android - Dynamically adding Views in a RecyclerView only to current item

Question

I'm dynamically adding Views to my items in a RecyclerView. These added Views should only be related to the item which they're added to, but I'm having a problem when I scroll. It seems the View is recycled and a new item is loaded, but those previously added views are still there, only now on the wrong item.

I'm assuming that it's just because the ViewHolder is being reused, so the added items show up again with a new item, when loaded.

How would one go about solving this?

This was an old question of mine. A bounty was placed on it, hence the surge of popularity and the multiple new and irrelevant answers.

As stated in both my comment to this answer and @CQM's comment below my original question, the answer is to override the onViewRecycled() method and perform any needed operations there. This method is called when a view is recycled, and any cleanup operations can be done here.

Documentation on this method can be found here.

In my case, it was a matter of deleting the invisible TextView's attached to the view. The text itself had been deleted, but the view remained. If many invisible TextView's accumulate on the view and aren't properly recycled when scrolling, the scroll will begin to lag.
