Android中byte数组的转换 小灰灰 2022-08-27 03:42 244阅读 0赞 在与服务器的交互过程中,所有的数据都可以看成一段二进制流,那如何把这些二进制流转换成我们需要的数据呢,此文将介绍byte数组转数值的几种方式 1、byte\[\]转换成Long public static long bytesToLong(byte[] bytes,int offset) { long l64; l64=0l; l64 = (long)bytes[offset]&0xff; l64 |= (long)(bytes[offset + 1]&0xff)<<8; l64 |= (long)(bytes[offset + 2]&0xff)<<16; l64 |= (long)(bytes[offset + 3]&0xff)<<24; l64 |= (long)(bytes[offset + 4]&0xff)<<32; l64 |= (long)(bytes[offset + 5]&0xff)<<40; l64 |= (long)(bytes[offset + 6]&0xff)<<48; l64 |= (long)(bytes[offset + 7]&0xff)<<56; return l64; } 2、byte\[\]转换成Int public static int bytesToInt(byte[] bytes,int offset) { int i32; i32=0; i32 = (int)bytes[offset]&0xff; i32 |= (int)(bytes[offset + 1]&0xff)<<8; i32 |= (int)(bytes[offset + 2]&0xff)<<16; i32 |= (int)(bytes[offset + 3]&0xff)<<24; return i32; } 3、byte\[\]转换成Short public static short bytesToShort(byte[] bytes,int offset) { short s16; s16 = (short)(bytes[offset]&0xff); s16 |=(short)(bytes[offset + 1]&0xff)<<8; return s16; }
还没有评论,来说两句吧...
