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.
Updated layout

NestedScrollView issue with RecyclerView

When we use RecyclerView inside NestedScrollView app stuck where we call notifyDatasetChanged or notify inserted , it is because of when we call notify it is calling all item at same time ("it called onBindViewHolder at same time") so is there any solution to solve this issue?
If I remove NestedScrollView it work but we can't use multiple layout("example 2 RecyclerView ")

Change viewpager height
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />

in your xml activity_subcategory.xml
change parent Linear layout
<LinearLayout
android:id="#+id/main_layout"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="fill_parent">
change height to fill parent.

Use this code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_gravity="center"
android:gravity="center"

android:layout_height="match_parent"
android:id="#+id/rcv"
android:layout_gravity="center"
android:foregroundGravity="center">
</android.support.v7.widget.RecyclerView>

for view pager use fill parent

xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/viewPager"

android:layout_height="fill_parent"
/>

Add floating button on a CardView and RecyclerView

I have this problem to accommodate my floating button, and I do not understand why it does not work.
I would appreciate your response since I can not find the reason why this is happening, one more detail when scrolling or reloading the fragment some of the floating buttons will be accommodated.
And sorry for my English.
<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="wrap_content"
android:background="#color/colorBackground"
android:orientation="vertical">
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v7.widget.CardView
android:id="#+id/mRequestCard"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:elevation="100dp"
android:orientation="horizontal"
app:cardBackgroundColor="#color/colorWhite"
app:cardCornerRadius="3dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<View
android:id="#+id/vDivisor"
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#color/colorGreen" />
...
</RelativeLayout>
</android.support.v7.widget.CardView>
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginRight="#dimen/fab_margin"
android:backgroundTint="#color/colorPurple"
android:scaleType="centerCrop"
android:src="#drawable/ic_route_direction"
app:layout_anchor="#id/mRequestCard"
app:layout_anchorGravity="right|end|bottom" />
</android.support.design.widget.CoordinatorLayout>
And this is my RecyclerView Which is inflated in a fragment
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.test.HistorialFragment">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/mRecyclerRequest"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</FrameLayout>
And this is my fragment, where I show the RecyclerView
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.test.MainActivity"
tools:showIn="#layout/app_bar_main">
</FrameLayout>

you should try RelativeLayout like this
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:backgroundTint="#color/colorBlack"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"/>
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cardCornerRadius="#dimen/activity_corner"
android:layout_marginBottom="#dimen/activity_margin">
<!--your cardview item here-->
</android.support.v7.widget.CardView>
</RelativeLayout>
for your RecyclerView item

Check if this helps you:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="wrap_content"
android:background="#color/colorPrimary"
android:orientation="vertical">
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v7.widget.CardView
android:id="#+id/mRequestCard"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:elevation="100dp"
android:orientation="horizontal"
app:cardBackgroundColor="#color/colorWhite"
app:cardCornerRadius="3dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<View
android:id="#+id/vDivisor"
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#color/colorGreen" />
...
</RelativeLayout>
</android.support.v7.widget.CardView>
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:layout_marginRight="10dp"
android:backgroundTint="#color/colorAccent"
android:scaleType="centerCrop"
android:src="#drawable/ic_launcher"
app:layout_anchor="#id/mRequestCard"
app:layout_anchorGravity="right|end|bottom" />
</RelativeLayout>

try this use RelativeLayout and make your FloatingActionButton property android:layout_alignParentBottom="true" and
android:layout_alignParentRight="true" like below code
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:backgroundTint="#color/colorBlack"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"/>
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cardCornerRadius="#dimen/activity_corner"
android:layout_marginBottom="#dimen/activity_margin">
</android.support.v7.widget.CardView>
</RelativeLayout>

How to use RecyclerView inside NestedScrollView

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
android:id="#+id/review_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
</ScrollView>
<include
android:id="#+id/empty_view"
layout="#layout/review_empty_view"
android:visibility="gone" />
</FrameLayout>
</LinearLayout>
</LinearLayout>
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.
Here is Code :

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);
