java - 如何使用 skyepub 阅读 epub 文件？

Question

我想使用 skyepub SDK 来阅读我的 epub 书籍。但是当我想阅读 epub 时，我总是出现空白屏幕:

03-26 10:46:11.458: I/System.out(1848): GET '/Alexandre Dumas - Les Trois Mousquetaires/META-INF/container.xml'

我在 Application Android 目录中解压了我想阅读的每一本书，所以我猜它与解压无关。

这是代码:http://pastebin.com/BuC9DJsf

解压类:http://pastebin.com/0ervqUy6

这与互联网权限无关，因为我在我的应用程序 list 中放置了必要的权限(包括互联网权限)。

我遇到了同样的问题。但是我解决了!

很简单，你必须解压epub文件。

解压不需要使用AsyncTask。这是我的解压缩代码:

public static String unzip(String path, String zipname) {
    InputStream is;
    ZipInputStream zis;
    String folderName = null;
    try {
        String filename;
        is = new FileInputStream(path + zipname);
        zis = new ZipInputStream(new BufferedInputStream(is));
        ZipEntry ze;
        byte[] buffer = new byte[1024];
        int count;
        boolean firstLoop = true;
        while ((ze = zis.getNextEntry()) != null) {
            // zapis do souboru
            filename = ze.getName();
            if (firstLoop) {
                folderName = filename;
                firstLoop = false;
            }
            // Need to create directories if not exists, or
            // it will generate an Exception...
            if (ze.isDirectory()) {
                File fmd = new File(path + filename);
                fmd.mkdirs();
                continue;
            }

            FileOutputStream fout = new FileOutputStream(path + filename);

            // cteni zipu a zapis
            while ((count = zis.read(buffer)) != -1) {
                fout.write(buffer, 0, count);
            }

            fout.close();
            zis.closeEntry();
        }

        zis.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return folderName;
}

不要忘记在 BookInformation 上设置 SkyProvider。

            SkyProvider skyProvider = new SkyProvider();
            book.isDownloaded = true;
            book.setFileName(fileName);
            book.setBaseDirectory(baseDirectory);
            book.setContentProvider(skyProvider);
            skyProvider.setBook(book.getBook());
            skyProvider.setKeyListener(new KeyDelegate());
            book.makeInformation();
