java.lang.IllegalStateException

Hi,
I have the following error:

java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread.

How can I solve that? I've just implemented the PullToRefreshView like in the sample code.

Thanks

Hi,

The first line says it all, really: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread.

You can for example use the runOnUiThread(...) method to post a runnable to the UI thread where you modify the content of the adapter. It has nothing to do with the PullToRefresh implementation by the way, it's the ListView itself.

Hi,
I modify the content on a runOnUiThread, but still having the issue.

[erikwt]

Do you call notifyDataSetChanged() on the adapter?

Yes, inside the runOnUiThread I call the adapter notifyDataSetChanged().
