Android如何使用使用。循环视图

implementation 'androidx.recyclerview:recyclerview:1.3.0'

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

RecyclerView recyclerView = findViewById(R.id.recyclerView);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);  // 设置布局管理器
recyclerView.setLayoutManager(layoutManager);
RecyclerView.Adapter adapter = new MyAdapter(dataList);  // 创建并设置适配器，其中dataList是数据集合
recyclerView.setAdapter(adapter);

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<DataItem> dataList;  // 数据集合

    // 自定义ViewHolder，用于缓存视图
    public static class ViewHolder extends RecyclerView.ViewHolder {
        public TextView textView;

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

    // 构造方法，传入数据集合
    public MyAdapter(List<DataItem> dataList) {
        this.dataList = dataList;
    }

    // 创建ViewHolder并返回
    @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);
    }

    // 绑定数据到ViewHolder
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        DataItem dataItem = dataList.get(position);
        holder.textView.setText(dataItem.getTitle());
    }

    // 返回数据集合的大小
    @Override
    public int getItemCount() {
        return dataList.size();
    }
}
