Android 工具栏没有'；t在抽屉布局中滚动recyclerview时隐藏

您好，我试图隐藏工具栏时，我滚动recyclerview这是在片段，我的布局也有一个抽屉布局和表格布局。我只是想隐藏工具栏并向上移动选项卡栏

我已经尝试了在Stack overflow中找到的大多数答案，但仍然无法完成。我做错什么了吗？请有人在一周内帮我解决这个问题。

你能详细说明出了什么问题吗？我在这里看到的最大问题是在折叠工具栏布局的

layout\u滚动标记上设置了
exituntilclopsed
标记。如果您无法使工具栏从屏幕上滚动，这就是罪魁祸首。您的AppBarLayout需要如下设置：

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary">

    <android.support.design.widget.CollapsingToolbarLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:contentScrim="?attr/colorPrimary"
        app:titleEnabled="false"
        app:layout_scrollFlags="scroll">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin" />
    </android.support.design.widget.CollapsingToolbarLayout>

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

这是我找到的解释AppBarLayout和CollasingToolbarLayout的所有不同滚动标志的最佳资源：

非常感谢您。我删除了CollasingToolbarLayout，它工作了。我当前的活动_main.xml如下所示。我可以添加一个晶圆厂并将其隐藏在卷轴上。尝试在coordinatorLayout下添加晶圆厂，但在我滚动recyclerview时它不会隐藏。
