Printing a double value with 2 decimals with a . not a ,

Question

I have a little problem in an app I am working on. I am using some double values and I want to place them in some TextViews, but when the number is placed, instead of "." it appears ",". I would like to have a dot so I can import the value with a substring.

DecimalFormat precision = new DecimalFormat("0.00");
final TextView totalPrice = (TextView) getView().findViewById(R.id.actualPrice);
double price = 200.12357123;
totalPrice.setText("$" + precision.format(price));

Inside the TextView will appear 200,12 and I would like to appear 200.12, so I can convert the text in a double value later on.

But your code is working in my project just removing getView(). — Dileep Patel, Jan 23 '18 at 12:29
@DileepPatel The result what `DecimalFormat` creates depends on the user-specific `Locale`. — , Jan 23 '18 at 12:44
Set the `Locale` to one with [dot as decimal separator](https://docs.oracle.com/cd/E19455-01/806-0169/overview-9/index.html) — artkoenig, Jan 23 '18 at 13:25

Try this

Locale currentLocale = Locale.getDefault();
String formatString = "#,###,###,###.##";
DecimalFormatSymbols otherSymbols = new DecimalFormatSymbols(currentLocale);
otherSymbols.setDecimalSeparator(',');
otherSymbols.setGroupingSeparator('.');
DecimalFormat df = new DecimalFormat(formatString, otherSymbols);

double price = 200.12357123;

Log.i("TAG", "" + "$ " + df.format(price));

OUTPUT

Use below code it will give an exactly same answer as you want:

double price = 200.12357123;
String s=String.format(Locale.US, "$%.2f", price);

You can change the '.' with ',' ,when you want to convert to double.
