我正在使用 epublib 在 WebView 中读取 .epub 文件。
WebView wv = (WebView) getView().findViewById(R.id.chaptercontent);
try {
String abspath = FILEPATH+file;
File filePath = new File(abspath+".epub");
InputStream epubInputStream = new BufferedInputStream(new FileInputStream(filePath));
book = (new EpubReader()).readEpub(epubInputStream);
int pos = abspath.lastIndexOf('/');
DownloadResource(abspath.substring(0, pos));
try {
for(int i = 1; i< book.getContents().size(); i++) {
InputStream is = book.getSpine().getSpineReferences().get(i).getResource().getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
Log.d("display line", line);
}
is.close();
wv.loadDataWithBaseURL(abspath.substring(0, pos)+"/", sb.toString(), "text/html", "utf-8", null);
}
}
catch(IOException e) {
Log.e("IOException", e.getMessage());
}
}
catch (IOException e) {
Log.e("epublib", e.getMessage());
}
private void DownloadResource(String directory) {
try {
nl.siegmann.epublib.domain.Resources rst = book.getResources();
Collection<Resource> clrst = rst.getAll();
Iterator<Resource> itr = clrst.iterator();
Log.d("Downlod path", directory);
while (itr.hasNext()) {
Resource rs = itr.next();
if ((rs.getMediaType() == MediatypeService.JPG) || (rs.getMediaType() == MediatypeService.PNG) || (rs.getMediaType() == MediatypeService.GIF) || rs.getMediaType() == MediatypeService.CSS) {
File oppath1 = new File(directory+File.separator+rs.getHref());
Log.d("Resource Name - ", rs.getHref());
oppath1.createNewFile();
Log.d("Oppath - ", oppath1.getAbsolutePath());
Log.d("File Checking - ", "Exists - "+oppath1.exists()+" & Write - "+oppath1.canWrite());
FileOutputStream fos1 = new FileOutputStream(oppath1);
fos1.write(rs.getData());
fos1.close();
}
}
}
catch (IOException e) {
Log.e("error", e.getMessage());
}
}
DownloadResource 工作正常。资源被获取。但是 WebView 不显示图像。这些图像与 epub 文件位于同一目录中。WebView 给了我这个:
