menu的创建及选择

Activity中实现如下两个方法，add(groupid,itemid,order,title)或者add(groupId, itemId, order, titleRes)

titleRes为资源id，可自定义菜单项的图标

item.getItemId()方法得到菜单项的id，case语句判断id分别处理

 1     @Override
 2     public boolean onCreateOptionsMenu(Menu menu) {
 3         // TODO Auto-generated method stub
 4         menu.add(0, 0, 0, "about");
 5         menu.add(0, 1, 1, "exit");
 6         return super.onCreateOptionsMenu(menu);
 7     }
 8 
 9     @Override
10     public boolean onOptionsItemSelected(MenuItem item) {
11         // TODO Auto-generated method stub
12         super.onOptionsItemSelected(item);
13         switch (item.getItemId()) {
14         case 0:
15             openOptionDialog();
16             break;
17         case 1:
18             exitOptionDialog();
19             break;
20         }
21         return true;
22     }
