问题 I'm trying to tackle a problem that seemingly many Android developers have, which is how to intersperse lists with non-list data, in one big scrollable pane. The model I have in mind is the screen for an individual app in the Market. You have a big description, a list of a few lazily loaded comments, and then some individual items that do different things, like visit the developer's web page, call them, etc. And then in between them all, are nice section headers.

问题 I have a layout like this (abstracted): Scrollview - fill_parent LinearLayout - wrap_content ImageView 1 - wrap_content ImageView 2 - ... ImageView 3 ... In the course of user interaction some images are replaced by larger or smaller ones, shortening or lenghtening the area to be scrolled. And that is the problem.

问题 I am using for C# in Xamarin to create an android app. I have created an extension of the scrollview.

问题 I am filling a listView, then I wanted to do something fancy. I tried to add an OverScroll Header to the list, the effect I expected is that if I overscroll the list, a drawable will show up on top of the list, so the overscroll header looks like a hidden header for the list.
