Question

我在SimpleCursor适配器和Loader Manager（支持v4）的帮助下填充了gridview。在分页的帮助下从web服务器获取gridview的内容。如果我在webservice调用期间快速切换详细视图和gridview之间的视图我得到非法状态错误/ StaleDataException。

也许您忘了在resetLoader回调中添加adapter.swapcursor（null）？我遇到了相同的日志，而这个日志已经丢失，并且多次打开+关闭了listfragment ..

SimpleCursor适配器，LoaderManager IllegalState异常或StaleData异常
