0. 添加依赖

// 两个版本保持一致
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'

1. 设置布局

    <view class="android.support.v7.app.AlertController$RecycleListView"
        android:id="@+id/rcv_item"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

2. 创建适配器类 -以 TrainListAdapter 为例

public class TrainListAdapter extends RecyclerView.Adapter<TrainListAdapter.ViewHolder> {
    //此处可创建构造函数传数据进来
    @NonNull
    @Override
    public TrainListAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        //recycleview子项布局
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false);
        final TrainListAdapter.ViewHolder holder = new TrainListAdapter.ViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(@NonNull TrainListAdapter.ViewHolder holder, int position)         
    {
        
    }

    @Override
    public int getItemCount() {
        return 0;
    }

    //自定义类
    public class ViewHolder extends RecyclerView.ViewHolder {
        public ViewHolder(View itemView) {
            super(itemView);
        }
    }
}

3. 初始化 Recycleview , LayoutManager， TrainListAdapter

    private RecyclerView train_list_rcv;
    private LinearLayoutManager layoutManager;
    private TrainListAdapter adapter;

4. Activity 中设置

        adapter = new TrainListAdapter();
        layoutManager = new LinearLayoutManager(this); 
        layoutManager.setOrientation(LinearLayoutManager.VERTICAL); //布局管理器
        train_list_rcv.setLayoutManager(layoutManager); //设置布局管理器
        train_list_rcv.setAdapter(adapter); //设置适配器

成功绑定。
