[TIMOB-27616] Android: TextField with decimal keyboard type does not allow comma for decimal separator

*Summary:* When using a TextField with "keyboardType" set to KEYBOARD_TYPE_DECIMAL_PAD or KEYBOARD_TYPE_NUMBERS_PUNCTUATION, the end-user is only allowed to enter a period '.' for the decimal point. It ignores the current locale and does not allow other types of decimal separators such as a comma ',' which is used Europe and South America. *How to add languages on Android:*

Go to Android's main Settings screen.

Tap on "System".

Tap on "Language & Input".

Tap on "Languages".

Tap on "Add Language".

Select a European language such as "German"/"Deutsch".

Drag-and-drop the language to the top of the list.

*Steps to reproduce:*

Build and run the below code on Android.

Select a European language. (See language instructions above.)

Tap on the TextField.

Attempt to enter 1,5 with a comma.

Notice it won't let you use a comma ',' for the decimal separator.

Enter 1.5 with a period.

Notice that it allows a period, but this is not correct for the current locale.

var window = Ti.UI.createWindow();
window.add(Ti.UI.createTextField({
	keyboardType: Ti.UI.KEYBOARD_TYPE_DECIMAL_PAD,
	width: "90%",
}));
window.open();

*Note:* This is actually a bug on Google's end. They have a *+partial+* fix for it as of Android 8.0 by using passing the current Locale to a DigitsKeyListener constructor. https://developer.android.com/reference/android/text/method/DigitsKeyListener#DigitsKeyListener(java.util.Locale) Unfortunately, Google's fix is incomplete and has the following issues: * Fullscreen edits (when in landscape) is not fixed. Only allows period for decimal point. * Does not support Arabic decimal separator at all. * Android OS versions older than 8.0 can't use their fix. We need a solution for Android 4.4 too. \\ \\ ---- *Original Post:* In Denmark the decimal separator is comma (,) But when setting

TextField.keyboardType = Ti.UI.KEYBOARD_TYPE_NUMBERS_PUNCTUATION;

Titanium Shows a keyboard with a dot (.) instead... And when parsing a value with Danish Locale 20.50 becomes 2050 On IOS the keyboard is shown with a comma (,) and everything works as expected
