android – 如何将文件保存到SD卡

InputStream is = new FileInputStream( LOCATIOn + "/zipSample.zip");
ZipInputStream zis = new ZipInputStream(new BufferedInputStream(is));

try {
    ZipEntry ze;
    while ((ze = zis.getNextEntry()) != null) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        byte[] buffer = new byte[1024];

        int count;
        while ((count = zis.read(buffer)) != -1) {
            baos.write(buffer,count);
        }

        String filename = ze.getName();
        byte[] bytes = baos.toByteArray();

        // Do something with 'filename' and 'bytes' ...
        // How do I save to sdcard?
    }
} finally {
    zis.close();
}

非常感谢您的帮助.
