推荐答案

这是一些基本的拉链code。从本质上创建一个字符串数组，其中包含所有你想要在zip和另一个字符串为您的zip文件的目标路径，包括映像文件的路径。关于该方法通过这些

This is some basic zip code. Essentially create a string array containing all the image file paths you want to include in the zip and another string for the destination path of your zip file. Pass these on to the method.

public static void zip(String[] files, String zipFile) throws IOException {
BufferedInputStream origin = null;
ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(new FileOutputStream(zipFile)));
try { 
    byte data[] = new byte[BUFFER_SIZE];

    for (int i = 0; i < files.length; i++) {
        FileInputStream fi = new FileInputStream(files[i]);    
        origin = new BufferedInputStream(fi, BUFFER_SIZE);
        try {
            ZipEntry entry = new ZipEntry(files[i].substring(files[i].lastIndexOf("/") + 1));
            out.putNextEntry(entry);
            int count;
            while ((count = origin.read(data, 0, BUFFER_SIZE)) != -1) {
                out.write(data, 0, count);
            }
        }
        finally {
            origin.close();
        }
    }
}
finally {
    out.close();
}

}

或者，您可以使用 Zip4j 库。

编程快乐！ ：D
