如何在recyclerview中动态添加内容

// 1. 创建RecyclerView
RecyclerView recyclerView = findViewById(R.id.recyclerView);

// 2. 创建数据源
List<String> dataList = new ArrayList<>();

// 3. 创建适配器
MyAdapter adapter = new MyAdapter(dataList);

// 4. 创建ViewHolder
class MyViewHolder extends RecyclerView.ViewHolder {
    TextView textView;

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

// 5. 绑定数据
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    String data = dataList.get(position);
    holder.textView.setText(data);
}

// 6. 设置布局管理器
recyclerView.setLayoutManager(new LinearLayoutManager(this));

// 7. 设置适配器
recyclerView.setAdapter(adapter);

// 8. 添加新内容
dataList.add("New Content");
adapter.notifyItemInserted(dataList.size() - 1);
