试试这个......

    <android.support.v7.widget.Toolbar 
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/primary"
        android:minHeight="?attr/actionBarSize"
        android:textAlignment="center"
        local:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" >

     <ViewStub
                    android:id="@+id/toolbar_view_stub"
                    android:layout_width="match_parent"
                    android:background="@color/primary"
                    android:layout_height="match_parent" />
     </android.support.v7.widget.Toolbar>

愿它有所帮助！

找到解决方案我必须在工具栏正下方添加一个空视图

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

        <android.support.v7.widget.Toolbar
            android:id="@+id/n_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:minHeight="?attr/actionBarSize"
            app:theme="@style/ToolbarColoredBackArrow">

            <ProgressBar
                android:id="@+id/progressBar"
                style="@style/wrap_wrap"
                android:visibility="gone"
                android:layout_gravity="end"
                android:indeterminate="true"
                android:padding="@dimen/defaultLayoutPadding" />

            <ViewStub
                android:id="@+id/toolbar_view_stub"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </android.support.v7.widget.Toolbar>
        <!-- The empty is used for fixing the empty blank header issue,please don't remove it -->
        <View
            android:layout_width="fill_parent"
            android:layout_height="1dp" />
    </android.support.design.widget.AppBarLayout>

滚动视图时，工具栏变为空白
