Symbolleiste nicht in meinem Layout behoben - Xamarin.Droid

Question

Ich habe eine Klasse Include_toolbar für die Einstellung meiner Symbolleiste. Meine Symbolleiste wird in Ordnung gesetzt, aber wenn ich die Symbolleiste nach oben drücke, bewegt sie sich nach oben und verschwindet von meiner RecyclerView.

Was könnte das in meinem Layout bitte verursachen?

Attribut löschen app:layout_scrollFlags="scroll|enterAlways" von Toolbar.

Versuchen Sie folgendes:

<android.support.v7.widget.Toolbar 
     android:id="@+id/toolBar" 
     android:layout_width="match_parent" 
     android:layout_height="@dimen/notification_large_icon_height" 
     android:background="#B22222" 
     app:popupTheme="@style/ThemeOverlay.AppCompat.Light"> 

     <RelativeLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content"> 

      <TextView 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:id="@+id/counter_text" 
       android:textSize="20dp" 
       android:textColor="@android:color/white" 
       android:textStyle="bold" /> 
     </RelativeLayout> 
    </android.support.v7.widget.Toolbar>
