Rotate document pages in Android

The RotateDialogFragment allows users to rotate pages of the opened document by 90, 180 and 270 degrees. It also displays a thumbnail of the current page at the selected rotation angle.

To show a rotate pages dialog in your activity, create a new instance of RotateDialogFragment by calling newInstance() and setting the PDFViewCtrl:

private PDFViewCtrl mPdfViewCtrl;
// ...
public void showRotateDialog(FragmentManager fragmentManager) {
    RotateDialogFragment.newInstance()
                        .setPdfViewCtrl(mPdfViewCtrl)
                        .show(fragmentManager, "rotate_pages_dialog");
}
