Used OnTouchListener for nested scrolling in ViewPager2
👋 👋 👋
This PR modifies the NestedScrollableHost to be a View.OnTouchListener
rather than a ViewGroup
that houses the nested scrolling child.
I don't think this is a better implementation per se, just more of a different one. I'm mostly curious about the design decisions that led to opting for nesting the scrollable child rather than using the View.OnTouchListener
.
Off the top of my head, I can see the View.onTouchListener
is a bit intrusive and limits custom touch interception on the nested scrollable View
, however this is mitigated if this View
were a RecyclerView
as it could use the RecyclerView.OnItemTouchListener
instead, which would be perfect for this example.
FWIW, this solution worked with nested ViewPagers, i.e I had ViewPager2
-> ViewPager2
-> HorizontalScrollView
where the middle ViewPager2
had isUserInputEnabled = false
and it worked a charm.
