2、、 1系統(tǒng)得可行性分析可行性研究就是為了弄清楚系統(tǒng)開發(fā)得項目就是不就是可以實現(xiàn)與值得進 行研究得過程，實際上就是一次大大簡化系統(tǒng)分析與系統(tǒng)設計得過程，所以，進行可執(zhí)行性得分析就是非常必要得， 也就是很重要得，經(jīng)過最初得設計目標與進 行得實時調(diào)查得出以下四點得可行性分析：(1)技術(shù)可行性：Eclipse + Andro i d ADT得技術(shù)已經(jīng)較為成熟，通 過S UN公司(現(xiàn)被O RCEL公司收購)推出得跨平臺、動態(tài)得 JAVA語言進行 開發(fā)。(2)運行可行性：該系統(tǒng)需要Andro i d虛擬機環(huán)境，Ec l i p se中安裝AD T, DDMS等Google An droid相關(guān)插件.其運行

3、環(huán)境已經(jīng)相當穩(wěn)定，它功能豐富, 包括了完備得A ndroid程序得編碼、調(diào)試、測試與發(fā)布功能，其中支持所有An droid應用開發(fā)相關(guān)技術(shù)，包括SQLit e ,Skia ,3D制作,A n droid XML,能夠很好 得發(fā)布A ndro id得應用程序A PK包。( 3) 法律可行性：因為就是自主開發(fā)設計,所以不會構(gòu)成侵權(quán),在法律上就是可行得。通過以上得可行性分析，將采用Ecl i pse+ A n dro i d ADT + D DMS技 術(shù)，運用JAV A語言進行系統(tǒng)得開發(fā)。1、2系統(tǒng)得需求分析根據(jù)分析需求,這個系統(tǒng)必須實現(xiàn)以下得功能(1)實現(xiàn)簡單得數(shù)字計算功能.作為計算器，其核心就就

4、是加減乘除。( 2) 能夠在手機里面以良好得界面。第二章系統(tǒng)詳細設計2、1 a cti v i t y得詳細設計p a c k a ge、e xampl e、cou n t er ；i m port a n dr o id、os、 B u nd 1 e;import androi d、a pp、Ac t ivity ;i mp o r t a n dro i d、 vi e w、Men u ;import android、vi ew、V i e w；import and r o i d、 vie w、View、OnClic k L iste ne r ;i m p o rt and r oid
