Change DecimalFormat locale

Question

I have custom DecimalFormat in Edittext's addTextChangedListener method, everything is working perfectly but when I change language (locale) my addTextChangedListener is not working.

double answer = inputDouble * counterToDouble; DecimalFormat df = new DecimalFormat("##.########"); // df=(DecimalFormat)numberFormat;  df.setRoundingMode(RoundingMode.DOWN); answer = Double.parseDouble(df.format(answer));  unicoinsAmmount.setText(String.valueOf(df.format(answer))); 

I searched about my problem and found a NumberFormat solution:

NumberFormat numberFormat = NumberFormat.getNumberInstance(Locale.US); 

but I don't know how I can use this code.

Answer 1

You can specify locale for DecimalFormat this way:

DecimalFormatSymbols symbols = new DecimalFormatSymbols(Locale.US); DecimalFormat format = new DecimalFormat("##.########", symbols); 

Answer 2

You may try by first converting to NumberFormat and then Cast it to DecimalFormat

Integer vc = 3210000; NumberFormat nf = NumberFormat.getNumberInstance(Locale.US); DecimalFormat formatter = (DecimalFormat) nf; formatter.applyPattern("#,###,###"); String fString = formatter.format(vc); return convertNumbersToEnglish(fString);
