notifyItemRangeChanged

The notifyItemRangeChanged method is a function commonly found in adapter classes for RecyclerView in Android development. Its primary purpose is to efficiently inform the RecyclerView about changes that have occurred within a specific range of items in the underlying data set. This allows the RecyclerView to update only the affected views, rather than the entire list, leading to improved performance, especially for large datasets.

When notifyItemRangeChanged is called, it typically takes two integer arguments: a starting position and a count. The starting position indicates the index of the first item in the range that has been modified. The count specifies how many consecutive items, starting from the given position, have changed. For example, calling notifyItemRangeChanged(5, 3) would signal that items at indices 5, 6, and 7 have been updated.

The RecyclerView adapter uses this notification to rebind the views corresponding to the changed items. This means that the `onBindViewHolder` method will be called for each item within the specified range, refreshing their content with the updated data. It is crucial to call this method whenever the data in the range has been modified to ensure the UI accurately reflects the current state of the data. Using notifyItemRangeChanged is generally more performant than calling notifyDataSetChanged, which invalidates the entire dataset and forces a complete re-render of all visible items.
