Why RemoteViewsFactory method getViewAt work wrong but not always?

Question

Sometimes when my widget is updating I see in log that:

..

getViewAt position = 7

getViewAt position = 7 ..

And at first time RemoteViews object is placed on position 0 at second time on position 7. Why this is happening? Why it call object with id 7 but place it on position 0?

答：在ListView中，您不能设置高度wrap_context，因为如果您有10、20、100或更多元素，则视图不知道它是什么。
