【移動(dòng)應(yīng)用開(kāi)發(fā)技術(shù)】Android如何實(shí)現(xiàn)機(jī)房座位預(yù)約系統(tǒng)

這篇文章主要介紹Android如何實(shí)現(xiàn)機(jī)房座位預(yù)約系統(tǒng)，文中介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們一定要看完！具體內(nèi)容如下

這周要去武漢開(kāi)會(huì)，下周項(xiàng)目就得用上，所以，比較緊。加上導(dǎo)師不懂Android開(kāi)發(fā)，只要開(kāi)會(huì)就改需求，/(ㄒoㄒ)/~~反正他說(shuō)先讓學(xué)校用著，移動(dòng)端和服務(wù)器的開(kāi)發(fā)就給了兩周時(shí)間。所以功能實(shí)現(xiàn)的比較簡(jiǎn)單，但代碼做的比較容易擴(kuò)展，都留了接口，后面更新起來(lái)也好做一些。通過(guò)這個(gè)工程，對(duì)Struts2的攔截器有了一些新體會(huì)。隨著項(xiàng)目變大代碼量變多，自然而然就會(huì)想起用一些設(shè)計(jì)模式了。不然代碼根本沒(méi)辦法看。整體是4個(gè)fragment，每個(gè)fragment里都有課程表的布局，課程可以從服務(wù)器傳過(guò)來(lái)動(dòng)態(tài)生成。其實(shí)很多都可以復(fù)用的布局，為了代碼結(jié)構(gòu)清晰，都分開(kāi)寫(xiě)了。不然需要加控制器，調(diào)試起來(lái)心累。寫(xiě)的不好，還請(qǐng)大家多指教。做的還不完善，弄完以后再傳上來(lái)。Application里對(duì)數(shù)據(jù)進(jìn)行持久化，這么做發(fā)現(xiàn)程序變得比較容易控制了。Applicationpackage
