Moving Android-Layouts

Question

Ich habe eine App-Leiste am oberen Rand des Bildschirms, und ich habe ein lineares Layout mit zwei Tasten und einem TextView. Dieses lineare Layout ist innerhalb der Werkzeugleiste und ich kann nicht herausfinden warum.

    android:id="@+id/appbar" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:paddingTop="@dimen/appbar_padding_top" 
    android:theme="@style/AppTheme.AppBarOverlay"> 


    <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar"

     /> 
    <TextView 
     android:layout_height="match_parent" 
     android:layout_width="wrap_content"

     android:id="@+id/dateBox"

    <ImageButton 
     android:layout_height="20dp" 
     android:layout_width="20dp" 
     android:background="@drawable/arrow_right" 
     android:id="@+id/rightDateButton" 
     /> 
</LinearLayout> 

<android.support.v4.view.ViewPager 
    android:id="@+id/container" 
    android:layout_width="match_parent" 
    android:layout_height="563dp" 

    app:layout_behavior="@string/appbar_scrolling_view_behavior" /> 

</android.support.design.widget.CoordinatorLayout> 

Sie können an der Spitze die beiden Pfeile in der Bar sehen. Ich versuche, die unter der Bar zu bekommen.
