I was designing a profile page for my app in android Studio with recycler view(Vertical), where each row has its own layout and I load it using the Recycler view adaptor...The 3rd and 4th row of my recycler view are again another recycler view(Horizontal) and they displaying images using another adaptor. My problem is while I am scrolling my activity the 3rd and 4th row slow down the scrolling speed. How can I fix it?
Your problem does not have to be with the adapters, there has to be with the amount of information that the recycler is going to process.

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 really don't know how to describe my problem, but here is an image to show what am talking aboutImage
So judging from the image, the horizontal view with months is a recyclerview with the Layoutmanager set in horizontal, so when someone is scrolling through the months it continuously fetches the correct information/filters based on the month at the middle but do not know how to implement
You can implement those months using a view pager, and then implement a fragment for each month. Each fragment will have a recycler view and fragment will fetch the data and feed it into recycler view.
You can refer to this link for an example https://www.journaldev.com/12958/android-tablayout-viewpager

If the question is not clear please let me know
Thank you
I am trying to create a specific type of recycler view with following requirements:
1) RecyclerView that would show one item per screen (1 row will take the size of screen).
2) When I scroll the recyclerview it should stop scrolling as soon as the next item is visible. (Captures the whole screen).
Please tell me if that is possible or not.
Do you have to use RecyclerView?
Probably you can do that with View Pager.

I managed to implement a GalleryView, create a custom Adapter that returns a ListView for each item of the gallery but now the the problem:
I while I can scroll the listview vertially, I can no longer scroll the GalleryView horizontally.
What I am aiming at is a UI similar to the Google Weather/News application. While you can click a 'tab-like' gallery item on the top, you can also horizontally scroll the list views that represent the news items.
How can I implement this?
I don´t know the Google Weather/News app, but if I understand you correctly a ViewFlipper/ViewAnimator could help you.
