Using Android:Digits attribute to restrict characters stops action next button working
action, android, digits
Solution
After a bit of poking around with the attributes available for an EditText I found that when I add android:singleLine="true" the ENTER key now moves the focus to the next field, even when a android:digits is restricting the characters entered. Problem solved! (for me, anyway!)
Problem
I have a number of EditText fields on an Android app and I've used android:digits to stop invalid characters being input. eg: `android:digits="@string/validchars"` (where "validchars" is a string resource of all the valid characters - eg A-Z, 0-9, and some punctuation ) The problem is, if the user hits the ENTER key on the soft keyboard it used to take them to the next field but since I added android:digits bit this has stopped working. I've tried adding \n to the `validchars` but this just allows Carriage Returns in the single line textboxes (!) so doesn't help. I've tried fiddling with the imeOptions (adding `actionNext` etc) but this doesn't seem to fix it either. I've read about TextWatchers and InputFilters but both seem to be over-complicated for what I'm trying to do and the `android:digits` bit works fine in stopping the invalid characters. Has anyone got any ideas? I'm using Android SDK version 8 and targeting both 2.2 and 2.3.5 devices.
