smoothScrollToPosition after notifyDataSetChanged not working in android

Question

I\'ve got a custom Adapter for a ListView setup and working ok. On a button click something is changed in the underlying data, so a notifyDataSetChanged is required to refre

Answer 1

I've tried the dmon's example code and I see it not always working.

Actually I've found another approach to perform scrolling:

adapter.notifyDataSetChanged();
channelsListView.setSelection(scrollPos); // it works without smoothScrollToPositionFromTop(..) or smoothScrollToPosition() methods call.

I found the main idea to use above method after this answer reading: https://stackoverflow.com/a/20997828/2133585

Answer 2

Use the post() method to wait for the list to finish updating after you call notifyDataSetChanged():

adapter.notifyDataSetChanged();
list.post( new Runnable() {
    @Override
    public void run() {
    //call smooth scroll
    }
  });
