我搜索了网络找到我的下面的问题的答案。但没有找到答案。我自己尝试了几种方法，但我仍然是Android的新手。我净相关滚动发现是官方文档和滚动的http://developer.android.com的例子，Senthilkumar先生的How to scroll the screen，Kakka47的ScrollView only part of the screen，darrinps A scroll view with only part of the screen scrolling等Android要使可见屏幕的一部分滚动
这是很常见的要求，因为从以上技术职称清楚。我有如下图所示的屏幕布局。
从顶部到栏目标题的屏幕是稳定的。表格记录，列标题下方需要滚动。我有AbsoluteLayout（我知道它已被弃用，但这是我可以用于特定需求的唯一一个），它内部是scrollview，内部scrollview是TableLayout。
用户点击“添加”按钮添加收到的订单。一行一行。随着行数的增加，它们超出可见区域。因此，我希望它滚动以便用户可以访问它。但这部分不滚动。我已经列出了我的代码。请告诉我应该怎么做。

我先试了。当它不起作用，那么我已经从http://code.google.com/p/iosched/source/browse/android/src/com/google/android/apps/iosched/ui/widget/ObservableScrollView获取了ObservableScrollView类.java –
