How to turn list scrolling off when calling onContentChanged in Android ListActivity?

Question

Hello all,

I got a ListActivity.

I update the activity using onContentChanged() API.

My problem is that each time I call the above API the list scrolls to the top. Is there any easy way to turn this "feature" off?

Thanks.

Activity#onContentChanged is not for 'updating' the data for the activity. It is called when the content view of the activity changes, i.e., when Activity#setContentView is called. The ListActivity will reinitialize it's content view when it receives onContentChanged.

The answer is, you're doing it wrong, don't use onContentChanged the way you are using it. That is why you are seeing this unexpected behavior. Use another method to update the ListView, most probably by calling notifyDataSetChanged from your Adapter.
