尝试这样的事情，这对我有用

editText.setFilters(new InputFilter[]{new EmojiExcludeFilter()});
private class EmojiExcludeFilter implements InputFilter {

        @Override
        public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
            for (int i = start; i < end; i++) {
                int type = Character.getType(source.charAt(i));
                if (type == Character.SURROGATE || type == Character.OTHER_SYMBOL) {
                    return "";
                }
            }
            return null;
        }
    }
