Question

我找到了一个使用epublib在android中阅读epub书籍的解决方案。我能够阅读这本书的字幕。但我没有找到一种方法来逐行阅读内容。我怎么能实现这个目标呢？

获取图书标题的示例代码是

  private void logTableOfContents(List<TOCReference> tocReferences, int depth) {
    if (tocReferences == null) {
        return;
    }
    for (TOCReference tocReference : tocReferences) {
        StringBuilder tocString = new StringBuilder();
        StringBuilder tocHref=new StringBuilder();
        for (int i = 0; i < depth; i++) {
            tocString.append("\t");
            tocHref.append("\t");
        }
        tocString.append(tocReference.getTitle());

        tocHref.append(tocReference.getCompleteHref());
        Log.e("Sub Titles", tocString.toString());
        Log.e("Complete href",tocHref.toString());

        //logTableOfContents(tocReference.getChildren(), depth + 1);
    }
}

我怎样才能得到这本书的故事......

Answer 1

我不确定这是在epub文件中导航的方法。据我所知（直到现在 - 我还在学习），更好的方法来获得所有书籍cocntent是基于脊柱部分。但仍然 - 我不知道如何将这两件事（TOC和真正的脊椎）与epublib接口连接起来。根据文件： “脊柱部分是本书的各个部分，按照阅读本书的顺序。这与目录部分形成对比，这是本书部分的索引。”

这是某种东西 - 如果你喜欢 - 这是一个片段：

Spine spine = new Spine(book.getTableOfContents());
for (SpineReference bookSection : spine.getSpineReferences()) {
            Resource res = bookSection.getResource();
                try {
                    InputStream is = res.getInputStream();
                    //do something with stream
                } catch (IOException e) {

嗯 - 我不确定导航，但也想知道如何做到这一点现在 - 我有类似的东西（逐行阅读）：

private void logTableOfContents(List<TOCReference> tocReferences, int depth) {
    if (tocReferences == null) {
        return;
    }
    for (TOCReference tocReference : tocReferences) {
        StringBuilder tocString = new StringBuilder();
        for (int i = 0; i < depth; i++) {
            tocString.append("\t");
        }
        try{
           InputStream is = tocReference.getResource().getInputStream();
           BufferedReader r = new BufferedReader(new InputStreamReader(is));
           String line;
           while ((line = r.readLine()) != null) {
               String line = Html.fromHtml(line).toString();
           }
        }
        catch(IOException e){

        }




        //logTableOfContents(tocReference.getChildren(), depth + 1);
    }
}

我尝试使用此代码逐行读取epub文件中的所有文本，但它不能正常工作！我怎样才能做到这一点？

    BufferedReader r = new BufferedReader(new  InputStreamReader(is));
