注意：开发人员需要从[iTextPdf]（http://itextpdf.com/terms-of-use/）购买商业许可证，以便在非开放源代码应用程序中使用iTextPdf库。 –

@OctavianDamiean好的，但是当我有答案时该怎么办，但是没有很好的解释..你可以请写给我看，因为*你没有答案* [你肯定会发布我确定]是的，但是作为看到你的经验，你必须得到相同的解释我相信...所以请帮我编辑答案， –

@RadheMohan什么是subCatPart？你能添加一些细节吗？ – RobinHood

下面是代码：（日志报表解释）

String path = null ; 

File file=new File("/mnt/sdcard/PDFfiles"); 

File f = new File(file, "MyPDFFILE.pdf"); 

Log.v("stage 1","store the pdf in sd card"); 

Document document = new Document(PageSize.A4, 38, 38, 50, 38); 

Log.v("stage 2","Document Created"); 

PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(path)); 

Log.v("Stage 3", "Pdf writer"); 

document.open(); 

Log.v("Stage 4", "Document opened"); 

document.add(new Paragraph("First Paragraph")); 

Log.v("Stage 5", "Creating Paragraph"); 

Image image = Image.getInstance ("/mnt/sdcard/images/3_5_9_0001.jpg"); 

Log.v("Stage 6", "Image path adding"); 

image.setAlignment(Image.MIDDLE| Image.TEXTWRAP); 

Log.v("Stage 7", "Image Alignments"); 

image.setBorder(Image.BOX); 

image.setBorderWidth(15); 

document.add(image); 

Log.v("Stage 8", "Image adding"); 

document.close(); 

Log.v("Stage 7", "Document Closed");
