函数boolean containsAny(String str, String searchChars) 判断str字符串中是否包含searchChars字符串

String khh_str = "";        if(list.size()>0){            khh_str = "('";            for (int i = 0; i < list.size(); i++) {                String now_khh = list.get(i).getKhh().trim();                if(!khh_str.contains(now_khh)){                    if(i>0){                        khh_str += "','";                    }                    khh_str += now_khh;                }            }            khh_str += "')";        }
