about OnPDFBlankTapped

I am testing the search bar. I press the next or previous button for searching. When I pressed those button, sometime will call the OnPDFBlankTapped. But I don't touch any blank place. How can I fix it?
Thank

Hi,
can you reproduce it with the last demo project?
When the OnPDFBlankTapped is called, does the top bar disappear?
If yes, this means that you tapped outside the "next-previous" button area and the behavior is correct.
You can enlarge this area by adding padding or margin to the next-prev buttons in bar_find.xml

Before doing any test clean your project.

Thanks for your replay. I resolved this issue.
I have another question about searching.
I just search some text. I pressed the close button to disable search toolbar and function. But I can see the searching result.
I want to disable searching result after press the close button

Hi,
next time, you should split this question into another post.

To hide results you simply have to call :

I cannot find the PDFFIndEnd function.

Hi,
you will find it in PDFLayoutView
