打印作业未更新 [英] Printjob not updating

问题描述

我需要在 Android 上更新我的 printJob 方面的帮助.

I need help please with updating my printJob on Android.

我正在修改 printJobInfo，特别是 setCopies 参数，但布局仍将份数读取为 1:

I am modifying the printJobInfo, specifically the setCopies parameter but the layout still reads the number of copies as 1:

PrintManager printManager = (PrintManager) currentActivity.getSystemService(Context.PRINT_SERVICE);

PrintAttributes.Builder attbuilder = new PrintAttributes.Builder();
attbuilder.setMediaSize( PrintAttributes.MediaSize.ISO_A4);

PrintJob newPrintJob = printManager.print(jobName, pda, null);
PrintJobInfo newPrintJobInfo = newPrintJob.getInfo();

PrintJobInfo.Builder jobBuilder = new PrintJobInfo.Builder(newPrintJobInfo);
jobBuilder.setCopies(numberOfCopies);
jobBuilder.setPages(new PageRange[] {PageRange.ALL_PAGES});
jobBuilder.setAttributes(attbuilder.build());

getActivity().getIntent().putExtra(PrintService.EXTRA_PRINT_JOB_INFO, newPrintJobInfo);
getActivity().setIntent(getActivity().getIntent());
getActivity().setResult(Activity.RESULT_OK, result);

但是，这并没有更新我的 printJob，它将属性保持为 null，副本数保持为 1，如 .

However, this is not updating my printJob which keeps the attributes as null and the number of copies as 1 as seen in the .

有什么想法吗???
