摘 要

随着我国经济建设的高速发展，人们的消费观念和方式都发生了质的飞跃，现今社会既有崇尚节俭的70后，也有“月光”且事事都要尝试的90后。国内财务软件从无到有，经过许多年的发展，已逐步走向成熟。IT行业多年的快速发展以及技术上的累计使得财富管理类应用变得多样与便捷，记账类App的诞生也更能满足用户对于财富管理的需求。时至今日，消费途径和消费方式的多元化使得人们对于记账App的期待，已经不仅仅是记录和统计这么简单。

面对人们各种收入和消费途径的繁杂多样，如何能使软件用户更加便捷的记录成为软件开发者的重中之重。现在市面上的记账APP的功能除了本身的记账以外，繁杂花哨的界面风格和过多复杂无用功能的加入，使得用户在App的使用与学习成本上花费过多的时间，丢失了原本的方便快捷。

基于以上问题，本文自主设计并实现了一款基于Android的记账App。搭建了由Android SDK、JDK、ADK等开发工具所组成的Android开发平台，UI设计为Android原生，采用Java语言独立设计并开发出的一款基于Android的记账App。数据交互使用HTTP网络协议，采用Bmob云数据库进行数据存储，便于后续的维护和开发，不同设备登录后，同一账户的数据可以进行同步，便于用户使用。该软件具备注册/登录功能、管理收支功能、数据统计分析功能，帮助用户提高记账的效率，简便记账的过程。趣味性功能的加入，可以调动用户使用的积极性，提高用户的产品体验。

Design and implementation of accounting app based on Android

Abstract

With the rapid development of China's economic construction, people's consumption ideas and ways have taken a qualitative leap. Nowadays, there are not only the Post-70s who advocate thrift, but also the post-90s who advocate "Moonlight clan" and try everything. Domestic financial software has developed from scratch, and has gradually become mature after many years of development. With the rapid development of IT industry and the accumulation of technology for many years, wealth management applications become diversified and convenient, and the birth of accounting app can meet the needs of users for wealth management. Up to now, the diversification of consumption channels and consumption modes makes people's expectation for bookkeeping app more than just record and statistics.

Faced with the complexity of people's various income and consumption channels, how to make software users more convenient to record has become the top priority of software developers. In addition to its own bookkeeping, the functions of the bookkeeping app on the market now have complicated and fancy interface style and too many complex and useless functions, which make users spend too much time on the use and learning cost of the app and lose the original convenience and efficiency.

Based on the above problems, this paper designs and implements a billing app based on Android. An android development platform composed of Android SDK, JDK, ADK and other development tools has been built. The UI is designed as Android native, and an Android based accounting app has been independently designed and developed in Java language. HTTP network protocol is used for data interaction, and bmob cloud database is used for data storage, which is convenient for subsequent maintenance and development. After different devices log in, the data of the same account can be synchronized, which is convenient for users to use. The software has the functions of registration / login, management of revenue and expenditure, data statistics and analysis, which can help users improve the efficiency of bookkeeping and simplify the process of bookkeeping. The addition of interesting functions can mobilize the user's enthusiasm and improve the user's product experience.

第一章 绪论

1.1 选题背景

生活中，经常看到很多学生因为超前消费、透支消费导致用钱紧张，借钱消费和拮据度日成了家常便饭，犯罪分子的趁虚而入也使得裸贷等多种违法犯罪行为应运而生。除了从法律上去遏制那些不法分子，养成记账理财的习惯，学会控制自己的欲望，抵制超前消费这种行为显得格外重要。
