从android文件中读取二进制数据 [英] Read binary data from file for android

问题描述

我在C＃中使用代码读取二进制数据并转换为字符串

I have working code in C# for read binary data and converted to string

            BinaryReader br = new BinaryReader(File.OpenRead(ofd.FileName));
            string data1 = null;
            for (int i = 0x000001; i <= 0x000002; i++)
            {
                br.BaseStream.Position = i;
                data1 += br.ReadByte().ToString("X2");
            }
if (data1 == "0102") label1.Text = "Trees";

i希望用Java编写代码，但我知道怎么回事



< b>我尝试了什么：



据我所知java使用文件流



有一些java代码，但这个读取整个文件

i want to making that code working in Java, but i donk know how

What I have tried:

as far i know java use filestream

have some java code but this read whole file

FileInputStream fis = new FileInputStream(myExternalFile);
DataInputStream in = new DataInputStream(fis);
BufferedReader br =
        new BufferedReader(new InputStreamReader(in));
String strLine;
while ((strLine = br.readLine()) != null) {
    myData = myData + strLine;
}
in.close();
