The current project I am currently working on has one screen we display a list of contents which you can scroll vertically and when user taps on the share button on content it loads a list of people with whom you can share the content.
Instead of opening a new screen/activity to show a list of people, I have shown a list of people on the same screen in the bottom. The list has pictures of people along with the name shown below those picture. The list can be scrolled horizontally.
Problem - I am not sure how to make horizontal obvious. There are several ways to do that but all of them has some sort of problem
Sol 1- Show the last item [picture+name] partially visible on the screen but that does look like a bug in the app.
Sol 2 - Give a arrow pointing on the right and when user taps on it, the list will scroll to the left but that it not natural. If something is horizontal scrollable people will scroll it horizontally by swiping horizontal
Or may be I am overthinking that people might not understand the horizontal scroll.
