更新RecyclerView中的项目

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> mData;

    public MyAdapter(List<String> data) {
        this.mData = data;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.textView.setText(mData.get(position));
    }

    @Override
    public int getItemCount() {
        return mData.size();
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public TextView textView;

        public ViewHolder(View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.textView);
        }
    }

    // 更新数据的方法
    public void updateData(List<String> newData) {
        mData.clear();
        mData.addAll(newData);
        notifyDataSetChanged(); // 通知适配器数据集已更改
    }
}

// 假设我们有一个新的数据列表newData
List<String> newData = fetchNewData();
myAdapter.updateData(newData); // 这将更新数据并刷新RecyclerView
