Question

我在滚动浏览内容时尝试修复工具栏。滚动时，当前工具栏会消失。我试过这个solution，但我没有设法让它发挥作用。到目前为止，我还没有解决方法。任何帮助将不胜感激。这是我的XML布局和相关布局的图片。

已经有一段时间了，但我设法解决了，所以这里是代码：

    <android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/app_bar_height">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin"
            app:layout_scrollFlags="scroll|enterAlways"
            app:title="Title" />

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/toolbar_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            app:expandedTitleTextAppearance="@style/TextAppearance.AppCompat.Title">

            <!-- Action bar content -->

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

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

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

        <!-- scrollable content -->

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


    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ... />

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