Answer 1

First need to add DigitsKeyListener for allowing characters and then setRawInputType to edittext field

edit_field.setKeyListener(DigitsKeyListener.getInstance("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"));


edit_field.setRawInputType(InputType.TYPE_TEXT_VARIATION_PERSON_NAME);
