隐藏工具栏,CoordinationLayout和Webview不起作用

Question

我正在尝试使用新的CordinationLayout滚动WebView时隐藏工具栏,但它无法正常工作.有什么办法吗？这是我的xml:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.themobilebakery.isus.gui.WebViewActivity">

<WebView
    android:id="@+id/webview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

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


        <android.support.v7.widget.Toolbar
            android:id="@+id/webview_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:minHeight="0dp"
            app:layout_scrollFlags="scroll|enterAlways" />

        <ProgressBar
            android:id="@+id/webview_progress"
            style="?android:attr/progressBarStyleHorizontal"
            android:layout_width="match_parent"
            android:layout_height="3dp"
            android:progressDrawable="@drawable/isus_orange_progres_webview"
            app:layout_scrollFlags="scroll|enterAlways" />
    </android.support.design.widget.AppBarLayout>

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

您需要在webview中添加layout_behavior

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <WebView
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</android.support.v4.widget.NestedScrollView>
