notifyItemChanged

NotifyItemChanged is a method in Android's RecyclerView that is used to notify a specific item in a list about data changes. This allows the RecyclerView to update the displayed data, which may have changed due to an update, addition, or removal of an item in the corresponding dataset.

The method takes two parameters: the old and new data for the item. The old data is passed as a bundle, and the new data is passed as a Parcelable object. The RecyclerView then uses this information to update the item's view, ensuring that the user sees the correct and up-to-date information.

NotifyItemChanged is most commonly used in situations where an existing item in the list needs to be updated with new data. For example, if an item in a list has been modified, either by removing or replacing data, and the user needs to see the updated item, NotifyItemChanged can be used to inform the RecyclerView about the change.

It's worth noting that calling NotifyItemChanged without passing any data to it will not prompt the RecyclerView to draw the item, and will likely cause confusion for users. Also, if you are only adding the new data, you can use NotifyItemInserted to notify the RecyclerView that an item has been inserted at a given position.

The method is a key part of the RecyclerView's data management and is an essential tool for developers when managing the lifecycle of items in a RecyclerView.
