更改recyclerview的layoutmanager时更改视图（xml）

Question

我是android的新手，我想在更改LayoutManger时更改用于Recylcer视图的xml文件

例如（我为学习做一个小项目，是一个pokedex）

什么时候需要线性布局？
 

但是当我将recyclerView的布局更改为网格布局时，我想使用此布局

这是我的适配器：

public class MyDataAdapter extends RecyclerView.Adapter<MyDataAdapter.PokemonViewHolder> {

private List<PokemonViewModel> pokemonViewModelList;
private PokemonActionInterface pokemonActionInterface;
private Boolean viewchoice = true;

public Boolean getViewchoice() {
    return viewchoice;
}

public void setViewchoice(Boolean viewchoice) {
    this.viewchoice = viewchoice;
}



// Provide a suitable constructor (depends on the kind of dataset)
public MyDataAdapter(List<PokemonViewModel> dataset,PokemonActionInterface pokemonActionInterface) {
    pokemonViewModelList = dataset;
    this.pokemonActionInterface = pokemonActionInterface;
}

/*public void bindViewModels(List<PokemonViewModel> pokemonViewModelList) {
    this.pokemonViewModelList.clear();
    this.pokemonViewModelList.addAll(pokemonViewModelList);
    notifyDataSetChanged();
}*/

// Create new views (invoked by the layout manager)
@Override
public MyDataAdapter.PokemonViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    // create a new view
    View v = LayoutInflater.from(parent.getContext())
            .inflate(getView(), parent, false);
    PokemonViewHolder pokemonViewHolder = new PokemonViewHolder(v);
    return pokemonViewHolder;
}

public int getView(){
    if (this.getViewchoice()) {
        return R.layout.item_recyclerview_grid;
    }
    return R.layout.item_recyclerview;
}



// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(final PokemonViewHolder holder, int position) {
    String idString = String.valueOf(pokemonViewModelList.get(position).getId());
    holder.idTextView.setText(idString);
    holder.nameTextView.setText(pokemonViewModelList.get(position).getName());
    holder.iconImageView.setImageResource(R.drawable.rayquaza);
    RequestOptions options = new RequestOptions()
            .centerCrop()
            .placeholder(R.mipmap.ic_launcher_round)
            .error(R.mipmap.ic_launcher_round);
    holder.pokemonButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            pokemonActionInterface.onPokemonClicked(holder.nameTextView.getText().toString());
        }
    });
    //holder.setupListeners();
}

public List<PokemonViewModel> getPokemonViewModelList() {
    return pokemonViewModelList;
}

// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
    return pokemonViewModelList.size();
}


public static class PokemonViewHolder extends RecyclerView.ViewHolder {
    private TextView nameTextView;
    private TextView idTextView;
    private ImageView iconImageView;
    private ImageButton pokemonButton;
    private View v;
    //private PokemonActionInterface pokemonActionInterface;


    public PokemonViewHolder(View v) {
        super(v);
        this.v = v;
        nameTextView = v.findViewById(R.id.namePokemon_textview);
        idTextView = v.findViewById(R.id.idPokemon_textview);
        iconImageView = v.findViewById(R.id.icon_imageview);
        pokemonButton = v.findViewById(R.id.pokemon_button);
        //setupListeners();

    }}}

抱歉，如果我不清楚，我是初学者...
你有主意吗？
我用boolean（viewchoice）尝试了一些东西，但这是行不通的...

谢谢
