Hi,
to enable edit text moving you have to edit OnPDFSingleTapped method of PDFReader class as following:
public boolean OnPDFSingleTapped(float x, float y)
	{
		if( m_status == STA_NORMAL || m_status == STA_ANNOT )
		{
			m_annot_pos = m_view.vGetPos((int)x, (int)y);
			m_annot_page = m_view.vGetPage(m_annot_pos.pageno);
			final Page page = m_annot_page.GetPage();
			if( page == null ) m_annot = null;
			else m_annot = page.GetAnnotFromPoint(m_annot_pos.x, m_annot_pos.y);
			if( m_annot == null )
			{
				m_annot_page = null;
				m_annot_pos = null;
				m_annot_rect = null;
				m_view.vSetLock(0);
				if( m_listener != null && m_status == STA_ANNOT )
					m_listener.OnAnnotClicked(m_annot_page, null);
				m_status = STA_NORMAL;
			}
			else
			{
				m_annot_rect = m_annot.GetRect();
				int px = m_annot_page.GetVX(m_view.vGetX());
				int py = m_annot_page.GetVY(m_view.vGetY());
				float tmp = m_annot_rect[1];
				m_annot_rect[0] = m_annot_page.ToDIBX(m_annot_rect[0]) + px;
				m_annot_rect[1] = m_annot_page.ToDIBY(m_annot_rect[3]) + py;
				m_annot_rect[2] = m_annot_page.ToDIBX(m_annot_rect[2]) + px;
				m_annot_rect[3] = m_annot_page.ToDIBY(tmp) + py;
				m_view.vSetLock(3);
				m_status = STA_ANNOT;
				if( m_doc.CanSave() && m_annot.GetEditType() > 3 )	//don't open edit text requetser
				{
					int[] location = new int[2];

                    m_pEdit = new PopupWindow(LayoutInflater.from(getContext()).inflate(R.layout.pop_edit, null) );

Hi Davide,

Could you make this method is compatible with PDFLayoutView, if i use the PDFreader class then my other layouts does not work . I tried to add the text by using PDFReader as its lack of many methods for example (m_view.vGetPage ,m_view.vGetX(), m_view.vGetY() .. etc )

No redo and undo methods in PDFreader so cant use this class . I wanted maximum functionality that is available in only PDFLayoutView class . or in PDFLayoutListener class .

Please provide the methods for these class . I tried to above method with public boolean onSingleTapUp(MotionEvent e) function of PDFLayoutListener but nothing work

please help

Hi Ankuri,
I just managed to do that using the PDFLayoutView class. You need to change the method "public boolean onSingleTapUp(MotionEvent e)" of the PDFGestureListener to make that work.

When single tapping a text annotion this method is displaying an edit text by standard. I changed that so it has the same behaviour when tapping on a stamp: you can move the text annotation around like the stamp.

In the attachment you find my class with the changes. I also modified other functions in that class to suit my needs. So be careful when using it.

Greetings,
Max
