Android与单片机通信常用数据转换方法
1. 将GB2312转化为中文,如BAFAC2DCB2B7→胡萝卜,两个字节合成一个文字
public static String stringToGbk(String string) throws Exception { byte[] bytes = new byte[string.length() / 2]; for (int j = 0; j
2.将中文转化为GB2312,并且结果以byte[]形式返回,如胡萝卜→new byte[]{BA FA C2 DC B2 B7},一个字被分为两个字节
public static byte[] gbkToString(String str) throws Exception { return new String(str.getBytes("GBK"), "gb2312").getBytes("gb2312"); }
3.将十六进制的byte[]原封不动的转化为string,如byte[]{0x7e,0x80,0x11,0x20}→7e801120,可用于log打印
public static String bytesToHexString(byte[] src) { StringBuilder stringBuilder = new StringBuilder(""); if (src == null || src.length <= 0) { return null; } for (int i = 0; i
4.将十六进制的byte[]原封不动的转化为string,并且每个byte之间用空格分开,如byte[]{0x7e,0x80,0x11,0x20}→7e 80 11 20,,可用于log打印
public static StringBuilder byte2HexStr(byte[] data) { if (data != null && data.length > 0) { StringBuilder stringBuilder = new StringBuilder(data.length); for (byte byteChar : data) { stringBuilder.append(String.format("%02X ", byteChar)); } return stringBuilder; } return null; }
5.将byte[]数组转化为8、10、16等各种进制,例如byte[0x11,0x20]→4384,约等于1120(16进制)→4384,radix代表进制
public static String bytesToAllHex(byte[] bytes, int radix) { return new BigInteger(1, bytes).toString(radix);// 这里的1代表正数 }
6.将String的十六进制原封不动转化为byte的十六进制,例如7e20→new byte[]{0x7e,x20}
public static byte[] HexString2Bytes(String src) { byte[] ret = new byte[src.length() / 2]; byte[] tmp = src.getBytes(); for (int i = 0; i
public static byte uniteBytes(byte src0, byte src1) { byte _b0 = Byte.decode("0x" + new String(new byte[] { src0 })) .byteValue(); _b0 = (byte) (_b0 <<4); byte _b1 = Byte.decode("0x" + new String(new byte[] { src1 })) .byteValue(); byte ret = (byte) (_b0 ^ _b1); return ret; }
