我正在尝试为 android 创建一个 epub 阅读器，所以经过大量搜索后我找到了 skyepub library (SDK)。似乎它具有我想要的所有功能。
我按照站点中的提示进行操作，但是在运行代码后我得到了一个空白屏幕 和针对不同 api 的不同 logcat，我再次检查了代码并 agian 但我找不到是什么错了。
这是我的代码和 logcat，我们将不胜感激。

最佳答案
您只需要将您的 epub 图书解压缩到您的基本目录(在您的例子中是/book/filename)。 您必须将 books 文件夹中的 epub 文件解压为 epub 文件名。
您可以在下面的链接中看到完整的演示
http://www.skytree21.com/cgi-bin/download.php?os=android&version=3.9.8&type=core_sample
在 Demo 中，在 LocalService 类中，您将获得解压缩文件的代码。 在这个演示中，他们从网上下载了 epub 文件，下载后首先将其移动到手机目录中的下载文件夹，然后将其解压缩到手机目录中的基本目录 books，然后 skyepub SDK 将通过设置 setBaseDirectory 直接获取其路径。
这是将 Assets 文件移动到下载文件夹到手机目录后解压缩文件的代码
public void unzipBook(String fileName) {
String targetDir = new String(getFilesDir().getAbsolutePath() + "/books/" + fileName);
targetDir = SkyUtility.removeExtention(targetDir);
String filePath = new String(getFilesDir().getAbsolutePath() + "/downloads");
Unzip unzip = new Unzip(fileName, filePath, targetDir);
unzip.addObserver(new UnzipHandler());
unzip.unzip();
}
class UnzipHandler implements Observer {
@Override
public void update(Observable observable, Object data) {
//Unzip completed
(new Handler()).postDelayed(new Runnable() {
public void run() {
}
},500);
}
}
在您的情况下，您只需获取您的 Assets 引用并解压缩它。您会成功的。

有没有人有一个很好的Ruby脚本来使用他们的API在Amazon上查找书籍(或其他产品)？ 最佳答案 我一直在使用Amazon/ECS取得了巨大的成功。重要的一点是它不是GPL的(而Ruby/AWS似乎是)，所以如果它对您的情况很重要，请小心。这是一个示例:require'amazon/ecs'#defaultoptions;willbecamelizedandconverted#toRESTrequestparameters.Amazon::Ecs.options={:aWS_access_key_id=>[youraccessk
我只是想通过向DOM添加脚本标记来加载GWT(GoogleWebToolkit)应用程序，但是因为GWT链接器使用document.write()我无法找到任何这样做的好方法。我在各种博客文章中发现了一些这样做的技巧，但它们似乎都无法使用最新版本的GWT。想到任何合理的非侵入性方法来执行此操作吗？澄清:在您的主机html页面中启动GWT应用程序的正常方法:当然，这会在页面加载后立即启动。我想稍后再做:functionstartapp(){varhead=document.getElementsByTagName('head');vars=document.createElement('

我想知道是否可以做类似this的事情使用Javascript。我认为这是一件很难实现的事情(只需尝试调整窗口大小)，而且我不知道网络上是否有一些东西(虽然我没有找到任何东西)。 最佳答案 如果您能够将整本书的文本传递到页面，这很简单。简单待办事项列表(MVC)PHP:从db获取书籍并将其内容传递给view创建四个DIV首先到上一页操作左页第二个右页第三页第四到下一页Action这些DIV是浏览器窗口的100%高度，它们的宽度是:30px(page.width-60)/2(page.width-60)/230px并且通过Javascr
本课设系软件工程大二学生作，拙笔狂言，恭请斧正。开发工具：Eclipse2020-12，MicrosoftSQLserver2012程序语言：Java引言选题题目：图书管理系统选题背景：（1）图书室有各种图书，共一万多册。（2）每种图书都有书名、书号（ISBN）、一名或多名作者（译者）、出版社、定价和内容简介。（3）借书证记录有借阅者的姓名、所在单位、职业等。（4）凭借书证借书，每次最多能借8本书。借书期限最长为30天。需求功能：（1）图书基本情况的录入、修改、删除等基本操作。（2）实现借书功能。（3）实现还书功能。（4）实现对所有购进图书的分类查询和分类统计。（5）能够按书名、作者等分类查询
我有一个正在开发的JavaScript库。我已将它构建成许多文件，并使用模块方法来定义每个“模块”。varns=generateNamespace("me.mycompany.mypackage.MyFile");(function(ns,undefined){//somemodule}(ns));模块是使用命名空间函数动态命名的，这意味着就目前情况而言，自动完成几乎是不可能的(除非Eclipse可以运行我的代码并找出命名空间，否则VisualStudio可以!)。因此我打算为我的项目生成JSdoc，希望如果我将它包含到Eclipse中(以某种方式)Eclipse可以使用它来为我提供内
我想使用mocha(node.js测试框架，而不是ruby模拟库)作为库，而不是使用mocha可执行文件来运行我的测试。是否可以通过这种方式运行mocha测试？这些示例都只是调用mocha库，假设它们已经“需要”，并且mocha可执行文件提前完成所有“需要”，但我真的更愿意在我的脚本中明确地执行它们，这样我就可以简单地在我的脚本上设置+x并直接调用它。我可以做这样的事情吗？#!/usr/bin/envcoffeemocha=require'mocha'test=mocha.Testsuite=mocha.Suiteassert=require("chai").assertthing
我想将添加的作者与可以由jQuery添加的其他作者分开。当我添加一位作者时，我希望能够将该作者链接到他的书，例如，在我按下添加作者按钮后，我得到了另一位作者的表格，但在我的代码中，所有作者都在一个数组中，所有的书都在其他。不与作者及其书籍分离。我想通过邮寄方式发送:author1:{book1,book2,book3}author2:{book4,book5}author3:{book6,book7,book8,book9}这是我目前的代码:AddAuthorAddAuthorBooks$(document).ready(function(){varmax_fields=10;//ma

我需要安装KOHAILS在Windows7中，但事实证明它只能安装在Ubuntu上。谁能给我一些关于如何在Windows7上安装它的指南？非常感谢任何帮助。 最佳答案 Koha可以在任何基于Linux的系统上运行。在Debian或Ubuntu上安装和使用最简单，因为可用的软件包非常容易安装-手动安装可能既困难又耗时。Ubuntu指令在这里:http://wiki.koha-community.org/wiki/Koha_on_ubuntu_-_packages您可以使用VirtualBox软件(virtualbox.org)在Win
