android中打印字节数组,分析字节数组到android或java中的类

我知道关于ByteArrayInputStream的唯一方法是read()，但它只是返回一个整数。分析字节数组到android或java中的类

我有一个类，并在某个地方新建一个变量。那么我将该函数的返回值存储在devCfgBytes中，如何将其读取为int short或byte将其分配给对应的int变量或其他内容。我该怎么办？任何帮助表示赞赏。

public class ScrewCfg {

short u16size;

int u32crc;

boolean bEnable;

byte u8RstFreqDiv;

final static short screwCfgLegth = 438;

//...

}

//new obj in someplace

ScrewCfg devCfg = new ScrewCfg();

//....

btnLoadConfig.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

byte[] devCfgBytes = new byte[ScrewCfg.screwCfgLegth];

int ret = mcLib.ReadUserData(devCfgBytes, ScrewCfg.screwCfgLegth);

if(ret < 0){

showMessage("Load Screw configuration Error!");

return;

}

//any method like this?

//if i want to read it as boolean, then use one byte

//read it as integer, then use the four bytes

ByteArrayInputStream in = new ByteArrayInputStream(devCfgBytes, 1, 1);

DevCfg.bEnable = in.getBoolean();

in = new ByteArrayInputStream(devCfgBytes, 2, 4);

DevCfg.u32crc = in.getInt();

}

});
