Android设计支持导航抽屉巨大的actionbar

我正在实现design support navigation drawer并使其正常工作，但问题是工具栏现在很大，它扩展到整个活动高度

我正在使用的代码： 主要活动：

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:fitsSystemWindows="true">

    <include android:id="@+id/toolbar" layout="@layout/toolbar" />

    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_height="match_parent"
        android:layout_width="wrap_content"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/navigation_header"
        app:menu="@menu/drawer_view"/>

</android.support.v4.widget.DrawerLayout>

主内容视图必须是

抽屉布局中的第一个子视图，因此您必须将
活动\u main
布局更改为：

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:fitsSystemWindows="true">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <include android:id="@+id/toolbar" layout="@layout/test_toolbar" />

    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_height="match_parent"
    android:layout_width="wrap_content"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/navigation_header"
    app:menu="@menu/drawer_view"/>

</android.support.v4.widget.DrawerLayout>

谢谢，这确实解决了问题
