有项目使用到了TLV组解包的模式，特意在此记录，以供参考：

/**

* Created by ZFR on 2019/5/29.

*/

public class TlvUtils {

/**

*

* @param hexString

* @return

*/

public static ListbuilderTlvList(String hexString) {

Listtlvs = new ArrayList();

int position = 0;

while (position != StringUtils.length(hexString)) {

String _hexTag = getTag(hexString, position);

Log.d("zfr-_hexTag:===", _hexTag);

position += _hexTag.length();

LPositon l_position = getLengthAndPosition(hexString, position);

int _vl = l_position.get_vL();

position = l_position.get_position();

String _value = StringUtils.substring(hexString, position, position + _vl * 2);

position = position + _value.length();

tlvs.add(new TLV2(_hexTag, _vl, _value));

}

return tlvs;

}

/**

*/

public static MapbuilderTlvMap(String hexString) {

Maptlvs = new HashMap();

String _hexTag = getTag(hexString, position);

position += _hexTag.length();

LPositon l_position = getLengthAndPosition(hexString, position);

int _vl = l_position.get_vL();

position = l_position.get_position();

String _value = hexString.substring(position, position + _vl * 2);

position = position + _value.length();

tlvs.put(_hexTag, new TLV2(_hexTag, _vl, _value));

}

return tlvs;

}

/**
