这是我用来将HTML转换为PDF的代码:
public boolean create (String htmlText, String absoluteFilePath) {
try {
Document document = new Document(PageSize.LETTER);
PdfWriter pdfWriter = PdfWriter.getInstance
(document, new FileOutputStream(absoluteFilePath));
document.open();
// Fixing xhtml tag
Tidy tidy = new Tidy(); // obtain a new Tidy instance
tidy.setXHTML(true); // set desired config options using tidy setters
ByteArrayOutputStream output = new ByteArrayOutputStream();
tidy.setCharEncoding(Configuration.UTF8);
tidy.parse(new ByteArrayInputStream(htmlText.getBytes(), output);
String preparedText = output.toString("UTF-8");
Log.i("CHECKING", "JTidy Out: " + preparedText);
InputStream inputStream = new ByteArrayInputStream(preparedText.getBytes());
XMLWorkerHelper.getInstance().parseXHtml(pdfWriter, document,
inputStream, null, Charset.forName("UTF-8"), new MyFont());
document.close();
return true;
} catch (Exception e) {
File file = new File(absoluteFilePath);
if(file.exists()) {
boolean isDeleted = file.delete();
Log.i("CHECKING", "PDF isDeleted: " + isDeleted);
}
LOGGER.error("Exception: " + e.getMessage());
e.printStackTrace();
return false;
}
它适用于以下htmlText
<p dir="ltr"><br>
wwwww<br>
--- <br>

以下 htmlText 不起作用:
<p dir="ltr"><br>
123<br>
--- <br>

请帮我解释为什么它对第二个htmlText的处理与之前不同,并在执行tidy.parse(new ByteArrayInputStream(htmlText.getBytes("ISO-8859-1")), output);
后输出流为空,报错信息为document has no pages
。感谢您的帮助!
