I am facing difficulties to adjust an application page layout in android studio, generate image and save in pdf. I have a layout with several Textview and a Listview with scrolling, I can transform the layout into bitmap and save to pdf, but as the listview has many items, the image comes out only with what is appearing on the screen and not with all the content.
I believe it is something of layout configuration, however I am beginner and I’m 3 days banging head with it. Any help would be welcome.
Follows the XML layout:
