我想从我在Android的Activity中构建一个pdf文件。所以这是代码：
public File creaOrdinePDF(Ordine ordine,String linkImage,Context context){
doc = new Document();
File dir = null;
String path="";
try {
path = Environment.getExternalStorageDirectory()
.getAbsolutePath() + directoryFolder;
dir = new File(path);
if (!dir.exists()) {
dir.mkdirs();
//Toast.makeText(getApplicationContext(), "Directory creata", 10).show();
}
Log.d("PDFCreator", "PDF Path: " + path);
nomeFile="Ordine_negozio_"+ordine.getId();
File file = new File(dir, nomeFile);
FileOutputStream fOut = new FileOutputStream(file);
PdfWriter.getInstance(doc, fOut);
doc.setMargins(5, 5, 30, 30);
doc.open();
Font headerFont = new Font(Font.COURIER, 7.00f, Font.BOLD);
Font tableFont = new Font(Font.COURIER, 8.00f, Font.NORMAL);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
//Bitmap bitmap = BitmapFactory.decodeResource(context
// .getResources(), R.drawable.logo);
Log.d("PDFCreator", "Link immagine " + linkImage);
Bitmap bitmap = BitmapFactory.decodeFile(linkImage);
if(bitmap != null){
Log.d("PDFCreator", "Immagine diversa da null ");
}else{
Log.d("PDFCreator", "Immagine null ");
}
Log.e("PDFCreator","Pippo");
bitmap.compress(Bitmap.CompressFormat.JPEG, 30, stream);
Image myImg = Image.getInstance(stream.toByteArray());
float width = myImg.getWidth();
float height = myImg.getHeight();
float rapp = width / height;
if(width > 260F)
{
myImg.scaleAbsoluteWidth(200F);
myImg.scaleAbsoluteHeight(200F / rapp);
}
if(200F / rapp > 100F)
{
myImg.scaleAbsoluteWidth(rapp * 100F);
myImg.scaleAbsoluteHeight(100F);
}
myImg.setAlignment(Image.MIDDLE);
doc.add(myImg);
Log.e("PDFCreator","aggiunta immagine");
//inserisco il numero dell ordine
Paragraph p2 = new Paragraph("Ordine numero: "+ ordine.getId(),tableFont);
Log.e("PDFCreator","ordine numero "+ordine.getId());
p2.setSpacingAfter(10f);
doc.add(p2);
// add paragraph to document
//doc.add(p1);
float[] dim = {0.7f,3,1.5f,5};
PdfPTable table = new PdfPTable(dim);
table.setWidthPercentage(100);
PdfPCell cell = new PdfPCell(new Paragraph("QTA.", headerFont));
cell.setGrayFill(0.8F);
cell.setUseAscender(true);
cell.setVerticalAlignment(5);
cell.setHorizontalAlignment(0);
cell.setColspan(1);
cell.setBorderWidth(0.5F);
table.addCell(cell);
cell = new PdfPCell(new Paragraph("NOME ARTICOLO", headerFont));
cell.setGrayFill(0.8F);
cell.setUseAscender(true);
cell.setVerticalAlignment(5);
cell.setHorizontalAlignment(0);
cell.setColspan(1);
cell.setBorderWidth(0.5F);
table.addCell(cell);
cell = new PdfPCell(new Paragraph("CODICE ARTICOLO", headerFont));
cell.setGrayFill(0.8F);
cell.setUseAscender(true);
cell.setVerticalAlignment(5);
cell.setHorizontalAlignment(0);
cell.setColspan(1);
cell.setBorderWidth(0.5F);
table.addCell(cell);
cell = new PdfPCell(new Paragraph("NOTE", headerFont));
cell.setGrayFill(0.8F);
cell.setUseAscender(true);
cell.setVerticalAlignment(5);
cell.setHorizontalAlignment(0);
cell.setColspan(1);
cell.setBorderWidth(0.5F);
table.addCell(cell);
Log.e("PDFCreator","size lista articoli "+ordine.getListaArticoli().size());
int i=0;
for(Iterator<ArticoliOrdine> it = ordine.getListaArticoli().iterator(); it.hasNext();)
{
ArticoliOrdine art = it.next();
cell = new PdfPCell(new Paragraph(art.getQuantia()+" pz.", tableFont));
cell.setVerticalAlignment(5);
cell.setHorizontalAlignment(0);
cell.setColspan(1);
cell.setFixedHeight(20);
cell.setBorderWidth(0.5F);
table.addCell(cell);
Log.e("PDFCreator","idArticolo "+ i++);
cell = new PdfPCell(new Paragraph(art.getNomeArticolo(), tableFont));
cell.setVerticalAlignment(5);
cell.setHorizontalAlignment(0);
cell.setColspan(1);
cell.setBorderWidth(0.5F);
table.addCell(cell);
cell = new PdfPCell(new Paragraph(art.getCodiceBarre(), tableFont));
cell.setVerticalAlignment(5);
cell.setHorizontalAlignment(0);
cell.setColspan(1);
cell.setBorderWidth(0.5F);
table.addCell(cell);
cell = new PdfPCell(new Paragraph("", tableFont));
cell.setVerticalAlignment(5);
cell.setHorizontalAlignment(2);
cell.setColspan(1);
cell.setBorderWidth(0.5F);
table.addCell(cell);
}
doc.add(table);
Log.e("PDFCreator", "Fine PDF");
// set footer
Phrase footerText = new Phrase("This is an example of a footer");
HeaderFooter pdfFooter = new HeaderFooter(footerText, true);
doc.setFooter(pdfFooter);
} catch (DocumentException de) {
Log.e("PDFCreator", "DocumentException:" + de);
} catch (IOException e) {
Log.e("PDFCreator", "ioException:" + e);
} catch (Exception e ){
Log.e("PDFCreator", "Exception:" + e);
} finally {
doc.close();
File file = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath() + directoryFolder+"/"+nomeFile);
Log.e("PDFCreator", "return file");
return file;
}
}
但如果我尝试生成它，我就会有这个错误：

答案 0 :(得分：3)
com.lowagie iText（2.1.7或更早版本）在Android上无法使用。你需要 iText v5 （com.itextpdf），更具体地说是Android端口 iTextG ，它排除了Android平台上没有的AWT类：{{3 }}
这就是你得到的原因
Caused by: java.lang.ClassNotFoundException: Didn't find class "java.awt.Color"
有关您的信息，iText（G）v5是AGPLv3，这意味着您的Android应用程序也必须是AGPLv3（即向最终用户发布源代码等），或者您需要购买商业许可证。< / em>的
