基于Android平台的菜谱实现

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。如图2-7： 图2-73编码3.1镜像显示public class MyMirrorGalleryActivity extends Activitypublic MyMirrorGallery gallery;Overridepublic void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState);setContentView(R.layout.my_gallery); /Action Bar ActionBar actionBar = getActionBar(); actionBar.setDisplayHomeAsUpEnabled(true); actionBar.setDisplayShowHomeEnabled(true); actionBar.hide(); actionBar.show(); /-show it again- gallery=(MyMirrorGallery)findViewById(R.id.Mygallery);gallery.setAdapter(new MyAdapter(this); Override public boolean onCreateOptionsMenu(Menu menu) super.onCreateOptionsMenu(menu); CreateMenu(menu); return true; Override public boolean onOptionsItemSelected(MenuItem item) return MenuChoice(item); private void CreateMenu(Menu menu) MenuItem mnu1 = menu.add(0, 0, 0, 详情显示); mnu1.setIcon(R.drawable.ic_launcher); mnu1.setShowAsAction( MenuItem.SHOW_AS_ACTION_NEVER | MenuItem.SHOW_AS_ACTION_WITH_TEXT); MenuItem mnu2 = menu.add(0, 1, 1, 软件所有权); mnu2.setIcon(R.drawable.ic_launcher); mnu2.setShowAsAction( MenuItem.SHOW_AS_ACTION_NEVER | MenuItem.SHOW_AS_ACTION_WITH_TEXT); MenuItem mnu3 = menu.add(0, 2, 2, 使用说明); mnu3.setIcon(R.drawable.ic_launcher); mnu3.setShowAsAction( MenuItem.SHOW_AS_ACTION_NEVER | MenuItem.SHOW_AS_ACTION_WITH_TEXT); private boolean MenuChoice(MenuItem item) switch (item.getItemId() case android.R.id.home: Toast.makeText(this, You clicked on the Application icon, Toast.LENGTH_LONG).show(); Intent i = new Intent(this, MyMirrorGalleryActivity.class); i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(i); return true; case 0: Intent i2 = new Intent(this, MenuActivity.class); i2.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(i2); return true; case 1: Toast.makeText(this, 软件说明：, Toast.LENGTH_LONG).show(); new AlertDialog.Builder(MyMirrorGalleryActivity.this) .setTitle(软件说明：) .setMessage(软件著作：*n适用范围：所有爱好美食的人n ) .setPositiveButton(确定, null) .show(); return true; case 2: Toast.makeText(this, 使用说明, Toast.LENGTH_LONG).show(); new AlertDialog.Builder(MyMirrorGalleryActivity.this) .setTitle(使用说明：) .setMessage(使用方法：n 1.选择食物类型;n 2.查看食物n 3.选择心仪的菜品n ) .setPositiveButton(确定, null) .show(); return true; return false; 3.2添加菜品public class AddFoodActivity extends Activity protected void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState);setContentView(R.layout.addfood);Spinner();Button btn_save=(Button) findViewById(R.id.btn_save);btn_save.setOnClickListener(new OnClickListener() public void onClick(View v) / TODO Auto-generated method stubEditText editText1_foodname=(EditText) findViewById(R.id.editText1_foodname);/EditText spinner1=(EditText) findViewById(R.id.spinner1);Spinner spinnerGroup = (Spinner) findViewById(R.id.spinner1);EditText editText1_describe=(EditText) findViewById(R.id.editText1_describe);String foodname=editText1_foodname.getText().toString();/String editspinner1=spinner1.getText().toString();String classification = spinnerGroup.getSelectedItem().toString();String describe=editText1_describe.getText().toString();FoodMenu food=new FoodMenu(foodname, describe, classification);MenuService dbOpenHelper=new MenuService(AddFoodActivity.this);dbOpenHelper.add(food);/修改Intent i = new Intent(AddFoodActivity.this, MenuActivity.class); i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(i);finish(););public boolean onCreateOptionsMenu(Menu menu) / Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.add_food, menu);return true;public boolean onOptionsItemSelected(MenuItem item) / Handle action bar item clicks here.
