PrintedPDFDocument 导致 PDF 包含带有网格布局的灰色框
PrintedPDFDocument results in PDF containing Grey box with sort of Grid Layout
经过许多问题,我终于能够使用 PrintedPDFClass 生成具有内容且未损坏的 PDF 文档。
然而,问题是 PDF 中的内容似乎与我给它呈现的视图没有任何关系...
我要渲染的视图:
<?xml version="1.0" encoding="utf-8"?>

这导致 UI 像这样:
我用来生成 PDF 的代码是:
Builder printAttrsBuilder = new Builder();
printAttrsBuilder.setMediaSize(PrintAttributes.MediaSize.ISO_A4);
printAttrsBuilder.setMinMargins(new Margins(5, 5, 5, 5));
PrintedPdfDocument document = new PrintedPdfDocument(context, printAttrsBuilder.build());
PageInfo pageInfo = new PageInfo.Builder(150, 150, 1).create();
Page page = document.startPage(pageInfo);
Canvas pdfCanvas = page.getCanvas();
salesFragmentTableLayout.draw(page.getCanvas());
document.finishPage(page);
File result = null;
FileOutputStream fos = null;
BufferedOutputStream bos= null;
FileDescriptor descriptor = null;
try {
result = File.createTempFile("Kingdom Spas Agreement", ".pdf", context.getCacheDir());
fos = new FileOutputStream(result);
bos = new BufferedOutputStream(fos);
document.writeTo(bos);
descriptor = fos.getFD();
descriptor.sync();
} catch (FileNotFoundException e) {
throw new KingdomSpasException("Failed to find relevent file", e);
} catch (IOException e) {
throw new KingdomSpasException("IO Problem occured while creatin the PDF", e);
} finally {
try {
if (bos != null) { bos.flush(); bos.close(); }
} catch (SyncFailedException e) {
throw new KingdomSpasException("Failed to correctly sync PDF file - may be corrupted", e);
} catch (IOException e) {
throw new KingdomSpasException("Failed to correctly clean up streams", e);
}
}
document.close();
但创建的 PDF 看起来像(以 100% 缩放查看):
任何人都可以向我解释为什么生成的 PDf(至少在我看来)与我的原始视图如此不同并解释如何修复它?

根据 documentation:
public PdfDocument.PageInfo.Builder (int pageWidth, int pageHeight, int pageNumber)
Creates a new builder with the mandatory page info attributes.
Parameters
pageWidth The page width in PostScript (1/72th of an inch).
pageHeight The page height in PostScript (1/72th of an inch).
pageNumber The page number.
您使用一个
PageInfo pageInfo = new PageInfo.Builder(150, 150, 1).create();
Page page = document.startPage(pageInfo);
因此,您创建的页面大小仅为 2 英寸 x 2 英寸。在这个小区域中,只有一部分提交按钮适合。 (PDF 页面内容实际上甚至包含字符串“Submit”,但它远远超出了可视区域。)
当您使用 PrintedPdfDocument
时,您应该改用:
Page page = document.startPage(1);
(cf. the documentation again)
