A way to look at this which just occurred to me is:
getSelectedItem() has to do with the data backing up the spinner. This works even if the spinner stays hidden / gone the whole time, as it should, since the data backing up the spinner always exists, regardless of UI state.
getSelectedTextView() has to do with the data's presentation. If there spinner stayed hidden, there was never any presentation, and that's the value you're getting.
Makes sense? -- Kostya 21.04.2011 20:51, Keith Wiley пишет:
I agree, and I can adapt my code to use the selected item instead of the selected view...but it is worth noting that the consequence of this is that seemingly identical layouts can yield very different behavior. In this case, two layouts containing invisible items can return either a valid view or a null, which is both dangerous and somewhat arbitrary...not random of course, but slightly arbitrary. I'm just pointing that out, I'm not arguing against the optimization necessarily.
