无法从Android上创建的ZIP存档中提取文件(特定于设备 *** 作系统)

概述我正在使用以下代码在 Android上创建存档： OutputStream os = new FileOutputStream(zipFile); ZipOutputStream zos = new ZipOutputStream(new BufferedOutputStream(os)); try { zos.setLevel(8); b 我正在使用以下代码在 Android上创建存档：

OutputStream os = new fileOutputStream(zipfile);    ZipOutputStream zos = new ZipOutputStream(new bufferedoutputstream(os));    try     {        zos.setLevel(8);        byte[] buffer = new byte[32768];        for (Vfile src : topack)                    {            ZipEntry entry = new ZipEntry(src.name);            zos.putNextEntry(entry);            src.pushToStream(zos,buffer);            src.close();            zos.closeEntry();        }    }    finally     {        zos.close();    }

我发现只有一种压缩方法可用 – DEFLATED(只有STORED替代品可用).这意味着始终使用一种方法压缩存档.

如果我在AndroID 2.3.4上运行此代码 – 我可以使用7Zip解压缩windows中的文件;如果我在AndroID 3上运行它(或三星galaxy Tab;不确定谁错了) – 7Zip显示存档列表,但无法解压缩文件说不支持的压缩方法.同时7Zip将Deflate显示为文件上的压缩方法,这意味着它可以正确处理它.

有人有这个问题吗？

谢谢.

UDP：发现另一个topic with similar issue(虽然可能不一样).

解决方法 @ user1269737的答案是正确的;几乎.但它仅适用于单文件存档.
下面是一个解析整个存档的代码.
