Question

Hello I would like to implement pull to refresh in my Android App. But there are just Implimentations for ListViews. I would like to refresh TextViews because the Text in these TextViews is parsd from an XML(online) so whenever I change the XML and you would pull to refresh, the TextViews would be updated. Is it possible to impliment that. Are there similar projects or gits?

Thanks!

Edit:
So basically I just want the pull to refresh animation.

I would definitely take a look at Chris Banes’ implementation of pull-to-refresh. His code does not only include this interaction style for ListView, but also GridView and WebView.

Especially the latter will be of interest in your case, since it’s an example implementation of pull-to-refresh for a view that does not use an adapter for its content. If you look at the source code, you’ll see that every concrete pull-to-refreh view in Banes’ project extends from a generic PullToRefreshBase, which contains most of the logic for animation and refreshing. The benefit of having that base class is that doing the same thing for any other type of view, e.g. a TextView, should be pretty straightforward.

The only drawback of this approach is that the implementation is a wrapper for other views, meaning you’ll have write a couple of extra lines to get the actual view. So it’s not a full drop-in replacement. However, its functionality and features far exceed that little inconvenience. 🙂
