This will have a really simple answer, but I can't seem to find what it is. I want to disable the auto-capitalization of an EditText so that, by default, the first letter entered with not be automatically capitalized. I still want to allow capitalization, but only if the user manually does so.
I've tried android:capitalize="none" on my EditText, and I've tried android:inputType="text" but both still auto-capitalize the first letter. I don't want to use a TextWatcher because on the soft keyboard it will still show the shift key as pressed for the first letter, and I'm nit-picky and don't want that to show.
You could try using android:inputType="none" instead.
UPDATE:
You could also try using android:inputType="text|textEmailAddress"
Have you tried android:inputType="textFilter"? That will disable all text filters, so there's no auto-correcting.
For posterity, I think what you're (or more accurately, whoever finds this in the future) looking for is this table of all the options that can be used for the inputType:

In this specific case, I would recommend "text".Just plain old text. Corresponds to TYPE_CLASS_TEXT | TYPE_TEXT_VARIATION_NORMAL.
