I opened a document with

PDFOpen(m_doc, this)

next I zoom in with

PDFZoom(..)

now, with OnTouch event I want to "move" inside the document:

....
 switch (event.getAction()) {
                        case MotionEvent.ACTION_DOWN:
                            pp = pdfView.PDFGetPos((int) event.getX(), (int) event.getY());
                            break;
                        case MotionEvent.ACTION_MOVE:
                            pdfView.PDFSetPos(pp, (int) event.getX(), (int) event.getY());
                            break;
      }
.......

I'm able to moving inside the document but if I go to right the reader show me the next page.

Is there a method to block the view only to the current page?
