2、是一次大大簡化系統(tǒng)分析和系統(tǒng)設(shè)計的過程，所以，進(jìn)行可執(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)計目標(biāo)和進(jìn)行的實時調(diào)查 得出以下四點的可行性分析：（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）推出的跨平臺、動態(tài)的 JAVA 語言進(jìn)行開發(fā)。（2） 運行可行性：該系統(tǒng)需要 An droid 虛擬機環(huán)境，Eclipse 中安裝 ADT，DDMS 等 Google An droid 相關(guān)插件。其運行環(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

3、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） 法律可行性：因為是自主開發(fā)設(shè)計，所以不會構(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)， 運用 JAVA語言進(jìn)行系統(tǒng)的開發(fā)。1.2 系統(tǒng)的需求分析根據(jù)分析需求，這個系統(tǒng)必須實現(xiàn)以下的功能：（1）實現(xiàn)簡單的數(shù)字計算功能。作為計算器，其核心就是加減乘除。（2）能夠在手機里面以良好的界面。第二章系統(tǒng)詳細(xì)設(shè)計2.1 activity 的詳細(xì)設(shè)計p
