安卓菜单的实现，各种添加菜单的方法。

 1 @Override
 2     public boolean onCreateOptionsMenu(Menu menu) {
 3         super.onCreateOptionsMenu(menu);
 4 
 5         // 添加菜单
 6         menu.add("菜单选项1");
 7         /*
 8          * pram1:组号 pram2:唯一的ID号 pram3:排序号 pram4:标题
 9          */
10         menu.add(1, Menu.FIRST, Menu.FIRST, "菜单选项2");
11 
12         // 希望显示菜单就返回true
13         return true;
14     }

 1 @Override
 2     public boolean onCreateOptionsMenu(Menu menu) {
 3         super.onCreateOptionsMenu(menu);
 4 
 5         int group1 = 1;
 6         int group2 = 2;
 7         menu.add(group1, 1, 1, "item1");
 8         menu.add(group1, 2, 2, "item2");
 9         menu.add(group2, 3, 3, "item3");
10         menu.add(group2, 4, 4, "item4");
11 
12         // menu.removeGroup(group1);//删除一个组
13         // menu.setGroupVisible(group1, false);//设置可见性
14         // menu.setGroupEnabled(group2, false);//设置是否可点
15         // menu.setGroupCheckable(group2, true, t);//设置一组菜单的勾选情况
16         return true;
17     }

 1 @Override
 2     public boolean onOptionsItemSelected(MenuItem item) {
 3         // 响应每个菜单项(通过菜单项的ID)
 4         switch (item.getItemId()) {
 5         case 1:
 6             // do something here
 7             break;

19             return super.onOptionsItemSelected(item);
20         }
21          //返回true表示处理完菜单项的事件，不需要将该事件继续传播下去了
22         return true;
23     }

 1 //第一步：创建监听器类
 2 class MyMenuItemClickListener implements OnMenuItemClickListener {

 5         // do something here...
 6         return   true;    //finish handling
 7     }

 9 //第二步：为菜单项注册监听器
10 menuItem.setOnMenuItemClickListener(new MyMenuItemClickListener());
