第一轮铁大树洞APP开发冲刺(6)

写在前面

今天基本上睡了一天,下午起来后开始处理队友做完的登录注册模块与后面模块的联系。最后做完了“我的”模块。在写代码的过程中遇到了很多粗心的问题,也有很多底子不稳的问题。但主要还是业务逻辑没有理清。理清业务逻辑后基本写代码就一路顺畅了。到今天我负责的后台代码已经全部写完了,我算了算,大概一共2500行...其实真的写起来也感觉不到很多,主要还是业务逻辑要理清。

登录和注册就不再演示了。
直接演示我的模块:


实现逻辑

整体的实现逻辑和之前类似,书写API,然后对API中获取的数据进行处理即可:

            }
        }).start();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View rootView = inflater.inflate(R.layout.fragment_my_receive, container, false);
        mXRecyclerView = rootView.findViewById(R.id.recycler_view_my_receive);
        return rootView;
    }

}

这里只贴一点

总结

今天大部分时间都在理清业务逻辑。也再次提醒我自己要好好思考后再下手。
