Check out
EditText.setFilters(). This allows you to specify one or more instances ofInputFilterfor anEditText. These filter certain characters from the input, as the name suggest. There are a lot of prebuild ones (see “know subclasses” at the top of the class documentation), but you may also implement your own by extending theInputFilterclass.
