基于Android平臺(tái)的菜譜實(shí)現(xiàn)[研究分析]

1、基于Android平臺(tái)的菜譜實(shí)現(xiàn)1需求分析隨著手機(jī)的廣泛普及，無(wú)線技術(shù)的突飛猛進(jìn)，移動(dòng)生活、移動(dòng)辦公逐漸由概念轉(zhuǎn)變?yōu)楝F(xiàn)實(shí)，對(duì)于傳統(tǒng)的餐飲業(yè)也產(chǎn)生了潛移默化的影響。目前，大多數(shù)餐廳仍然以傳統(tǒng)的紙質(zhì)菜單為主。但是,這種點(diǎn)菜方式存在諸多弊端：從消費(fèi)者角度來(lái)講，菜譜不能及時(shí)更新，導(dǎo)致菜譜信息陳舊，點(diǎn)菜時(shí)經(jīng)常出現(xiàn)某菜品已下架等情況。用戶需求：從餐廳老板來(lái)說(shuō)，及時(shí)更新紙質(zhì)的菜譜，無(wú)疑會(huì)增加餐廳的額外支出。為了改善傳統(tǒng)紙質(zhì)菜譜的弊端，將菜譜應(yīng)用于手機(jī)客戶端，為消費(fèi)者帶來(lái)更為便利的客戶體驗(yàn)。而實(shí)時(shí)的菜品更新，不僅解決了紙質(zhì)菜譜短時(shí)間內(nèi)就出現(xiàn)臟、亂、差的問(wèn)題，實(shí)現(xiàn)餐廳無(wú)紙化操作，而且潛在的提升了飯店的形象。功能

2、需求：用戶可以進(jìn)入菜單界面選擇菜品分類，進(jìn)入相應(yīng)的分類內(nèi)，查看該分類中的菜品信息，并對(duì)菜品的等級(jí)程度進(jìn)行評(píng)價(jià)，查詢某特定菜品，也可添加新菜品，刪除菜品等。2功能實(shí)現(xiàn)本APP基于自身的需求，同時(shí)對(duì)西北大學(xué)周圍眾多餐廳現(xiàn)狀的合理分析，結(jié)合實(shí)際，設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)基于移動(dòng)手機(jī)平臺(tái)的智能菜譜顯示，該系統(tǒng)的設(shè)計(jì)基于Android智能操作系統(tǒng)，簡(jiǎn)單的SQLite數(shù)據(jù)庫(kù)，實(shí)現(xiàn)了對(duì)菜品的增、刪、查、改各個(gè)功能。消費(fèi)者可以添加要點(diǎn)的菜品，在餐后可以對(duì)菜品的口味及好感程度進(jìn)行具體化的評(píng)價(jià)，這樣是對(duì)餐廳工作人員的一個(gè)回饋，同時(shí)也可以為其他消費(fèi)者就餐提供建議。2.1主界面1、實(shí)現(xiàn)了對(duì)菜品的具體分類。如圖2-1 圖2-1

3、單擊所選擇的菜品分類，出現(xiàn)菜品的鏡像顯示，為消費(fèi)者提供更為直觀的視覺(jué)效果，有助于消費(fèi)者做出選擇。如圖2-2圖2-22、是進(jìn)入菜品顯示的入口，同時(shí)也顯示了該軟件的使用方法如圖2-3： 圖2-32.2菜譜顯示界面1、該類菜品中所有菜品的具體展示，菜品名稱、菜品分類、菜品描述、菜品編號(hào)、以及菜品的星級(jí)評(píng)價(jià)，單選或多選菜品。如圖2-4： 圖2-42、搜索菜品菜譜顯示界面會(huì)顯示該分類下的所有菜品，當(dāng)需要直接看到某單個(gè)菜品的具體消息時(shí)，可以通過(guò)搜索框，進(jìn)行菜名的特定篩選。如圖2-5圖2-53、對(duì)菜品進(jìn)行添加4、刪除菜品當(dāng)菜品長(zhǎng)時(shí)間被消費(fèi)者冷落，或者有不想再推出的菜品時(shí)，進(jìn)行及時(shí)的刪除。為消費(fèi)者提供實(shí)時(shí)的消

4、息。如圖2-6： 圖2-62.3菜品添加界面當(dāng)有新的菜品推出時(shí)，進(jìn)行及時(shí)的添加，為消費(fèi)者提供更多選擇。軟件對(duì)菜品的分類給與明確的選擇，給用戶提供便利。如圖2-7： 圖2-73編碼3.1鏡像顯示public class MyMirrorGalleryActivity extends Activitypublic MyMirrorGallery gallery;Overridepublic void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState);setContentView(R.layout.my_ga
