code because there can always be future people trying to add i18n and it would be their wtf moment. Not to mention even just a larger number can break this. For a much simpler solution, you could have used String.format("%,d", number) which is short and correct

can I add decimal behind like 1,000,000.50 ? Or 1M.50 ? @Neil
