用于验证的请求接口：

https://ccdcapi.alipay.com/validateAndCacheCardInfo.json?_input_charset=utf-8&cardNo=6217002430035835629&cardBinCheck=true

返回：

{"bank":"CCB","validated":true,"cardType":"DC","key":"6217002430035835629","messages":[],"stat":"ok"}

bank 银行的 英文简称

validated 是否通过验证

下面贴个工具类：    使用此工具类可实现链式调用       不要忘记先调用getInstance方法

public class CardUtils {

    public static Map<String,String> bankName = new HashMap<>();

    private CardUtils(){
        bankName.put("ICBC","中国工商银行");
        bankName.put("BOC","中国银行");
        bankName.put("CCB","中国建设银行");
        bankName.put("ABC","中国农业银行");
        bankName.put("HNRCU","河南省农村信用社");
        bankName.put("PSBC","中国邮政储蓄银行");
        bankName.put("CEB","中国光大银行");
        bankName.put("BCM","交通银行");
        bankName.put("CMB","招商银行");
        bankName.put("CMBC","民生银行");
        bankName.put("CDB","国家开发银行");
        bankName.put("CIB","兴业银行");
        bankName.put("BCCB","北京市商业银行");
        bankName.put("HSBC","汇丰银行");
    }

    private static class CardUtilsHolder{
        private static CardUtils holder = new CardUtils() ;
    }

    public static CardUtils getInstance(){
        return CardUtilsHolder.holder;
    }
    
    public static String isBank(String bankStr){
        if (bankName.containsKey(bankStr)){
            Log.e("包含",bankStr);
            return bankName.get(bankStr);
        }
        Log.e("不包含",bankStr);
        return "";
    }
}

使用方法：

String bankName = CardUtils.getInstance().isBank(bankResultBean.getBank());

 可对bankName进行  TextUtils.isEmpty()方法进行判空
