german decimal point in TextField on android

[Nikolaj Weise]

Hi,

in Germany this is a decimal point: ,
and this is a grouping symbol: .

When setting a TextField's constraint to DECIMAL my android phone doesn't let me use comma (,) as decimal point. I cannot write it, means nothing happens when clicking on comma.
It works perfectly on iOS and simulator. They both understand to translate a comma (,) into a real decimal point (.).

What do I have to do to tell android to use german decimal settings?

Hi,
we use the native input for both Android and iOS so this maps to the locale functionality of the native platform.
I suggest checking your Android input settings especially if you installed a custom keyboard.

Google says this is a known issue at the Android SDK. I guess you are using it in some way in your build server.

Is it possible to extend TextField/TextArea or VirtualKeyboard to implement a constraint myself? The easiest (and most dirty) way is to check input with a DataChangeListener. Do you recommend another way?

Hi,

1)We don't use code from the Android SDK for the Text input we simply invoke the platform text input, is this working for you on a simple android native project?

2)You can add DataChangeListener to validate input

From what I've read it works only with a workaround when using android SDK - I did not try.

The nice thing is, when setting a TextField's constraint to DECIMAL the number keyboard shows up automatically when clicking on the TextField. But I can't use a comma then (on android). When using a DataChangeListener I'm able to validate input but I have to use ANY constraint if I want to validate comma. With ANY the qwertz/qwerty keyboard opens instead of the number keyboard. So the user has to change it manually.
How am I able to say that the number keyboard has to show up with using the ANY constraint?

Do you have a link to the suggested workaround?

This approach looks easy: http://stackoverflow.com/a/16772758
(It doesn't check locale but it's a first step to allow comma.)

That should be pretty simple to add. We'll add it conditionally so it doesn't break other code.
In your init(Object) method do:
Display.getInstance().setProperty("andAddComma", "true");

Then if you define a field as decimal the comma character should appear as well (assuming the stack overflow code is correct).
