有没有办法用标题创建水平列表视图。我认为可以通过HorizontalScrollView组件创建水平列表视图。正如我提供的任务应用程序(http://i.stack.imgur.com/qWZPh.jpg)中所示,可以在购物清单中查看Grocery List和Work标题。当我从Grocery List转到Work时,标题也应该无缝移动。如何为这样的标题设置动画(以便在我们滚动列表时放置它们)?
谢谢

应用程序(您发布的屏幕截图,实际上我每天都在使用它)使用ViewPager和PagerTitleStrip。
如果您使用Eclipse,则会有一个默认选项来创建此类活动。
当我选择Swipe Views + Title Strip
时,Eclipse会自动生成以下XML代码。
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<!--
This title strip will display the currently visible page title, as well as the page
titles for adjacent pages.
-->
<android.support.v4.view.PagerTitleStrip android:id="@+id/pager_title_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#33b5e5"
android:textColor="#fff"
android:paddingTop="4dp"
android:paddingBottom="4dp" />
还要尝试检查:
