Allowing the User to Enter a Comma-Delimited List of Integers in EditText

Nathan Sokalski 4,126

I have an EditText in which I want to allow the user to enter a list of integers delimited by commas (and/or spaces, or even some other character if that would be easier). However, using things like android:inputType="number" and android:numeric="integer" do not seem to allow the user to enter commas. Is there a good way to allow entry of a (usually short, around 5) list of small integers? I can (and will) obviously manually parse the string, and I can of course use TextChanged to remove invalid characters as they type, but I would like to display the most appropriate & intuitive keyboard for the scenario.

If you do not want to parse the string with TextChanged event, You need to create a custom keyboard for your entry.

I do plan on parsing it, I just want to be able to hide characters like letters but still have the comma available so that the keyboard is more intuitive. A custom keyboard would be nice, but based on everything I have read that either requires extra downloads/installations by the user or can only be done by the phone manufacturer. I don't care if the keyboard displays a few keys like the - & . even though I don't want the user to use those keys, I just want to make it look like a number-related keyboard rather than a letter/text related keyboard. Is there a way to create a custom keyboard that does not require the user to do an extra download?
