我正在使用PDFDocument类将RelativeLayout在运行时填充的内容转换为 PDF。我知道如何为 1 页 PDF 执行此操作，但是，如果在运行时，RelativeLayout没有页面 > 1，那么我不知道如何执行此操作。我想我必须拆分文本 - 但我不知道该怎么做。

这是XML

这是 createPDF() 的片段 

private void creatPDF() {
PdfDocument mypdfdoc = new PdfDocument();
PdfDocument.PageInfo mypageinfo1 = new PdfDocument.PageInfo.
Builder(1200, 2010, 1).create();

//page 1
PdfDocument.Page mypage1 = mypdfdoc.startPage(mypageinfo1);

//measurements for page 1
int measureWidth = View.MeasureSpec.makeMeasureSpec(mypage1.getCanvas().getWidth(), View.MeasureSpec.EXACTLY);
int measuredHeight = View.MeasureSpec.makeMeasureSpec(mypage1.getCanvas().getHeight(), View.MeasureSpec.EXACTLY);

//put content on page 1
View contentQ1 = findViewById(R.id.allQuizzesSV);
contentQ1.measure(measureWidth, measuredHeight);
contentQ1.layout(0, 0, measureWidth, measuredHeight);
contentQ1.draw(mypage1.getCanvas());

//finish page 1
mypdfdoc.finishPage(mypage1);

String path1 = this.getExternalFilesDir(null).getAbsolutePath();
File mFile = new File(path1,"QuizSummaryN.pdf");

try{
mypdfdoc.writeTo(new FileOutputStream(mFile));
}catch (IOException e){
e.printStackTrace();
Toast.makeText(this, "Something wrong: " + e.toString(), Toast.LENGTH_LONG).show();
}
mypdfdoc.close();
}

这是 PDF 格式的示例输出 在此处输入图像描述

在图片中，我也描述了我的问题。

你能指出我正确的方向吗？非常感谢
