 解决方案：http://stackoverflow.com/questions/2596547/arrayindexoutofboundsexception-with-custom-android-adapter-for-multiple-views-in

The item view type you are returning from

getItemViewType() is >= getViewTypeCount().

也就是你的viewType的type类型必须从0开始，{0，1，2，3...}这样的.

typecount大于最后一个类型的type即可.

这样就解决了，ListView多种viewType滑动到底，上滑崩溃的现象.
