android书籍 资料

在这里我介绍另一本Android的教程-Android Application Development,出版社O’Reilly 我想大家再熟悉不过了,下面是这本书的一点介绍: 概要(Overview) Android是一个为手机设计的开源平台,在这个行业里激起了强烈的热情,这部实用教程为开发Android软件的人介绍了重要的概念并提供了一些代码。本书介绍了它的开发环境,并提供了一个完整的开发例程,向读者诠释了Android的功能架构和API。读这本书,你将会: 详尽地了解Android的开发环境、架构和工具 创建一个应用程序模型,从这个基本的模型出发,逐步加入后面章节的功能内容。 了解一些典型功能的概念和架构,包括views,地图,基于GPS的服务,数据存储,2D和3D图形,媒体服务,通话服务和短信息等。 使用已有的例子代码来实现各个功能 深入研究高级课题,例如安全性,自定义视图,性能分析和国际化。 这本书是对已有的Google提供的Android文档进行了自然的完善。你是想要为手机设备开发商用软件,或者仅仅是作为个人爱好,Android Application Development这部书都都可以为你介绍应该如何设计、创建和测试你的应用程序。 作者介绍(About the Authors) Rick Rogers是一位专业的嵌入式软件工程师,他作为软件市场管理人员已经有超过30年的经验了。在过去的8年里,Rick Rogers专注于手机应用程序开发,为康柏、英特尔和Marvel半导体等公司开发手机软件,制订战略和市场计划。 John Lombardo从0.9版本开始就一直在进行Linux方面的工作。他的第一部书,Embedded Linux于2001年出版。从那时开始,他在多种不同的嵌入式设备上进行开发,包括手机和路由器等。John拥有计算机科学学士学位,并正在攻读MBA学位。 内容组织(Format of this book) 本书是面向那些有经验的编程人员,帮助他们快速地了解如何在Android环境下进行开发,本书第一章主要覆盖了一下内容:新的Android概念,Android开发环境,Android用户界面,Intents,基于定位(GPS)和地图的服务,保存数据,图像图形,通信等。在接下来的三章,2~4章中,本书为你建立了一个应用程序,并告诉你这些文件和基础的类是如何协作的。第五章让你有一个更深入的理解,并开始调试你的程序。第六章介绍Android工具包(toolkit),在第七章向你介绍如何设计和发布你的应用程序,第八章介绍了两个数据存储系统,在第九章中,你可以学会如何定位和使用地图,10~12章介绍了图形编程。第十三章将更加深入地介绍Android复杂而独特的功能,在这里讨论了应用程序如何向其他应用程序提供功能,这设计到一个程序在其他已有程序的基础上开发新功能的问题。我们别忘了Android是在手机上运行的,所以在十四、十五两章介绍如何使用电话的功能。

三级C语言上机100题

修订者 木易 (2008 年 9 月) 为解决大部分考生使用网上不同的南开100 题,造成对 各个版本的解题方法各有不同的疑惑,加上很多解题不易理解,容易产生误解,现综合本论坛会员的反聩,以及 2005年9月实际上机考试的情况,特对100题进行重新编排修订。 ******************************************************************************* ☆题目 1 请编写一个函数 jsValue(int m,int k,int xx[]),该函数的功能是:将大于整数 m且紧靠 m的 k 个素数存入数组 xx传回。 最后调用函数 writeDat()读取 10组数据,分别得出结果且把结果输出到文件 out.dat中。 部分源程序存在文件prog1.c中。 例如:若输入 17 5 则应输出:19,23,29,31,37。 请勿改动主函数 main()和写函数 writeDat()的内容。

跟我一起写Makefile

跟我一起写 Makefile 陈皓 (CSDN) pdf格式 什么是makefile?或许很多Winodws的程序员都不知道这个东西, 因为那些Windows的 IDE 都为你做了这个工作,但我觉得要作一个好的和professional的程序员,makefile 还是要懂。 这就好像现在有这么多的 HTML 的编辑器,但如果你想成为一个专业人士,你还是要了解 HTML 的标识的含义。特别在Unix下的软件编译,你就不能不自己写makefile了,会不会写 makefile,从一个侧面说明了一个人是否具备完成大型工程的能力。
