我在使用Base64编码png图像然后与HTML字符串连接时遇到问题。
当我将编码的图像打印到AS的日志中时，我会完美地获得所有字符串，但是如果我像下面这样连接（htmlToPDF变量），则我在Log中看不到所有字符串。似乎是截断的。我不知道发生了什么。
public void gerarPDFOnClick()
{
Document document = new Document(PageSize.LETTER);
String NOME_ARQUIVO = "MeuArquivoPDF.pdf";
String pastaArmazenamento = Environment.getExternalStorageDirectory().toString();
File pdfDir = new File(pastaArmazenamento + File.separator + NOME_PASTA);
if(!pdfDir.exists())
{
pdfDir.mkdir();
}
File pdfSubDir = new File(pdfDir.getPath() + File.separator + GERADOS);
if(!pdfSubDir.exists())
{
pdfSubDir.mkdir();
}
String nomeCompleto = Environment.getExternalStorageDirectory() + File.separator + NOME_PASTA + File.separator + GERADOS
+ File.separator + NOME_ARQUIVO;
File outputFile = new File(nomeCompleto);
if(outputFile.exists())
{
outputFile.delete();
}
try {
PdfWriter pdfWriter = PdfWriter.getInstance(document, new FileOutputStream(nomeCompleto));
/*Criar o ducumento para escreve-lo */
document.open();
document.addAuthor("Felipe Cardim");
document.addCreator("Criador");
document.addSubject("Obrigado por ajudar");
document.addCreationDate();
document.addTitle("Titulo uhuuuuu");
XMLWorkerHelper workerHelper = XMLWorkerHelper.getInstance();
bitmap.compress(Bitmap.CompressFormat.PNG,100,baos);
byte[] b = baos.toByteArray();
String encodeImage = Base64.encodeToString(b,Base64.DEFAULT);
String htmlToPDF = "<html>" +
"<head></head>" +
"<body>" +
"<h1>Aeeeeee</h1>" +
"<a href='https://www.facebook.com/profile.php?id=736342513'>Facebook</a>" +
"<p>huhuhuhuhuhuh</p>" +
"<img src=\"data:image/png;base64," + encodeImage + "\"" +
" height='42' width='42'/>" +
"</body>" +
"</html>";
Log.i("encode",encodeImage);
Log.i("HTMLTOPDF",htmlToPDF);
try {
workerHelper.parseXHtml(pdfWriter,document, new StringReader(htmlToPDF));
document.close();
Toast.makeText(this, "PDF esta criado!!",Toast.LENGTH_LONG).show();
mostraPDF(nomeCompleto, this);
} catch (IOException e) {
e.printStackTrace();
}
}catch (DocumentException e){
