Question

我分别有两个微调器，它帮助我选择ListView生成的选项和标准，即我需要选择一个总线和一个停止来显示适合查询的时间表（ListView）。现在直接问题了：我在ScrollView和ListView本身有两个微调器。我需要确保，当设备水平翻转时，它会平滑滚动。我所能做的就是在固定高度滚动ListView，同时它可以填充并覆盖它的整个高度，但它会缩小......有什么想法吗？

请勿在{{1}}内使用ListView ...而是使用ScrollView并在ListView的顶部添加标题视图... http://developer.android.com/reference/android/widget/ListView.html#addHeaderView(android.view.View)

Here是我刚刚创建的示例。我希望它有所帮助...

如何使我的视图的一部分与ListView一起滚动？
