Use custom input filter and then set it to the editText.

InputFilter filter = new InputFilter() {
    public CharSequence filter(CharSequence source, int start, int end,
            Spanned dest, int dstart, int dend) {
        char[] chars = {'\'','"'};
        for (int i = start; i < end; i++) {
            if (new String(chars).contains(String.valueOf(source.charAt(index))) {
                return "";
            }
        }
        return null;
    }
};
edit.setFilters(new InputFilter[] { filter });
