如何创建多个图像文件的zip文件 [英] How to create a zip file of multiple image files

问题描述

我正在尝试创建多个图像文件的zip文件。我已成功创建所有图像的zip文件，但不知何故所有图像都被挂起到950字节。我不知道这里出了什么问题，现在我无法打开将图像压缩成该zip文件。

I am trying to create a zip file of multiple image files. I have succeeded in creating the zip file of all the images but somehow all the images have been hanged to 950 bytes. I don't know whats going wrong here and now I can't open the images were compressed into that zip file.

这是我的代码。谁能让我知道这里发生了什么？

Here is my code. Can anyone let me know what's going here?

String path="c:\\windows\\twain32";
File f=new File(path);
f.mkdir();
File x=new File("e:\\test");
x.mkdir();
byte []b;
String zipFile="e:\\test\\test.zip";
FileOutputStream fout=new FileOutputStream(zipFile);
ZipOutputStream zout=new ZipOutputStream(new BufferedOutputStream(fout));


File []s=f.listFiles();
for(int i=0;i<s.length;i++)
{
    b=new byte[(int)s[i].length()];
    FileInputStream fin=new FileInputStream(s[i]);
    zout.putNextEntry(new ZipEntry(s[i].getName()));
    int length;
    while((length=fin.read())>0)
    {
        zout.write(b,0,length);
    }
    zout.closeEntry();
    fin.close();
}
zout.close();

推荐答案

更改此信息：

while((length=fin.read())>0)

到此：

while((length=fin.read(b, 0, 1024))>0)

并将缓冲区大小设置为1024字节：

And set buffer size to 1024 bytes:

b=new byte[1024];
