android – 在活动布局中使用Admob时的白色状态栏

我使用的布局层次结构是这样的：

<android.support.design.widget.CoordinatorLayout
...  >

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

        <android.support.design.widget.CoordinatorLayout
            ....
            android:layout_above="@+id/adView">

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

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

        <com.google.android.gms.ads.AdView
            android:id="@+id/adView"
            ... />

    </RelativeLayout>

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

因此,作为根的CoordinatorLayout,它确保状态栏颜色.

我想要实现的是通过将CoordinatorLayout和CoordinatorLayout嵌套作为活动布局的根元素来完成的.

我的布局文件的完整代码：

    <RelativeLayout

            android:layout_above="@+id/adView">

            <android.support.design.widget.AppBarLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:theme="@style/AppTheme.AppBarOverlay">

                <android.support.v7.widget.Toolbar

                    android:layout_height="?attr/actionBarSize"

                    app:layout_scrollFlags="scroll|enterAlways"
                    app:popupTheme="@style/AppTheme.PopupOverlay" />

                <android.support.design.widget.TabLayout
                    android:id="@+id/tabs"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" />

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

            <android.support.v4.view.ViewPager
                android:id="@+id/container"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:layout_behavior="@string/appbar_scrolling_view_behavior" />

            <android.support.design.widget.FloatingActionButton
                android:id="@+id/fab"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="end|bottom"
                android:layout_margin="@dimen/fab_margin"
                android:src="@drawable/btn_plus_add" />

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

        <com.google.android.gms.ads.AdView
            android:id="@+id/adView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            ads:adSize="SMART_BANNER"
            ads:adUnitId="@string/banner_ad_bottom_event" />

    </RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

它最终变成了这样：
