Android RecyclerView : notifyDataSetChanged() IllegalStateException

Question

I\'m trying to update the items of a recycleview using notifyDataSetChanged().

This is my onBindViewHolder() method in the recycleview adapter.

I ran into this exact issue! After Moonsoo's answer didn't really float my boat, I messed around a bit and found a solution that worked for me.

First, here's some of my code:

    @Override
    public void onBindViewHolder(ViewHolder holder, final int position) {

    final Event event = mDataset.get(position);

    //
    //  .......
    //

    holder.mSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            event.setActive(isChecked);
            try {
                notifyItemChanged(position);
            } catch (Exception e) {
                Log.e("onCheckChanged", e.getMessage());
            }
        }
    });

You'll notice I'm specifically notifying the adapter for the position I'm changing, instead of the entire dataset like you're doing. That being said, although I can't guarantee this will work for you, I resolved the problem by wrapping my notifyItemChanged() call in a try/catch block. This simply caught the exception, but still allowed my adapter to register the state change and update the display!

Hope this helps someone!

EDIT: I'll admit, this probably is not the proper/mature way of handle the issue, but since it doesn't appear to be causing any problems by leaving the exception unhandled, I thought I'd share in case it was good enough for someone else.
