android字符串转换成16进制怎么转

Answer 1

android字符串转换成16进制，参考如下内容：
/**
* 字符串转换成十六进制字符串
* @param String str 待转换的ASCII字符串
* @return String 每个Byte之间空格分隔，如: [61 6C 6B]
*/
public static String str2HexStr(String str)
{

char[] chars = "0123456789ABCDEF".toCharArray();
StringBuilder sb = new StringBuilder("");
byte[] bs = str.getBytes();
int bit;

for (int i = 0; i < bs.length; i++)
{
bit = (bs[i] & 0x0f0) >> 4;
sb.append(chars[bit]);
bit = bs[i] & 0x0f;
sb.append(chars[bit]);
sb.append(' ');
}
return sb.toString().trim();
}

Answer 2

String转换成16进制的方法：
public static String str2HexStr(String str)

{
char[] chars = "0123456789ABCDEF".toCharArray();
StringBuilder sb = new StringBuilder("");
byte[] bs = str.getBytes();
int bit;
for (int i = 0; i < bs.length; i++) {
bit = (bs[i] & 0x0f0) >> 4;
sb.append(chars[bit]);
bit = bs[i] & 0x0f;
sb.append(chars[bit]);
sb.append(' ');
}
return sb.toString().trim();
}

至于密钥加密得看你用什么加密方式进行加密了
