將HTML轉換成PDF android系統

我想一個html文件轉換爲PDF 我的代碼是將HTML轉換成PDF android系統

Document document = new Document(); 
boolean mExternalStorageAvailable = false; 
boolean mExternalStorageWriteable = false; 
String state = Environment.getExternalStorageState(); 
if (Environment.MEDIA_MOUNTED.equals(state)) { 
    mExternalStorageAvailable = mExternalStorageWriteable = true; 
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) { 
    mExternalStorageAvailable = true; 
    mExternalStorageWriteable = false; 
} else { 
    mExternalStorageAvailable = mExternalStorageWriteable = false; 
} 
String file = null; 
if (mExternalStorageWriteable) { 
    file = Environment.getExternalStorageDirectory() + "/abcd.pdf"; 
} 

document.open(); 
PdfCopy writer = new PdfCopy(document, new FileOutputStream(file)); 

InputStream is = new FileInputStream(Environment.getExternalStorageDirectory()+"/new1.html"); 

PdfReader reader = new PdfReader(is); 

PdfImportedPage page; 
int n = reader.getNumberOfPages(); 
page = writer.getImportedPage(reader, n); 
Image instance = Image.getInstance(page); 
document.add(instance); 

document.close(); 
Toast.makeText(this, "pdf created", Toast.LENGTH_LONG).show();

我已經使用itextpdf-5.4.3.jar。同時運行此代碼我得到一個異常「找不到PDF頭標識」 ......任何一個可以幫助我

的錯誤是因爲你試圖讀取HTML文件使用PdfReader PDF文檔。

您可以參閱「iText in Action」一書中的HtmlMovies1示例，該示例使用已棄用的HTMLWorker進行HTML到PDF的轉換，或查看新的XML Worker項目的API文檔。

This class獨立於iText工作。不過來編譯，它必須在包裝「.../JAVA /安卓/打印/」

下面是一個簡單的代碼示例：

PdfConverter converter = PdfConverter.getInstance(); 
File file = new File(Environment.getExternalStorageDirectory().toString(), "file.pdf"); 
String htmlString = "<html><body><p>WHITE (default)</p></body></html>"; 
converter.convert(getContext(), htmlString, file); 
// By now the pdf has been printed in the file.
