    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:focusableInTouchMode="true"
            android:orientation="vertical">

            <include layout="@layout/banner_layout" />

            <android.support.v7.widget.RecyclerView
                android:id="@+id/list"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />

        </LinearLayout>

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

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

       <Appbarlayout>

              <Toolbar>

               app:layout_scrollFlags="scroll|snap"/>

       <Relative Layout>

             app:layout_scrollFlags="scroll|snap"/>

           <ImageView>

Avoid nested scrolling whenever possible . You can design layout like this:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout 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"
    android:orientation="vertical">

            <android.support.v7.widget.RecyclerView
                android:id="@+id/list"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
</android.support.v4.widget.SwipeRefreshLayout>

You can define data of adapter like this 

.............
List<Object> objects=new ArrayList<>()
object.add(new ImageData('Image url'))
object.add(new Data('title','subtitle','date'))
.............

Since RecylerView adapter supports different viewTypes you can use first position of adapter as header view type and rest normal view type.
For that you can refer to this ans Is there an addHeaderView equivalent for RecyclerView?
For a dynamic header, you can create a method like :

----
setHeaderAvailable(boolean isHeaderAvailable){
  this.isHeaderAvailable=isHeaderAvailable
}
----

and adapter data will look like this:

---
  List<Object> objects=new ArrayList<>()
  if(imageUrl!=null){
  adapter.setHeaderAvailable(true)
  object.add(new ImageData('Image url'))
}else{
  adapter.setHeaderAvailable(false)
}
   object.add(new Data('title','subtitle','date'))
--

and update getItemViewType method like this:

----
@Override
public int getItemViewType(int position) {
     if (isPositionHeader(position) && isHeaderAvailable)
            return TYPE_HEADER;

        return TYPE_ITEM;
 }

You have set this property before setAdapter

recyclerView.setNestedScrollingEnabled(false);

replace your RecyclerView with this one..

<android.support.v7.widget.RecyclerView
            android:id="@+id/list"
            android:layout_width="match_parent"
            android:layout_height="200dp" />
