notifyItemRangeRemoved

The notifyItemRangeRemoved method is a crucial part of Android's RecyclerView, a powerful and flexible view for displaying large sets of data. This method is called by an Adapter to inform the RecyclerView that a contiguous range of items has been removed from the data set.

When notifyItemRangeRemoved is invoked, it signals to the RecyclerView that it needs to update its visual representation to reflect the data change. The RecyclerView then efficiently animates the removal of the affected items from the screen. This method takes two integer arguments: a position of the first item removed and the number of items removed. For example, calling notifyItemRangeRemoved(5, 3) would indicate that three items starting from index 5 have been removed.

Using notifyItemRangeRemoved is generally more efficient than calling notifyItemRemoved individually for each removed item, especially when multiple items are deleted consecutively. This batch notification allows the RecyclerView to perform a single, optimized update operation. Proper use of this method ensures smooth and performant user interfaces when dealing with dynamic data in RecyclerViews. It is essential to ensure the positions and counts provided are accurate to prevent unexpected behavior or visual glitches.
