In my app I have a fragment with horizontal ViewPager and horizontal RecycleViews that sits under vertical ScrollView. My problem is that the ViewPager is blocking the parent vertical scroll. I tried to disable ViewPager vertical touch event, but it didn't help.
Here is a video that shows the problem:

Use a CoordinatorLayout instead of Scrollview, put the view-pager inside the CollapsingToolbarLayout and the rest of the layouts in the nestedScrollView.

You are using LinearLayout then you can set
android:weightSum
property for resolving this issue.

In my activity XML I have a Collapsing toolbar and, after that, an referring to my other XML where I have a NestedScrollView.
This is an image of the collapsing toolbar when it is NOT collapsed.
When I scroll up, it becomes collapsed and the NestedSrollView appears like this:
I want it to scroll just to some point like this and after that the user cannot scroll more:
How can I achieve this?

So, in this layout as you can see I want to add a TabLayout and a ViewPager below some views. Now the problem I am facing is my ViewPager is restricted to the available space at the bottom of the screen so, only the viewpager is scrollable and not the full activity layout. Which leaves very little space at the bottom to see the viewpager contents.
So, I want to make the whole layout below the appbar scrollable from the top so that the fragments inside viewpager are easily and conveniently visible.
------------Update---------
I tried using the Nested Scroll View, setFillViewPort, and the collapsing layout as suggested but still getting the same result.
Updated layout xml with Collapsing ToolbarLayout -

The nested scroll views I copied from - https://github.com/TheLittleNaruto/SupportDesignExample/tree/master/app/src/main/java/com/thelittlenaruto/supportdesignexample/customview
Now, the viewpager is scrolling but my actionbar title is not visible anymore.
Can someone suggest any changes to this layout that could fix this issue ?
I have tried to refine your code and if I am not wrong you wanted it to be scrollable,you can try the following code.

I have made minor changes.
Try not to use weights when using scrollView.As they don't work so
well with each other.
I have wrapped Tab layouts in a Linear Layout
and gave it static height(can be replaced easily).
Hope it helps.
I have this layout:
<android.support.v4.widget.NestedScrollView
android:id="#+id/scrollview"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<--There is some layouts here-->
<RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
It works well. I can scroll RecyclerView smoothly without scrolling parent view.
Now I have to put the RecyclerView inside a FrameLayout like this:
<android.support.v4.widget.NestedScrollView
android:id="#+id/scrollview"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<--There is some layouts here-->
<FrameLayout
android:id="#+id/review_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<include
android:id="#+id/empty_view"
layout="#layout/review_empty_view"
android:visibility="gone" />
</FrameLayout>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
Now I cannot scroll the RecyclerView smoothly.
All I want is: scroll RecyclerView smoothly without scrolling parent view. What should I do?
EDIT: Here is my review_empty layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal"
android:padding="16dp">
<ImageView
android:layout_width="80dp"
android:layout_height="80dp"
android:src="#drawable/shopping_review_empty" />
<android.support.v4.widget.Space
android:layout_width="32dp"
android:layout_height="0dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/shopping_no_review_message" />
</LinearLayout>
just enable nestedscrolling that will enable smooth scrollview.
RecyclerView v = (RecyclerView) findViewById(...);
v.setNestedScrollingEnabled(false);
Use this in your recyclerView
app:layout_behavior="#string/appbar_scrolling_view_behavior"
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout

Try this...
I am suggesting you to do like this. When you get Empty Data then just set Recycler View Visibility as Gone and set Empty View Visibility as Visible.

That may be a chance you loading images(static) in to ImageView can be slow your recyclerView.
Or Big size of image.
Try to run application on mobile have good size of RAM
Add fillViewport is true in NestedScrollView in xml file as below:
<android.support.v4.widget.NestedScrollView
android:id="#+id/nestedScrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:scrollbars="none">
And In your activity setNested scrolling false as below code
recycler_view.setNestedScrollingEnabled(false);
Just put your "not scrollable" layout outside the nested scroll view
All you have to do is use below line in your activity class:
ViewCompat.setNestedScrollingEnabled(recycler_view, false);
its compatible for lower versions also. and if you want to give compatible to API >21 only then use;
recycler_view.setNestedScrollingEnabled(false);
i use CoordinatorLayout , AppBarLayout , CollapsingToolbarLayout, ViewPager all inside RelativeLayout parent.
Before I scroll the list ViewPager (include recyclerview inside fragment), scroll on CollapsingToolbarLayout good working. But when I first scroll on the ViewPager, and again scroll on CollapsingToolbarLayout not working.!! why?
I want scroll on viewpager and scroll on CollapsingToolbarLayout. CollapsingToolbarLayout not scrollable :|

I have a CoordinatorLayout with an AppBarLayout and a CollapsingToolbarLayout. In CollapsingToolbarLayout I'm using a LinearLayout showing user info as a layout_collapseMode=parallax element, below of it, a TabLayout.
The behaviour that I expect is a smooth hiding of the user info while the TabLayout is scrolling up or down.
The problem is that the items positions are reset when I scroll down a bit, hiding entirely the user info layout.
