I added NestedScrollView into my fragment as following code snippet.
I'm using FragmentPagerAdapter to display fragment content in ViewPager. (following this article)
Content is populating properly but I'm not able to scroll.
main_fragment.xml
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">

I'm able to scroll recycler view (not nestedscrollview) if I remove recyclerView.setNestedScrollingEnabled(false);

SCREENSHOT
As seen in screenshot view pager is set fixed on top and recycler view is scrolling below. I want to scroll view pager also some one please let me know how can I achieve desired layout. Any help would be appreciated.
THANKS
Replace your recyclerView with,
<android.support.v7.widget.RecyclerView
android:id="#+id/recycle"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
here,
app:layout_behavior="#string/appbar_scrolling_view_behavior"
will manage the rest of things.
Just add app:layout_behavior="#string/appbar_scrolling_view_behavior" in your NestedScrollView to scroll its child layouts and also remove android:scrollbars="none" from NestedScrollView.
To scroll the whole layout all we need to wrap nested scroll view under swipe refresh layout and this will scroll the whole layout.

How to use RecyclerView inside NestedScrollView? RecyclerView content is not visible after setting adapter.
Anyway, I have already tried with RecyclerView inside NestedScrollView by adding a viewgroup like framelayout or relativelayout as a single child of nestedscrollview and then I added a recyclerview inside framelayout or relativelayout)
Thanks in Advance...

</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
Replace your RecycleView with this...
<com.app.view.CustomRecyclerView
android:id="#+id/rv_driverRequests"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:fillViewport="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
Hope this will work.

My Recycler view scrolls,even without collapsing toolbar sometimes.Alsothe scrolling is not smooth.In recyClerView of view pager i have a header item and then the list of items.Sometimes it get stuck at Header at top and need to pull it down.
For every RecyclerView that is has a scrolling parent (such as ScrollView or NestedScrollView) you should disable nested scrolling like this:
yourRecyclerView.setNestedScrollingEnabled(false);
For your smoothing problem it seems that there is a bug with AppBarLayout and there are some libraries for fixing that. One that I know but I've never used is:
https://github.com/henrytao-me/smooth-app-bar-layout
I have to implement viewpager with headerview and Collapsible Toolbar. I have implemented that but currently scroll only works on viewpager view not on the headerview.
Please let me know the way to fix this issue.
Here is my layout.

your TabLayout like headerview. try this sample. the sample implemented viewpager and tablayout & collapsingtoolbarlayout.
I'm trying to do something like this:
I currently have the above layout without the header implemented. All I need is to figure out how to add the header.
Here is the header layout I want to put above the tabs:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center_horizontal"
android:background="#color/green">
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:background="#drawable/ic_image"
android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:layout_gravity="center_vertical" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hey!"
android:textColor="#color/white"
android:textSize="24sp"
android:layout_gravity="center_vertical" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
I use a RecyclerView for the content below the tabs. I use 3 different Fragments for the Activity.
Here is my Activity:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:elevation="0dp">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar_group"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="0dp"
android:background="#color/blue"
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabTextAppearance="#style/TabLayout"
app:tabSelectedTextColor="#color/white"
app:tabTextColor="#color/white"
/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
</android.support.design.widget.CoordinatorLayout>
And here is one of my Fragments:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.design.widget.CoordinatorLayout>
How can I add the header above the TabLayout and keep normal scrolling behaviors?
You just need a RecyclerView to do that.
Combine your header and tabLayout to a Header view, then add to your RecyclerView.
Check https://github.com/u3breeze/android-RecyclerView-WithHeaderAndFooter. I did a extension of RecyclerView.Adapter. Easy to add header and footer to RecyclerView.
