Right now I'm using the PDFViewAct activity for show pdf,
How is it possible to define swipe right and left effect to open another pdf file?
for example if the current file is file2.pdf I need swipe left (or right) to open other_file.pdf.
if you have a premium or a professional license you can override the onFling() method of PDFLayoutView class and edit it as you want.
Remember to deallocate all the old instances when you open new PDFs to prevent memory issue.
You can also use a ViewPager with pdfreader inside of it
Look at PDFPagerAct. (this sample project opens only one pdf with a customized ViewPager).
