Android NestedScrollView align content on top -


i noticed content in nestedscrollview inside coordinatorlayout aligns on bottom if not fill entire screen. how can fix that?

my code:

<android.support.design.widget.coordinatorlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     xmlns:card_view="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:fitssystemwindows="true">      <android.support.design.widget.appbarlayout         android:id="@+id/appbar"         android:layout_width="match_parent"         android:layout_height="140dp"         android:theme="@style/themeoverlay.appcompat.dark.actionbar"         android:fitssystemwindows="true">          <android.support.design.widget.collapsingtoolbarlayout             android:layout_width="match_parent"             android:layout_height="match_parent"             android:fitssystemwindows="true"             app:layout_scrollflags="scroll|exituntilcollapsed"             app:contentscrim="?attr/colorprimary"             app:expandedtitlemarginstart="48dp"             app:expandedtitlemarginend="64dp">              <android.support.v7.widget.toolbar                 android:layout_width="match_parent"                 android:layout_height="?attr/actionbarsize"                 app:popuptheme="@style/themeoverlay.appcompat.light"                 app:layout_collapsemode="pin" />          </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_anchorgravity="top|start"         app:layout_behavior="@string/appbar_scrolling_view_behavior">          <linearlayout             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:paddingtop="24dp"             android:orientation="vertical">              <android.support.v7.widget.cardview                 android:layout_width="match_parent"                 android:layout_height="200dp"                 android:layout_margintop="10dp"                 android:layout_marginleft="10dp"                 android:layout_marginright="10dp"                 card_view:cardbackgroundcolor="@color/white"                 card_view:cardelevation="2sp"                 card_view:cardusecompatpadding="true">              </android.support.v7.widget.cardview>              <listview                 android:layout_height="match_parent"                 android:layout_width="match_parent"                 android:layout_margintop="10dp"                 android:divider="@color/black_200"                 android:dividerheight="-7dp"                 android:listselector="@android:color/transparent"                 android:cachecolorhint="@android:color/transparent" />          </linearlayout>      </android.support.v4.widget.nestedscrollview>      <android.support.design.widget.floatingactionbutton         android:layout_height="wrap_content"         android:layout_width="wrap_content"         android:src="@drawable/ic_navigate"         android:layout_margin="16dp"         app:backgroundtint="@color/accent_yellow"         app:borderwidth="0dp"         app:elevation="8dp"         app:pressedtranslationz="12dp"         app:fabsize="normal"         app:ripplecolor="@color/accent_dark_yellow"         app:layout_anchor="@id/appbar"         app:layout_anchorgravity="bottom|right|end"/>  </android.support.design.widget.coordinatorlayout>

as can see, cardview inside nestedscrollview 200dp high, , aligns on bottom.

use following property in android.support.v4.widget.nestedscrollview

android:layout_gravity="fill_vertical"
