How to set hilight for matched words from search

I tried to use "PDFView.FindStart" and "PDFView.Find" after it finish to render pdf viewer. But it hi-light matched word from wrong page. For example, if I navigate to page 9 and set keyword to "the", it will hil-light "the" in the page 8. Please see the example code below.

Example Code
PDFReader.PDFGotoPage(pageNumber);
txt_find.setText(keyword);
onFindNext();

private void onFindNext()
{
String str = txt_find.getText().toString();
if( str_find != null )
{
if( str != null && str.compareTo(str_find) == 0 )
{
m_reader.PDFFind(1);
return;
}
}
if( str != null && str.length() > 0 )
{
m_reader.PDFFindStart(str, false, false);
m_reader.PDFFind(1);
str_find = str;
}
}

Could you please suggest me how I fix this problem?

That's because the PDFGotoPage takes sometime to do the render, try the following:

I tried by using your code, it does not work. It still search from wrong page. Could you please try to test it by add this code in the file "PDFReaderAct.java"?

Already tested before posting, try to increase the delay (use 100 for example)

Could you provide "PDFReaderAct.java" that you have already modified code to navigate to page and search? I tried to increase delay to 1000 and it does not work.

Here, check PDFReaderAct.InitView()
