"基于Android的计算器功能实现研究"

The rapid development of mobile communication technology and network technology has led to significant changes in mobile phone systems, from simple non-smartphones that only provide basic calling functions to the sophisticated smartphones today that offer a wide range of services such as internet browsing, messaging, email communication, video calling, and entertainment features. Google led the establishment of the OMS Alliance, which brought together many powerful software and hardware manufacturers to develop the Android platform for mobile phone systems. As a newborn platform of the era, Android presents vast development prospects with its unique advantages. This paper focuses on the development of a calculator application based on the Android platform. Utilizing the object-oriented programming language of Eclipse as the development tool, the paper designs and implements a calculator application for Android. The paper first introduces the Android development platform and environment, as well as essential components of an Android project. Subsequently, it analyzes and designs the calculator system and program, followed by the systematic implementation of the calculator application. The system is rigorously validated to ensure its functionality and accuracy. Finally, the paper concludes with a summary of the work done. Keywords: mobile phone, Android, user interface, calculator
