滚动游标支持的列表视图时发生崩溃

Question

就像标题所说，我有一个使用cursoradapter填充的listview。我可以为前50个元素滚动列表，但是如果我尝试进一步滚动，它会崩溃，并且它总是在同一点上崩溃。我包含了堆栈跟踪，但它对我来说并不是非常有用：所有的调用都是在android框架内完成的，所以即使我知道问题最终是封闭的数据库，但我不知道哪个部分我的代码是问题所在。在同一个应用程序中，我有其他基于游标的列表视图，不会造成任何问题。我没有任何其他的原因。

你已经关闭了你的数据库和SQLiteCursor需要填补其窗口，而滚动的ListView，看到这里https://groups.google.com/forum/#!msg/android-developers/NwDRpHUXt0U/jIam4Q8-cqQJ上时，应关闭数据库，得到的答复是：没有必要这么做
