How to Achieve Partial Data Refresh in RecyclerView

There are several ways to achieve partial data refresh in RecyclerView.

1. Update the item at the specified position.

// 在Adapter中的某个方法中调用
public void updateItem(int position, Data newData) {
    dataList.set(position, newData);
    notifyItemChanged(position);
}

1. Update a specific range of items starting from a certain position.

// 在Adapter中的某个方法中调用
public void updateRange(int startPosition, int itemCount, List<Data> newDataList) {
    for (int i = 0; i < itemCount; i++) {
        dataList.set(startPosition + i, newDataList.get(i));
    }
    notifyItemRangeChanged(startPosition, itemCount);
}

1. announce that an item has been inserted at a specific position

// 在Adapter中的某个方法中调用
public void insertItem(int position, Data newData) {
    dataList.add(position, newData);
    notifyItemInserted(position);
}

1. Inform that an item has been removed at the specified position.

// 在Adapter中的某个方法中调用
public void removeItem(int position) {
    dataList.remove(position);
    notifyItemRemoved(position);
}

By using the above method, it is possible to achieve partial data refresh for RecyclerView, improving performance and user experience.
