Android 无法使工具栏折叠

更新问题。我尝试从strings.xml中的字符串数组设置适配器，然后将适配器设置为recyclerview（而不是从游标加载的适配器），但它仍然不起作用。我在这里再次发布了两个文件（activity\u article\u list.xml-主布局文件和ArticleListActivity.java）：

那些已经完成你的应用材料项目，请给我一些提示，如何添加一个功能齐全的折叠工具栏的主要活动

---

谢谢。

您是否已将整个视图包装在协调布局中？。e、 g

<android.support.design.widget.CoordinatorLayout >

    <android.support.design.widget.AppBarLayout >

        <android.support.design.widget.CollapsingToolbarLayout >

            <ImageView />

            <android.support.v7.widget.Toolbar />

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

    <android.support.v7.widget.RecyclerView />

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

我已经移除了参数

---

此滚动行为仅由CoordinatorLayout控制。任何其他容器都无法做到这一点。

请按照以下要求更改AppBarLayout代码…代码中缺少一些行…这对我来说非常适合

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="112dp"
    android:fitsSystemWindows="true"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:minHeight="?attr/actionBarSize"
        android:fitsSystemWindows="true"
        app:layout_scrollFlags="scroll|enterAlwaysCollapsed|enterAlways">

        <android.support.v7.widget.Toolbar
            android:id="@+id/anim_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/index6"
            android:fitsSystemWindows="true"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_collapseMode="pin"
            app:layout_scrollFlags="scroll|enterAlways">



        </android.support.v7.widget.Toolbar>
    </android.support.design.widget.CollapsingToolbarLayout>

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

使用此链接：是的，我已将其包装在coordinatorlayout中。请查看更新的问题以了解更多信息。您是否按照我的代码进行了操作？因为在代码中没有添加minHeight和layout，所以scrollFlags在CollasingToolbarLayout中也是不同的
