1、An droid應(yīng)用程序開發(fā)實(shí)驗(yàn)報(bào)告學(xué) 號(hào):131006105學(xué)生：會(huì)會(huì)扌旨導(dǎo)教師：齊兵輝提交時(shí)間：第一章系統(tǒng)分析與設(shè)計(jì)31.1系統(tǒng)的可行性分析31.2系統(tǒng)的需求分析4第二章系統(tǒng)詳細(xì)設(shè)計(jì) 42.1 ACTIVITY的詳細(xì)設(shè)計(jì)42.2 XML文件的詳細(xì)設(shè)計(jì) 4第三章測試運(yùn)行及總結(jié)193.1界面截圖293.2運(yùn)行界面截圖303.3運(yùn)行結(jié)果截圖31目錄3.4總結(jié)35第一章系統(tǒng)分析與設(shè)計(jì)1.1系統(tǒng)的可行性分析可行性研究是為了弄清楚系統(tǒng)開發(fā)的工程是不是可以實(shí)現(xiàn)和值得進(jìn)展研究的過程，實(shí)際上是一次大大簡化系統(tǒng)分析和系統(tǒng)設(shè)計(jì)的過程，所以，進(jìn)展可執(zhí)行性的分析是非常必要的，也是很重要的，經(jīng)過最初的設(shè)計(jì)目標(biāo)和進(jìn)展的

2、實(shí)時(shí)調(diào)查 得出以下四點(diǎn)的可行性分析：1技術(shù)可行性：Eclipse + An droid ADT的技術(shù)已經(jīng)較為成熟，通過SUN公司現(xiàn)被ORCEL公司收購?fù)瞥龅目缙脚_(tái)、動(dòng)態(tài)的 JAVA語言進(jìn)展開發(fā)。2運(yùn)行可行性：該系統(tǒng)需要An droid虛擬機(jī)環(huán)境，Eclipse中安裝ADT，DDMS等Google An droid 相關(guān)插件。其運(yùn)行環(huán)境已經(jīng)相當(dāng)穩(wěn)定，它功能豐富， 包括了完備的 An droid 程序的編碼、調(diào)試、測試和發(fā)布功能，其中支持所有An droid 應(yīng)用開發(fā)相關(guān)技術(shù)，包括 SQLite，Skia，3D制作，An droid XML， 能夠很好的發(fā)布An droid的應(yīng)用程序APK包。3法

3、律可行性：因?yàn)槭亲灾鏖_發(fā)設(shè)計(jì)，所以不會(huì)構(gòu)成侵權(quán)，在法律上是可行的通過以上的可行性分析，將采用Eclipse+Android ADT + DDMS 技術(shù)，運(yùn)用JAVA語言進(jìn)展系統(tǒng)的開發(fā)。1.2系統(tǒng)的需求分析根據(jù)分析需求，這個(gè)系統(tǒng)必須實(shí)現(xiàn)以下的功能:(1) 實(shí)現(xiàn)簡單的數(shù)字計(jì)算功能。作為計(jì)算器，其核心就是加減乘除。(2) 能夠在手機(jī)里面以良好的界面。第二章系統(tǒng)詳細(xì)設(shè)計(jì)2.1 activity 的詳細(xì)設(shè)計(jì)package .example.cou nter;importan droid.os.Bu ndle;importan droid.app.Activity;importan droid.view.
