TOPIC:

When a multipage document is rendered on the device , by default the first page is displayed.
I need to customise the code such that any page of the document can be rendered at the first time.

You can achieve this by calling goto method after openning the document:

From where do we need to call this code ,
m_view.PDFGotoPage(index);

We having the following code for opening the document for the first time:

public void PDFOpen(Document doc, boolean rtol, PDFReaderListener listener,
boolean isLoadCurrentPage, int loadCurrentPageNo) {
PDFClose();
m_listener = listener;
m_doc = doc;
m_rtol = rtol;
int back_color = 0xFFCCCCCC;
switch (Global.def_view) {
case 1: {
PDFViewHorz view = new PDFViewHorz(this.getContext());
view.vSetDirection(m_rtol);
m_view = view;
}
break;
case 2:
m_view = new PDFViewCurl(this.getContext());
back_color = 0xFFFFFFFF;
break;
case 3: {
PDFViewDual view = new PDFViewDual(this.getContext());
boolean paras[] = new boolean[m_doc.GetPageCount()];
int cur = 0;
while (cur < paras.length) {
paras[cur] = false;
cur++;
}
view.vSetLayoutPara(null, paras, m_rtol);
m_view = view;
}
break;
case 4:
case 6: {
PDFViewDual view = new PDFViewDual(this.getContext());
view.vSetLayoutPara(null, null, m_rtol);
m_view = view;
}
break;
default:
m_view = new PDFViewVert(this.getContext());
break;
}
m_view.vOpen(m_doc, 4, back_color, this);
m_view.vResize(getWidth(), getHeight());
}

It should be after your method is executed:

Loading a 4 page document and using the PDFReader code of version 3.2
Added the m_view.vGotoPage(3) after the m_view.vOpen(m_doc, 4, back_color, this), its not working.
Its loading the first page and not the third page.

public void PDFOpen(Document doc, boolean rtol, PDFReaderListener listener) {
PDFClose();
m_listener = listener;
m_doc = doc;
m_rtol = rtol;
int back_color = 0xFFCCCCCC;
switch (Global.def_view) {
case 1: {
PDFViewHorz view = new PDFViewHorz(this.getContext());
view.vSetDirection(m_rtol);
m_view = view;
}
break;
case 2:
m_view = new PDFViewCurl(this.getContext());
back_color = 0xFFFFFFFF;
break;
case 3: {
PDFViewDual view = new PDFViewDual(this.getContext());
boolean paras[] = new boolean[m_doc.GetPageCount()];
int cur = 0;
while (cur < paras.length) {
paras[cur] = false;
cur++;
}
view.vSetLayoutPara(null, paras, m_rtol);
m_view = view;
}
break;
case 4:
case 6: {
PDFViewDual view = new PDFViewDual(this.getContext());
view.vSetLayoutPara(null, null, m_rtol);
m_view = view;
}
break;
case 5: {
PDFViewReflow view = new PDFViewReflow(this.getContext());
m_view = view;
}
break;
default: {
PDFViewVert view = new PDFViewVert(this.getContext());
view.vSetPageAlign(1);// center;
m_view = view;
}
break;
}
m_view.vOpen(m_doc, 4, back_color, this);
m_view.vGotoPage(3);
m_view.vResize(getWidth(), getHeight());
}

as said before, after PDFOpen has been executed completely...
