基于Android平台的菜谱实现1需求分析随着手机的广泛普及，无线技术的突飞猛进，移动生活、移动办公逐渐由概念转变为现实，对于传统的餐饮业也产生了潜移默化的影响。

目前，大多数餐厅仍然以传统的纸质菜单为主。

但是,这种点菜方式存在诸多弊端：从消费者角度来讲，菜谱不能及时更新，导致菜谱信息陈旧，点菜时经常出现某菜品已下架等情况。

用户需求：从餐厅老板来说，及时更新纸质的菜谱，无疑会增加餐厅的额外支出。

为了改善传统纸质菜谱的弊端，将菜谱应用于手机客户端，为消费者带来更为便利的客户体验。

而实时的菜品更新，不仅解决了纸质菜谱短时间内就出现脏、乱、差的问题，实现餐厅无纸化操作，而且潜在的提升了饭店的形象。

功能需求：用户可以进入菜单界面选择菜品分类，进入相应的分类内，查看该分类中的菜品信息，并对菜品的等级程度进行评价，查询某特定菜品，也可添加新菜品，删除菜品等。

2功能实现本APP基于自身的需求，同时对西北大学周围众多餐厅现状的合理分析，结合实际，设计并实现了一个基于移动手机平台的智能菜谱显示，该系统的设计基于Android智能操作系统，简单的SQLite数据库，实现了对菜品的增、删、查、改各个功能。

消费者可以添加要点的菜品，在餐后可以对菜品的口味及好感程度进行具体化的评价，这样是对餐厅工作人员的一个回馈，同时也可以为其他消费者就餐提供建议。

2.1主界面1、实现了对菜品的具体分类。

如图2-1图2-1单击所选择的菜品分类，出现菜品的镜像显示，为消费者提供更为直观的视觉效果，有助于消费者做出选择。

如图2-2图2-22、是进入菜品显示的入口，同时也显示了该软件的使用方法如图2-3：图2-32.2菜谱显示界面1、该类菜品中所有菜品的具体展示，菜品名称、菜品分类、菜品描述、菜品编号、以及菜品的星级评价，单选或多选菜品。

如图2-4：图2-42、搜索菜品菜谱显示界面会显示该分类下的所有菜品，当需要直接看到某单个菜品的具体消息时，可以通过搜索框，进行菜名的特定筛选。

如图2-5图2-53、对菜品进行添加4、删除菜品当菜品长时间被消费者冷落，或者有不想再推出的菜品时，进行及时的删除。

为消费者提供实时的消息。

如图2-6：图2-62.3菜品添加界面当有新的菜品推出时，进行及时的添加，为消费者提供更多选择。

软件对菜品的分类给与明确的选择，给用户提供便利。
