許多問題後,我終於能夠生成一個PDF文檔,其內容並沒有損壞使用PrintedPDFClass。PrintedPDFDocument導致PDF格式包含灰色框格排列
然而,在PDF內容似乎問題不承擔任何關係,我給它渲染視圖...
,我想呈現的觀點:

導致這樣的UI:
我用它來生成PDF的代碼是:
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();
但創建的PDF樣子(查看100%縮放):
誰能向我解釋爲什麼所產生的PDF(我的眼睛至少)如此不同從我的原始視圖,並解釋如何解決它?

你究竟在哪裏渲染視圖? –
該視圖呈現在最初的活動片段中,並且當用戶單擊該按鈕時,該視圖將被繪製爲pdf。 –
你需要顯示你的整個代碼。 –
