寫了個靜態方法使用：

/**
     * Emoji表情校驗
     *
     * @param string
     * @return
     */
    public static boolean isEmoji(String string) {
        //過濾Emoji表情
        Pattern p = Pattern.compile("[^\\u0000-\\uFFFF]");
        //過濾Emoji表情和顏文字
        //Pattern p = Pattern.compile("[\\ud83c\\udc00-\\ud83c\\udfff]|[\\ud83d\\udc00-\\ud83d\\udfff]|[\\u2600-\\u27ff]|[\\ud83e\\udd00-\\ud83e\\uddff]|[\\u2300-\\u23ff]|[\\u2500-\\u25ff]|[\\u2100-\\u21ff]|[\\u0000-\\u00ff]|[\\u2b00-\\u2bff]|[\\u2d06]|[\\u3030]");
        Matcher m = p.matcher(string);
        return m.find();
    }
