Aktivität des Elements abdeckt Toolbar

Question

meine XML:

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:orientation="vertical"> 

<ProgressBar 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:id="@+id/progressBar" 
    android:layout_gravity="center_horizontal|top" 
    android:layout_marginTop="50dp" 
    android:indeterminate="true" 
    android:visibility="invisible" 
    android:layout_centerHorizontal="true" /> 

    <android.support.v7.widget.Toolbar 
     android:layout_height="wrap_content" 
     android:layout_width="match_parent" 
     android:minHeight="?attr/actionBarSize" 
     android:id="@+id/toolbarTab2" 
     app:theme="@style/ToolBarStyle" 
     android:elevation="5dp" 
     android:paddingTop="20dp" 
     android:textAlignment="center" 
     android:background="@android:color/holo_red_light"> 

     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="MY TOOLBAR TITLE" 
      android:layout_gravity="center" 
      android:id="@+id/toolbar_title" 
      android:textSize="20sp" 
      android:textStyle="bold" 
      android:background="#00000000" 
      android:textColor="#ffffff" /> 

    </android.support.v7.widget.Toolbar> 


    <android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/swipe_refresh_layout" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:foregroundGravity="left|right"> 




    <android.support.v7.widget.RecyclerView 

     android:id="@+id/notesList" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" 

     > 

    </android.support.v7.widget.RecyclerView> 


</android.support.v4.widget.SwipeRefreshLayout> 

</RelativeLayout> 

meiner Symbolleiste auf api 21 arbeitet gut und höher wegen Elevation aber auf api < 20 seine abgedeckt durch Aktivität des Elements (da sie unterstützen nicht Elevation), eine Idee wie das zu beheben ??

hier kann man sehen, dass mein Toolbar hinter dem cardview
