Answer 1

Actually, iText is intended only for creating PDF, it does not contain part of the viewing. So, you need to choose another library. You can follow the link provided by Ajarahmed to find useful libraries.

Answer 2

You can create your own PDF viewer using iText, you can get images for a specific page and just display this image as a scroll.
But to use this approach, you will need to implement an effective cache and set a threshold for certain pages that will be executed upon initial launch and gradually.
Here is a link to help you:

public void makeImageFromPDF throws DocumentException, IOException { String INPUTFILE = Environment.getExternalStorageDirectory() .getAbsolutePath()+"/YOUR_DIRECTORY/inputFile.pdf"; String OUTPUTFILE = Environment.getExternalStorageDirectory() .getAbsolutePath()+"/YOUR_DIRECTORY/outputFile.pdf"; Document document = new Document(); PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(OUTPUTFILE)); document.open(); PdfReader reader = new PdfReader(INPUTFILE); int n = reader.getNumberOfPages(); PdfImportedPage page; // Traversing through all the pages for (int i = 1; i <= n; i++) { page = writer.getImportedPage(reader, i); Image instance = Image.getInstance(page); //Save a specific page threshold for displaying in a scroll view inside your App } document.close(); }
