Question

我正在做一个Android项目。我需要压缩SD卡的完整文件夹结构。如果文件夹中存在任何文件，代码可以压缩文件夹，否则跳过该文件夹。

我的文件夹结构如：mnt / sdcard / Movies / Telugu / Files。

mnt / sdcard / Movies / English - ＆gt;英文是空文件夹

我没有在输出zip文件中看到英文文件夹。

我的代码：

public void zip() {
    try {
        // create a ZipOutputStream to zip the data to
        ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(
                _zipFile));

        zipDir(folderPath, zos);
        // close the stream
        zos.close();
    } catch (Exception e) {
        // handle exception
    }

}

public void zipDir(String dir2zip, ZipOutputStream zos) {
    try {
        File zipDir = new File(dir2zip);
        // get a listing of the directory content
        String[] dirList = zipDir.list();
        byte[] readBuffer = new byte[2156];
        int bytesIn = 0;
        // loop through dirList, and zip the files
        for (int i = 0; i < dirList.length; i++) {
            File f = new File(zipDir, dirList[i]);
            if (f.isDirectory()) {
                // if the File object is a directory, call this
                // function again to add its content recursively
                String filePath = f.getPath();
                zipDir(filePath, zos);
                // loop again
                continue;
            }
            // if we reached here, the File object f was not a directory

            // create a FileInputStream on top of f
            FileInputStream fis = new FileInputStream(f);
            // create a new zip entry
            ZipEntry anEntry = new ZipEntry(f.getPath());
            // place the zip entry in the ZipOutputStream object
            zos.putNextEntry(anEntry);
            // now write the content of the file to the ZipOutputStream
            while ((bytesIn = fis.read(readBuffer)) != -1) {
                zos.write(readBuffer, 0, bytesIn);
            }
            // close the Stream
            fis.close();
        }
    } catch (Exception e) {
        e.printStackTrace();
        // handle exception
    }
}

请帮助..

您基本上不会为您的目录创建zipentry。

在if (f.isDirectory()) {}部分，添加以下内容：

zos.putNextEntry(new ZipEntry(filePath));

您也可以将其放在方法的开头，也可以包含根目录。

空文件夹不添加到zip文件android
