基于android的手机通讯录的设计与实现大学本科毕业论文

基于Android的天气预报查询系统的实现摘要：随着智能手机一步步走进人们的生活，它将成为人们获取信息的主要设备，相关应用越来越广泛，并在人们的日常生活中扮演着越来越重要的角色。因此，关键应用程序的开发成为影响移动智能终端普及的重要因素，设计并开发实用、方便的应用程序具有重要的意义和良好的市场前景。Android作为当前最流行的操作平台，自然也存在着大量的应用服务需求。

Android是基于Linux平台完全开源的手机操作系统，同时开发语言为Java，因此我选择了以Android为平台的手机天气预报系统来作为我的毕业设计，目的是帮助用户随时随地查询天气信息及天气变化情况，让生活更加舒适方便。本文详细讲述了Android平台下天气软件的界面设计及界面的实现、控件的使用、界面的布局等内容，结合中国气象网的天气数据，将准确的天气情况以友好的方式呈现给用户，使用户可以更加赏心悦目地体验本软件的服务。

Abstract

With the development of intelligent mobile phone step by step into people's lives, it will become the main device to obtain information, related to more widely, and plays a more and more important role in people's daily life. Therefore, the development of critical applications has become an important factor affecting the popularization of mobile intelligent terminal, application design and development of practical, convenient has important significance and good market prospects. Android as the most popular operating platform, natural also exist in application service needs of a large number of.

Android is a mobile phone operating system Linux platform based on open source, at the same time, the development of language Java, so I chose the platform of mobile phone weather system with Android as my graduation design, the purpose is to help the user whenever and wherever possible query weather information and weather condition, make life more comfortable and convenient. This paper describes the layout of content, interface design and interface control weather software under the Android platform use, interface, combined with the weather data of China Meteorological Network, will be accurate weather conditions in a friendly way is presented to the user, the user can be more pleasant experience of the software service.
