Decimal point or decimal comma in Android

Question

Is there an easy way to read back if the language set uses a decimal comma or a decimal point?

Answer 1

EDIT: Updating based on @Algar's suggestion; you can directly use:

char separatorChar = DecimalFormatSymbols.getInstance().getDecimalSeparator(); 

As it will always return an instance of DecimalFormatSymbols.

NumberFormat nf = NumberFormat.getInstance(); if (nf instanceof DecimalFormat) {     DecimalFormatSymbols sym = ((DecimalFormat) nf).getDecimalFormatSymbols();     char decSeparator = sym.getDecimalSeparator(); } 

Docs:

NumberFormat, DecimalFormat, DecimalFormatSymbols

According to the DecimalFormat docs, apparently calling NumberFormat.getInstance() is safe, but may return a subclass other than DecimalFormat (the other option I see is ChoiceFormat). I believe for the majority of instances it should be a DecimalFormat, and then you can compare decSeparator against a , and . to see which format it is using.
