CollapsingToolbar contentScrim не работает

Question

Я использую макет Координатора в макете ограничений и макете панели приложений вместе с CollapsingToolbarLayout, все работает нормально, кроме атрибута contentScrim.Это не работает так, как задумано.Когда я прокручиваю вверх, изображение все еще отображается на панели инструментов вместо того, чтобы показывать мой цвет.

Это работа для меня:

 <android.support.design.widget.CoordinatorLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <android.support.design.widget.CollapsingToolbarLayout
                android:id="@+id/myCollapse"
                app:title="Fizan"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:contentScrim="?attr/colorPrimary"
                app:layout_scrollFlags="scroll|exitUntilCollapsed">

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

Я надеюсь, что полезно для вас:)
