Problemi di rendering dopo dipendenze di gradle aggiornate

Question

Ho appena aggiornato depend.le build.gradle (Modulo: app) e in seguito ha avuto problemi di rendering su Android Studio. Ciò che è sbagliato, prima di aggiornare le dipendenze everythink funzionato correttamente

Ecco come è ora:

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile 'com.android.support:design:23.0.0' 
    compile 'com.android.support:appcompat-v7:23.0.0' 
    compile 'com.google.android.gms:play-services:7.8.0' 
    compile 'com.android.support:support-v4:23.0.0' 

    compile 'com.android.support:recyclerview-v7:23.0.0' 
} 

my_activity.xml

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:id="@+id/myLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true">

      android:background="@color/white" 
      android:layout_marginTop="4dp" 
      android:paddingTop="0dp" 
      app:layout_behavior="@string/appbar_scrolling_view_behavior" 
      android:id="@+id/myPager"/> 

     <android.support.design.widget.AppBarLayout 
      android:id="@+id/appBar" 
      android:layout_width="match_parent" 
      android:layout_height="120dp" 
      android:fitsSystemWindows="true"> 

      <android.support.design.widget.CollapsingToolbarLayout 
       android:id="@+id/collapsing_toolbar" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:fitsSystemWindows="true" 
       android:elevation="4dp" 
       app:contentScrim="?attr/colorPrimary" 
       app:expandedTitleMarginBottom="70dp" 
       app:expandedTitleMarginEnd="64dp" 
       app:expandedTitleMarginStart="48dp" 
       app:statusBarScrim="?attr/colorPrimary" 
       app:layout_scrollFlags="scroll|exitUntilCollapsed"> 

       <android.support.v7.widget.Toolbar 
        android:id="@+id/appToolbar" 
        android:layout_width="match_parent" 
        android:layout_height="?attr/actionBarSize" 
        app:layout_collapseMode="pin" /> 

       <android.support.design.widget.TabLayout 
        style="@style/AppTheme.TabLayout" 
        android:id="@+id/appTabs" 
        android:scrollbars="horizontal" 
        android:layout_gravity="bottom" 
        android:layout_width="match_parent" 
        android:layout_height="?attr/actionBarSize" 
        app:layout_scrollFlags="scroll|enterAlways" /> 
      </android.support.design.widget.CollapsingToolbarLayout> 
     </android.support.design.widget.AppBarLayout> 
</android.support.design.widget.CoordinatorLayout> 

ed ho ottenuto questo errore:

Rendering Problems Missing styles. Is the correct theme chosen for this layout?  

Use the Theme combo box above the layout to choose a different layout, or fix the theme style references. 

The following classes could not be instantiated: 
    - android.support.design.widget.CollapsingToolbarLayout (Open Class, Show Exception, Clear Cache) 

Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE

Clic sull'opzione'Sincronizzazione progetto con G Radle Files':

Se non funziona, provare a eseguire 'Rebuild progetto':
