EditText getting shifted to bottom of layout

Question

I'm using appbarlayout in my app and when I include that layout in my main layout and place edittext below that layout my edittext is getting shifted to bottom. What I'm trying to do is setting edittext below toolbar but it is getting shifted at bottom of layout and also the floating action button is showing bit higher than it is showing in editor.

    android:layout_height="match_parent"
    android:id="@+id/coordinatorlayout">

            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            app:contentScrim="?attr/colorPrimary">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_height="?attr/actionBarSize"
                android:layout_width="match_parent"></android.support.v7.widget.Toolbar>
        </android.support.design.widget.CollapsingToolbarLayout>
    </android.support.design.widget.AppBarLayout>

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"></android.support.v4.widget.NestedScrollView>

    <android.support.design.widget.FloatingActionButton
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:src="@android:drawable/ic_input_add"
        android:layout_gravity="bottom|end"
        android:layout_margin="16dp"
        android:clickable="true" />
</android.support.design.widget.CoordinatorLayout>

And here I'm including it in main_activity

<ScrollView android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:fillViewport="true"
    android:fitsSystemWindows="true"
    xmlns:android="http://schemas.android.com/apk/res/android" >
<RelativeLayout 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"
    tools:context=".MainActivity"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:fitsSystemWindows="true">
    <include layout="@layout/toolbar_activity"
        android:id="@+id/toolbaractivity"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/toolbaractivity"/>
</RelativeLayout>
</ScrollView>

Use wrap_content for NestedScrollView's layout_height

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"></android.support.v4.widget.NestedScrollView>
