5b. Android: formatting numbers based on LOCALE

This example shows you how to format a number based on user's language and region setting (LOCALE)




    /**
     * This method updates the UI with LOCALE specific format
     * e.g. US 1,234.99
     * e.g. Europe 1 234,99
     * @param resultingValue - calculated value to be displayed
     */
   private void updateResult(double resultingValue) {
      NumberFormat nf = NumberFormat.getInstance();
      nf.setMaximumFractionDigits(2);
      nf.setMinimumFractionDigits(0);
      resultingValueTextView.setText(nf.format(resultingValue));
   }
