Question

我正在实施MVP架构，代码工作正常，如果我可以进行改进，或者在我没有正确遵循模式的任何领域，我想要你的建议。

使用RecyclerViews列出片段中的游戏是一个简单的应用程序。

FGames - 显示游戏列表的片段

public class FGames extends Fragment implements GamesView {

    @BindView(R.id.rv_games)
    RecyclerView rvGames;
    private GamesAdapter gamesAdapter;
    private GamesPresenterImpl presenter;
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.games_layout, container, false);
        ButterKnife.bind(this, view);
        presenter = new GamesPresenterImpl(this);
        return view;
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        presenter.initUi();
    }

    @Override
    public void initRecyclerView(List<GameEntity> gameEntities) {
        gamesAdapter = new GamesAdapter(getActivity(), gameEntities);
        rvGames.setAdapter(gamesAdapter);
        rvGames.setLayoutManager(new LinearLayoutManager(getActivity()));
    }
}

界面 - GamesView

  public interface GamesView {

        /**
         * Initialise the recycler view to list Games data
         * @param gameEntities
         */
        void initRecyclerView(List<GameEntity> gameEntities);
    }

GamesPresenterImpl - 演示者实现

    public class GamesPresenterImpl implements GamesPresenter {

    GamesView gamesView;

    public GamesPresenterImpl(GamesView gamesView) {
        this.gamesView = gamesView;
    }

    @Override
    public void initUi() {
        gamesView.initRecyclerView(getGamesData());
    }

    public List<GameEntity> getGamesData() {
        List<GameEntity> gameEntities = new ArrayList<>();
        int counter = 0;
        for(int i = 0; i<10; i++){
            GameEntity gameEntity = new GameEntity();
            counter ++;
            gameEntity.setName("Test name " + counter);
            gameEntity.setJackpot(100000055);
            gameEntities.add(gameEntity);
        }
        return gameEntities;
    }
}

界面 - GamesPresenter

public interface GamesPresenter {
    void initUi();
}

您可以拥有第3层，您可以在其中添加所有数据获取（API /数据库）逻辑。请参阅http://www.vogella.com/tutorials/AndroidArchitecture/article.html

因此，您的数据填充部分将移至第3层

for(int i = 0; i<10; i++){
  GameEntity gameEntity = new GameEntity();
    counter ++;
            gameEntity.setName("Test name " + counter);
            gameEntity.setJackpot(100000055);
            gameEntities.add(gameEntity);
}
