推荐答案

如果你想获得一个列表，此行为，您应该：

If you would like to obtain a list with this behaviour, you should:

• 添加与设计支持库编译com.android.support:design:22.2.0
• 使用一个 CoordinatorLayout 有一个工具栏，你必须定义应用程序：layout_scrollFlags =滚动| enterAlways
• 使用一个的 RecyclerView 代替的ListView 。如上所述<一个href="http://stackoverflow.com/questions/30696611/design-lib-coordinatorlayout-collapsingtoolbarlayout-with-gridview-listview/30885092#30885092">here 的ListView 和的GridView 有预期的行为 CoordinatorLayout 只有API> 21。在这种情况下，你必须使用 setNestedScrollingEnabled（真）;

• add the design support library with compile 'com.android.support:design:22.2.0'
• Use a CoordinatorLayout with a Toolbar where you have to define app:layout_scrollFlags="scroll|enterAlways"
• Use a RecyclerView instead of a ListView. As described here ListView and the GridView have the expected behavior with the CoordinatorLayout only with API>21. In this case you have to use setNestedScrollingEnabled(true);

The official blog post shows this case:

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

     <! -- Your Scrollable View -->
    <android.support.v7.widget.RecyclerView
            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
                  ...
                  app:layout_scrollFlags="scroll|enterAlways">


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