Wie zu beheben Material Registerkarte Host in android 5+

Question

Ich verwendete (kompilieren 'it.neokree: MaterialTabs: 0,11') libariry Tab in meinem Projekt zu erstellen. Aber ich habe ein Problem. Wie Sie sehen, gibt es eine Lücke zwischen Tabs und AppBarLayout in Android 5 und höher. aber in Androiden mit der niedrigeren Version ist alles in Ordnung. Was ist das Problem?!?!?!

<android.support.design.widget.AppBarLayout 
    android:id="@+id/app_bar" 
    android:layout_width="match_parent" 
    android:layout_height="@dimen/_300sdp" 
    android:fitsSystemWindows="true" 
    android:theme="@style/AppTheme.AppBarOverlay"> 

    <android.support.design.widget.CollapsingToolbarLayout 
     android:id="@+id/toolbar_layout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:fitsSystemWindows="true" 
     app:contentScrim="@color/colorPrimary" 
     app:layout_scrollFlags="scroll|exitUntilCollapsed"> 

     <android.support.v7.widget.Toolbar 
      android:id="@+id/toolbar" 
      android:layout_width="match_parent" 
      android:layout_height="50dp" 
      app:layout_collapseMode="pin" 
      android:title="" 
      app:popupTheme="@style/AppTheme.PopupOverlay" > 

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

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

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

<it.neokree.materialtabs.MaterialTabHost 
    android:id="@+id/materialTabHost" 
    android:layout_width="match_parent" 
    android:layout_height="?attr/actionBarSize" 
    app:textColor="#ffffff" 
    android:layout_gravity="top" 
    android:layout_below="@id/app_bar" 
    app:primaryColor="@color/colorPrimary" 
    app:colorPrimaryDark="#dedede" 
    app:contentInsetStart="0dp" 
    app:contentInsetEnd="0dp" 
    app:accentColor="#ffffff" 
    app:tabGravity="fill" 
    app:tabMode="scrollable" 
    android:gravity="bottom" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    tools:context="ir.persianit.doctors.DetailActivity" 
    tools:showIn="@layout/detailsdoctors"/> 

<android.support.v4.view.ViewPager 
    android:id="@+id/pager" 
    android:layout_width="match_parent"

    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    tools:context="ir.persianit.doctors.DetailActivity" 
    tools:showIn="@layout/detailsdoctors"> 

</android.support.v4.view.ViewPager> 

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools"

    android:layout_height="match_parent" 
    android:layout_marginTop="?attr/actionBarSize" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    tools:context=".Main.DetailsActivity" 
    android:isScrollContainer="true"
