p层

                    @Override

                         shopView.getShop(shopCartBean.getData());
                    }
                });
    }
}

v层

public interface ShopCartView {
    void getShop(List dataBeans);
}

再需要用到的地方调用p层

ShopCartPresenterImpl presenter = new ShopCartPresenterImpl(this);
presenter.getShop("71");
