Just change onSizeChanged from PDFReader to below code. This will scale vertical PDF to fit screen height. If PDF height is high than screen size try to change
m_view.vSetScale((m_view.vGetMaxScale() / 2), 0, 0);
according to your need.
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
if (m_view == null)
return;
PDFPos pos = m_view.vGetPos(w / 2, h / 2);
m_view.vResize(w, h);
float max_w = m_doc.GetPageWidth(0);
float max_h = m_doc.GetPageHeight(0);
int page = 1;
int pages_cnt = m_doc.GetPageCount();
while (page < pages_cnt) {
float doc_w = m_doc.GetPageWidth(page);
float doc_h = m_doc.GetPageHeight(page);
if (max_w < doc_w)
max_w = doc_w;
if (max_h < doc_h)
max_h = doc_h;
page++;
}
if ((max_w > max_h || ((Activity) context).getResources()
.getConfiguration().orientation == ((Activity) context)
.getResources().getConfiguration().ORIENTATION_LANDSCAPE)
&& (max_w > w || ((Activity) context).getResources()
.getConfiguration().orientation == ((Activity) context)
.getResources().getConfiguration().ORIENTATION_LANDSCAPE))
m_view.vSetScale(0, 0, 0);
else
m_view.vSetScale((m_view.vGetMaxScale() / 2), 0, 0);// fit page
// while
// resizing.
// m_view.vSetScale(0, 0, 0);// fit page while resizing.
if (m_goto_pageno >= 0) {
m_view.vGotoPage(m_goto_pageno);
m_goto_pageno = -1;
} else if (pos != null) {
m_view.vSetPos(pos, w / 2, h / 2);
