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:

1BookmarksDialogFragment showBookmarksDialog(FragmentManager fragmentManager, PDFViewCtrl pdfViewCtrl) {
2    DialogFragmentTab annotationsDialog = new DialogFragmentTab(
3        AnnotationDialogFragment.class,
4        BookmarksTabLayout.TAG_TAB_ANNOTATION,
5        null,
6        "Annotations",
7        "Bookmarks Dialog",
8        null);
9    ArrayList<DialogFragmentTab> dialogFragmentTabs = new ArrayList<>();
10    dialogFragmentTabs.add(annotationsDialog);
11
12    BookmarksDialogFragment bookmarksDialog = BookmarksDialogFragment.newInstance();
13    bookmarksDialog.setPdfViewCtrl(pdfViewCtrl)
14        .setDialogFragmentTabs(dialogFragmentTabs);
15    bookmarksDialog.setStyle(DialogFragment.STYLE_NO_TITLE, R.style.PDFTronAppTheme);   
16    bookmarksDialog.show(fragmentManager, "bookmarks_dialog");
17    return bookmarksDialog;
18}

Listener

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.

Read-only

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).
