MVP实现展示信息

model类

public class HomeModel implements IHomeModel{


    @Override
    public void getData(String url, final ModelInterface modelInterface) {
        OkHttp.okHttpGet(url, new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                modelInterface.loadSuccess(response.body().string());
            }
        });
    }
}

model接口

public interface IHomeModel {
    //获取数据
    void getData(String url,ModelInterface modelInterface);
    //定义接口
    interface ModelInterface{
        void loadSuccess(String data);
        void loadFailed();
    }
}

presenter类

public class HomePresenter implements IHomePresenter{

   HomeFragment homeFragment;
    private final HomeModel homeModel;

    public HomePresenter(HomeFragment homeFragment) {
        this.homeFragment = homeFragment;
        homeModel = new HomeModel();
    }

    @Override
    public void getPresenterData() {
        homeModel.getData(Api.SHOPLIST, new IHomeModel.ModelInterface() {
            @Override
            public void loadSuccess(String data) {
                homeFragment.getViewData(data);
            }

            @Override
            public void loadFailed() {

            }
        });
        homeModel.getData(Api.BUNNER, new IHomeModel.ModelInterface() {
            @Override
            public void loadSuccess(String data) {
                homeFragment.getBannerData(data);
            }

            @Override
            public void loadFailed() {

            }
        });
    }

}

presenter接口

public interface IHomePresenter {
    //获取model
    void getPresenterData();
}

view接口

public interface IHomeView {
    void getViewData(String mViewData);
    void getBannerData(String banner);
}

在fragment中展示

public class HomeFragment extends Fragment implements IHomeView {

    private XBanner xbanner;

    private GridView grid_view_rxxp;
    private ListView list_view_mlss;
    private GridView grid_view_pzsh;

    @Nullable
    @Override

        //初始化presenter
        HomePresenter homePresenter = new HomePresenter(this);
        homePresenter.getPresenterData();
        return view;
    }

    @Override

                }
                ........
            }
        });


    }

    @Override

        Gson gson = new Gson();
        MyBanner myBanner = gson.fromJson(banner, MyBanner.class);
        final List<MyBanner.ResultBean> result = myBanner.getResult();
        getActivity().runOnUiThread(new Runnable() {
            @Override

                xbanner.setData(result,null);
                xbanner.setmAdapter(new XBanner.XBannerAdapter() {
                    @Override

                    }
                });
                xbanner.setPageTransformer(Transformer.Default);
                xbanner.setPageChangeDuration(500);
            }
        });
    }

    @Override
    public void onResume() {
        super.onResume();
        xbanner.startAutoPlay();
    }

    @Override
    public void onStop() {
