Question

我正在尝试获得此设计，但是内容没有崩溃。滚动时，我需要选项卡位于工具栏下方。当前，我设置了两个按钮来折叠布局以进行测试，但是现在内容尚未滚动。我究竟做错了什么？也许我应该在CoordinatorLayout之外添加工具栏？

Answer 1

如果不想使Toolbar粘滞，请尝试此操作，这意味着它将与CollapsingToolbar一起折叠。

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_marginTop="@dimen/appBarTopMargin"
    android:elevation="@dimen/toolbarElevation"
    app:layout_scrollFlags="scroll|exitUntilCollapsed"  <== Add this line 
    app:contentInsetStart="0dp"
    tools:ignore="UnusedAttribute">

如果您希望Toolbar保持粘性。然后，将Toolbar从主CoordinateLayout中移出。
