  So you are saying the recyclerView is occupying half of the phone's screen width?

  Use this View view=layoutInflater.inflate(R.layout.recyclerview_items,viewGroup,false); instead of this View view = layoutInflater.inflate(R.layout.recyclerview_items, null);

  So you are saying the recyclerView is occupying half of the phone's screen width?

  Use this View view=layoutInflater.inflate(R.layout.recyclerview_items,viewGroup,false); instead of this View view = layoutInflater.inflate(R.layout.recyclerview_items, null);

                    myfilterList.add(pos+1, new Model("dummy"));

                    notifyItemChanged(pos+1);

                    notifyDataSetChanged();

                }

Try changing the RecyclerView element inside your activity_main.xml file with the following, remove center_in_parent and change android:layout_height="wrap_content"

<?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"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity">



    <android.support.v7.widget.SearchView

        android:id="@+id/search"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:background="@color/colorPrimaryDark"

        android:focusable="false"

        android:visibility="gone"

        app:iconifiedByDefault="false"

        app:queryHint="Search Distributors..." />



    <android.support.v7.widget.RecyclerView

        android:id="@+id/recyclerView"

        android:layout_width="match_parent"

        android:layout_below="@+id/search"

        android:layout_height="wrap_content" />



    <Button

        android:id="@+id/btnGet"

        android:visibility="gone"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_marginTop="10dp"

        android:layout_alignParentBottom="true"

        android:text="get" />





</RelativeLayout>

Edit 1 - Using ConstraintLayout, since after the RecyclerView you'd also like to display the button, you will need the ConstraintLayout inside the NestedScrollView

<?xml version="1.0" encoding="utf-8"?>

<android.support.v4.widget.NestedScrollView 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="match_parent">

<android.support.constraint.ConstraintLayout 

    android:layout_width="match_parent"

    android:layout_height="wrap_content">



    <android.support.v7.widget.SearchView

        android:id="@+id/search"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        app:layout_constraintTop_toTopOf="parent"

        android:background="@color/colorPrimaryDark"

        android:focusable="false"

        app:iconifiedByDefault="false"

        app:queryHint="Search Distributors..." />



    <android.support.v7.widget.RecyclerView

        android:id="@+id/recyclerView"

        android:layout_width="match_parent"

        app:layout_constraintTop_toBottomOf="@+id/search"

        android:layout_height="wrap_content" />



    <Button

        android:id="@+id/btnGet"

        app:layout_constraintBottom_toBottomOf="parent"

        app:layout_constraintTop_toBottomOf="@+id/recyclerView"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_marginTop="10dp"

        android:layout_alignParentBottom="true"

        android:text="get" />





</android.support.constraint.ConstraintLayout>

</android.support.v4.widget.NestedScrollView>

I don't have privileges to add a comment, hence posting it here. Sorry in advance.
Your question is not quite clear, do you want your RecyclerView to occupy the whole screen(i.e. parent). If that's the case, With LinearLayout I guess if you add an attribute android:layout_weight in your RecyclerView will solve the problem.
Here's what the discription for the attribute on developer.android site:

LinearLayout also supports assigning a weight to individual children with the android:layout_weight attribute. This attribute assigns an "importance" value to a view in terms of how much space it should occupy on the screen. A larger weight value allows it to expand to fill any remaining space in the parent view. Child views can specify a weight value, and then any remaining space in the view group is assigned to children in the proportion of their declared weight. Default weight is zero.

Hope this link helps https://developer.android.com/guide/topics/ui/layout/linear

Also there's this question already asked by me : What is the connection between setVisibility and layout_weight in Linear Layout

Correct me if I'm wrong.

In your adapter where you are inflating the item in onCreateViewHolder, use this code block:

View rootView = LayoutInflater.from(context).inflate(R.layout.itemLayout, null, false);

RecyclerView.LayoutParams lp = new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

rootView.setLayoutParams(lp);

return new RecyclerViewHolder(rootView);

Try changing the RecyclerView element inside your activity_main.xml file with the following, remove center_in_parent and change android:layout_height="wrap_content"

<?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"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity">



    <android.support.v7.widget.SearchView

        android:id="@+id/search"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:background="@color/colorPrimaryDark"

        android:focusable="false"

        android:visibility="gone"

        app:iconifiedByDefault="false"

        app:queryHint="Search Distributors..." />



    <android.support.v7.widget.RecyclerView

        android:id="@+id/recyclerView"

        android:layout_width="match_parent"

        android:layout_below="@+id/search"

        android:layout_height="wrap_content" />



    <Button

        android:id="@+id/btnGet"

        android:visibility="gone"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_marginTop="10dp"

        android:layout_alignParentBottom="true"

        android:text="get" />





</RelativeLayout>

Edit 1 - Using ConstraintLayout, since after the RecyclerView you'd also like to display the button, you will need the ConstraintLayout inside the NestedScrollView

<?xml version="1.0" encoding="utf-8"?>

<android.support.v4.widget.NestedScrollView 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="match_parent">

<android.support.constraint.ConstraintLayout 

    android:layout_width="match_parent"

    android:layout_height="wrap_content">



    <android.support.v7.widget.SearchView

        android:id="@+id/search"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        app:layout_constraintTop_toTopOf="parent"

        android:background="@color/colorPrimaryDark"

        android:focusable="false"

        app:iconifiedByDefault="false"

        app:queryHint="Search Distributors..." />



    <android.support.v7.widget.RecyclerView

        android:id="@+id/recyclerView"

        android:layout_width="match_parent"

        app:layout_constraintTop_toBottomOf="@+id/search"

        android:layout_height="wrap_content" />



    <Button

        android:id="@+id/btnGet"

        app:layout_constraintBottom_toBottomOf="parent"

        app:layout_constraintTop_toBottomOf="@+id/recyclerView"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_marginTop="10dp"

I don't have privileges to add a comment, hence posting it here. Sorry in advance.
Your question is not quite clear, do you want your RecyclerView to occupy the whole screen(i.e. parent). If that's the case, With LinearLayout I guess if you add an attribute android:layout_weight in your RecyclerView will solve the problem.
Here's what the discription for the attribute on developer.android site:

LinearLayout also supports assigning a weight to individual children with the android:layout_weight attribute. This attribute assigns an "importance" value to a view in terms of how much space it should occupy on the screen. A larger weight value allows it to expand to fill any remaining space in the parent view. Child views can specify a weight value, and then any remaining space in the view group is assigned to children in the proportion of their declared weight. Default weight is zero.

Hope this link helps https://developer.android.com/guide/topics/ui/layout/linear

Also there's this question already asked by me : What is the connection between setVisibility and layout_weight in Linear Layout

Correct me if I'm wrong.

In your adapter where you are inflating the item in onCreateViewHolder, use this code block:

View rootView = LayoutInflater.from(context).inflate(R.layout.itemLayout, null, false);

RecyclerView.LayoutParams lp = new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

rootView.setLayoutParams(lp);

return new RecyclerViewHolder(rootView);
