How to achieve partial refresh of recyclerview in Android

In Android, you can achieve partial refresh using the notifyItemChanged() method of RecyclerView. This method is used to update the data of a specific item at a given position and redraw that item. The specific steps are as follows:

1. Obtain the position of the item to be refreshed.
2. Call the notifyItemChanged() method of RecyclerView, passing in the position of the item to be refreshed.

The sample code is as follows:

// 获取要刷新的item的位置
int position = 2; // 假设要刷新第3个item

// 调用RecyclerView的notifyItemChanged()方法，传入要刷新的item的位置
recyclerView.getAdapter().notifyItemChanged(position);

In actual development, you can update the data of a specific item according to the requirements, then call the notifyItemChanged() method to refresh that item.
