View annotations as list in Xamarin.Android

This tutorial only applies to Xamarin.Android. See Xamarin.iOS equivalent here .

The AnnotationDialogFragment displays a list of all annotations in a document being viewed by a PDFViewCtrl. The list also contains any comments that have been added to the annotations.

Annotation dialog

Show annotation dialog

To show an annotation dialog fragment in your activity, create a new instance of AnnotationDialogFragment by calling newInstance() and setting the PDFViewCtrl:

fun showBookmarksDialog(fragmentManager: FragmentManager, pdfViewCtrl: PDFViewCtrl): BookmarksDialogFragment {
    var bookmarksDialog = pdftron.PDF.Dialog.BookmarksDialogFragment.NewInstance();
    List<DialogFragmentTab> tabs = new List<DialogFragmentTab>();
    var annotationsTab = new DialogFragmentTab(
        Java.Lang.Class.FromType(typeof(AnnotationDialogFragment)), BookmarksTabLayout.TagTabAnnotation, null, "Annotations", "Bookmarks Dialog", null);
    bookmarksDialog.SetStyle((int)DialogFragmentStyle.NoTitle, Resource.Style.PDFTronAppTheme);
    bookmarksDialog.Show(fragmentManager, "bookmarks_dialog");
    return bookmarksDialog;


By calling setAnnotationDialogListener(AnnotationDialogListener), you can set a listener to be notified when an annotation item is clicked, or when document annotations are exported to a PDF doc when users click on the export floating action button.


If the document has write access, users can delete existing annotations by long-pressing on the annotation. To specify whether the document is read-only call setReadOnly(boolean).
