Change DecimalFormat locale

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.

Solution

  • 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);
