Android：即使视图滚动，如何将广告对齐到屏幕底部？

之前我问过一个问题，至今没能解决：

http://stackoverflow.com/questions/3126347/android-relativelayout-how-to-alignparentbottom-when-wrapped-in-a-scrollview

我想要做的是将视图与屏幕底部对齐，使用RelativeLayout或LinearLayout，然后将该布局包装在滚动视图中以允许在必要时滚动（用于更改横向方向或在小屏幕设备上）。

到目前为止，我发现只要底部可见，任何与父底部对齐的内容都可以很好地工作......但是如果底部位于滚动条下方，则与父底部对齐的视图会跳到顶部。

对于出现在底部的广告来说，这似乎是一种非常常见的设计，所以我认为这是可能的。是吗？

我不知道是否有一种方法可以做到这一点，但这是我用来做这种事情的一个技巧。如果这是你想要的：

这是我的代码：

我希望这符合您的希望；）这只是一个带有边距的技巧。
