基于安卓平臺(tái)的程序開(kāi)發(fā)楊婷

1、安卓平臺(tái)的程序開(kāi)發(fā)學(xué)校： 班級(jí)： 姓名： 學(xué)號(hào)： 一.實(shí)訓(xùn)技術(shù)簡(jiǎn)介Android應(yīng)用程序是在JAVA下開(kāi)發(fā)的。Android自身不是一個(gè)語(yǔ)言，但是是一個(gè)運(yùn)行應(yīng)用程序的環(huán)境。 1.eclipse Eclipse是一個(gè)開(kāi)放源代碼的、基于java的可擴(kuò)展開(kāi)發(fā)平臺(tái)，就其本身而言，它只是一個(gè)框架和服務(wù)，用于通過(guò)插件組件構(gòu)建開(kāi)發(fā)環(huán)境。eclipse附帶了一個(gè)標(biāo)準(zhǔn)的插件集，包括java開(kāi)發(fā)工具。一旦Eclipse安裝開(kāi)始，你會(huì)被提醒來(lái)創(chuàng)建一個(gè)缺省的工作空間，或者文件夾。和其他大多數(shù)開(kāi)發(fā)環(huán)境一樣，項(xiàng)目被創(chuàng)建，并且保存到這個(gè)工作空間內(nèi)。2.JDKJDK是一個(gè)寫java的applet和應(yīng)用程序的程序開(kāi)發(fā)環(huán)境。它由

2、一個(gè)處于操作系統(tǒng)層之上的運(yùn)行環(huán)境還有開(kāi)發(fā)者編譯，調(diào)試和運(yùn)行用java語(yǔ)言寫的applet和應(yīng)用程序所需的工具組成。JDK包含的基本組件包括：Javac-編譯器，將源代碼轉(zhuǎn)成字節(jié)碼Jar-打包工具，將相關(guān)的類文件打包成一個(gè)文件Javadoc-文檔生成器，從源碼注釋中提取文檔Jdb-debugger，查錯(cuò)工具JDK中還包括各種例子程序，用以展示java API中的各部分。3.android-sdkSDK：Android SDK下載后會(huì)是一個(gè)簡(jiǎn)單的ZIP文件壓縮包。Android SDK的主體是一些文件，連續(xù)性的文檔，可編程的API，工具，例子和其它。AndroidSDK和其它的SDK相比沒(méi)有任何的

3、不同，它包含了所有的創(chuàng)建運(yùn)行在特有的Android平臺(tái)上應(yīng)用程序所需的Java代碼庫(kù)。SDK還包括幫助文件，文檔和Android模擬器，大量的開(kāi)發(fā)和調(diào)試工具。被軟件開(kāi)發(fā)工程師用于為特定的軟件包、軟件框架、硬件平臺(tái)、操作系統(tǒng)等建立應(yīng)用軟件的開(kāi)發(fā)工具的集合。Android SDK指的既是android專屬的軟件開(kāi)發(fā)工具包。二實(shí)訓(xùn)項(xiàng)目簡(jiǎn)介1.編寫電話應(yīng)用 2.編寫短信應(yīng)用 3.編寫音樂(lè)播放器應(yīng)用 4.編寫紙牌游戲 5.編寫推箱子游戲 6.編寫公交查詢應(yīng)用三實(shí)訓(xùn)項(xiàng)目具體說(shuō)明（包括項(xiàng)目實(shí)現(xiàn)步驟和項(xiàng)目截圖，可以包括部分核心代碼） 1.編寫電話應(yīng)用t_app;import android.app.Activ
