i'd add layout (pink rectangle) on yellow toolbar, intention of using hiding toolbar scrolling in futur.

toolbar , layout xml : 

<android.support.v7.widget.toolbar     xmlns:android="http://schemas.android.com/apk/res/android"     android:popuptheme="@style/appthemeaccueiltoolbar"     android:theme="@style/appthemeaccueiltoolbar"     android:id="@+id/toolbaraccueil"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:minheight="?attr/actionbarsize"     android:elevation="@dimen/toolbarelevation"     android:layout_margintop="@dimen/appbartopmargin"     >  </android.support.v7.widget.toolbar> <linearlayout     android:id="@+id/spinnerlayout"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:orientation="horizontal"     android:weightsum="99"     android:layout_below="@+id/toolbaraccueil">      <spinner         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/accueilanneespinner"         android:gravity="center"         android:layout_weight="33"         />      <spinner         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/accueilspinner"         android:gravity="center"         android:layout_weight="33"         />      <spinner         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/accueilmatierespinner"         android:gravity="center"         android:layout_weight="33"         />  </linearlayout>
