I am unable to scroll nestedScrollView because of viewpager. So let me explain here is layout design that i want to create:
There is FrameLayout inside NestedScrollView and a viewpager with tab layout. Viewpager load three fragments with endless recylerview (Pagination).
Here is layout xml code :

Now when i scroll outside of viewpager nothing happened (view not scroll). And on viewpager scroll only recyclerview scroll. But I want to scroll the whole view on outside frame layout scroll and on recylerview also.
What I have tried :
1) Set fixed height for Viewpager(700dp). Result: Scroll on Framelayout smoothly worked but Scroll on Recyclerview is not worked correctly and smooth. I have to scroll many time to scroll.
2) Set Framelayout & Tablayout inside AppBarLayout. Result: Scroll Up worked smoothly but On Scroll down Recylerview(Viewpager), first Appbarlayout is fully scrolled down and then Recyclerview content scrolled that was behind Appbarlayout. So I have to scroll down the whole list to see first contents it is a bad experience.
3.) Created custom Viewpager as suggested here like enter link description here Result : Same as 1st case:
4) Disabled Touch on Viewpager and use custom Viewpager. Result: Smoothly scrolled whole view but due to touch disabled on Viewpager I am unable to paginate Recyclerview means have to check every touch type and detect the end of the scroll to load next data in Recyclerview. I do not want to do this.
So here is my problem. Please if anybody has solution or cretaed somthing like this please help. Thanks in advance.
回答1:
So I have finally resolved this problem by just creating Custom Viewpager as mentioned here: Custom ViewPager that calculate ViewPager height and setNestedScrollingEnable(false) to RecyclerView inside Viewpager. By setting NestedScrollingEnalbe = false Recyclerview does set parent NestedScrollView's scroll. So Parent NestedScrollView works with inside Viewpager.
