添加到购物车的model层

/**
 * 添加购物车的model层
 *
 * */
public class AddShopCarModel  {
    public void receive(String source, String uid, String pid, final IAddShopCarModel iAddShopCarModel) {
        HashMap<String, String> hashMap = new HashMap<>();
        hashMap.put("uid",uid);
        hashMap.put("pid",pid);
       OkHttpUtils.getInstance().doPost("http://120.27.23.105/product/addCart", hashMap, new CallBack() {
            @Override
            public void onSuccess(String str) {
                if(str!=null){

                    AddShopCarBean addShopCarBean = GsonUtils.getInstance().fromJson(str, AddShopCarBean.class);
                    if(addShopCarBean!=null){
                        String msg = addShopCarBean.getMsg();
                        iAddShopCarModel.onSuccess(msg);
                    }
                }
            }

            @Override
            public void onFailed(String message) {
                iAddShopCarModel.onFailed();
            }
        });
    }
}

添加购物车presenter层

public class AddShopCarPresenter implements IAddShopCarModel {

    private AddShopCarModel addShopCarModel;
    private IAddShopCarPresenter iAddShopCarPresenter;

    public AddShopCarPresenter(IAddShopCarPresenter iAddShopCarPresenter) {
        this.iAddShopCarPresenter = iAddShopCarPresenter;
        addShopCarModel = new AddShopCarModel();
    }

    public void receive(String source, String uid, String pid) {
        addShopCarModel.receive(source,uid,pid,this);
    }

    @Override
    public void onSuccess(String msg) {
        iAddShopCarPresenter.onSuccess(msg);
    }

    @Override
    public void onFailed() {
        iAddShopCarPresenter.onFailed();
    }
}

model层的接口

public interface IAddShopCarModel {

    void onSuccess(String msg);

    void onFailed();

}

presenter层的接口

public interface IAddShopCarPresenter {

    void onSuccess(String msg);

    void onFailed();

}
