I am using Collapse On Scroll library and have replaced the list view with recycler view, but it does not scroll although the header effects are working. How do I make the recycler view scrollable
Can I have an example where recycler view touch/ scroll events are implemented?
Try this library
https://github.com/h6ah4i/android-advancedrecyclerview, I am guessing this should give you what you are looking for in terms of functionality and you can read through the library's code.

I am using recycler view with linear layout manager, based on some logic I am hiding/showing a view inside recycler view item.
Issue Problem occurs when I scroll, I can see some gaps in between recycler view item, which are random when scroll. If I hide the view always , then there is no issue, but I need to show and hide based on some logic and when implemented the gaps are coming as well.
Assumption One thing I am sure of is that the issue is there because of hiding/showing a view.
My question is why do wrap recycler view into nested scroll view
Does it relate to smooth scroll of recycler view
Actually i am creating app which fetch 2 images and the scroll of recycler view in that is very slow so should i wrap it into nested scroll view for smooth flow or compress images and store them
I am a bit confused on this topic ?
Wrapping Recycler view in scroll view is like a two sided blade. You should be careful about using it.
because when you use it, the recycler view will loose its advantage of recycling unneeded rows so at the same time you will have references to all those view, so if you have rows with many graphical item it will make problem for slow devices.
If you see putting the recycler view inside another nested scrollview solved your speed problem, It means you do a mess in the adapter of recycler view.
Do not do any heavy process in adapters and onBindViewHolder
I have one image view and list view in my XML file.
Functionality Required: When I scroll list view then image view should also scroll with slow scrolling speed.
You need to add parallax view inside a list-view instead of using image-view.
It's called Parallax Effect.
You can use this library
Use the android-design library wich already integrates the parallax effect. You can take a look at Chris Banes cheesesquare example to show how to do it.
I can not use android gallery view since it is deprecated. I need to implement it using horizontal scroll view. but there is no view recycling ability default. can any one suggest how can I implement it with view recycling functionality.
You should Go with ViewPager. i.e android.support.v4.view.ViewPager
1) It Help you to get Horizontal Scroll Swipe
2) It also Recycle the View as you wanted

Hope this is HelpFul...
Why is it when I insert a list view into a scrollview, the list view stops scrolling.
The Scroll View scrolls normally, but the list view seems as if it is frozem
Well it seems that you must not place a list view inside a scroll view, because the system will not know which control to scroll!
There is no need to add listview in scrollview since scrolling is a default property for
ListView. That is all.
Please go through the Android documentation before design any of the UI.
