[android-developers] Re: NumberFormat and comma as decimal separator
Thanks for the comments, I check with my user in Germany and he confirmed that he cannot type the comma into a decimal field in Android. The issue is arising for me because when I copy the text into the edit field I convert it into a localized String which has the comma in it. Once this gets into the edit field it makes my current usage of Double.valueOf fail for the reasons discussed above. I'll probably just change my code to enforce using the period everywhere for consistency until this issue gets fixed in a later version of Android.

[android-developers] Re: NumberFormat and comma as decimal separator
I think that using the Number.valueOf and Number.toString methods
should work fine.
The system should deal with the currently installed and active locale.
Unless you're creating an app that needs to deal with multiple locales
at the same time or do some fancy formatting, i wouldn't bother much
with NumberFormats and such. Just let the java core runtime handle it.

NumberFormat.getInstance() and changed my code as follows:
formatter = NumberFormat.getNumberInstance();
if (formatter instanceof DecimalFormat) {
DecimalFormat format = (DecimalFormat)formatter;
format.applyPattern(PATTERN);
}
I then was going to test it in the emulator and changed my locale to
German. While the language changed there was no change to the number
format and it still used the period as the decimal separator.
Iterating over NumberFormat.getAvailableLocales() I can see that only
English and Japan based countries are returned in the emulator and all
those countries use the period not the comma.
Any ideas on how can I test my changes to make sure they work? I can
override the decimal separator which works fine for testing the
display of numbers, unfortunately the keyboard won't allow me to enter
a comma in a numeric field to test the parsing. My personal Android
phone only supports English and French. I tried changing it to French
but still get the period as the separator, feeling kind of stumped
here.

It's a Android bug.

There is no valueOf method in the Number class. If I use the Double.valueOf method it fails to work according to my users.
