使用子菜單(SubMenu)的工作示例:

package com.AndroidMenu;

import android.app.Activity;

import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.SubMenu;
import android.widget.Toast;

public class AndroidMenuActivity extends Activity {
 
 final static int OPTION_ID_1 = 1;
 final static int OPTION_ID_2 = 2;
 final static int OPTION_ID_3 = 3;
 final static int OPTION_ID_4 = 4;
 final static int OPTION_ID_5 = 5;
 
 final static int OPTION_ID_6 = 6;
 final static int OPTION_ID_6_1 = 61;
 final static int OPTION_ID_6_2 = 62;
 final static int OPTION_ID_6_3 = 63;
 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // TODO Auto-generated method stub
  super.onCreateOptionsMenu(menu);
  
  //menu.add(Group, item id, order, title);
  menu.add(0, OPTION_ID_1, 0, "Option 1");
  menu.add(0, OPTION_ID_2, 1, "Option 2");
  menu.add(0, OPTION_ID_3, 2, "Option 3");
  menu.add(0, OPTION_ID_4, 3, "Option 4");
  menu.add(0, OPTION_ID_5, 4, "Option 5");
  
  SubMenu subMenu6 = menu.addSubMenu(0, OPTION_ID_5, 5, "SubMenu");
  subMenu6.add(0, OPTION_ID_6_1, 0, "SubMenu6.1");
  subMenu6.add(0, OPTION_ID_6_2, 0, "SubMenu6.2");
  subMenu6.add(0, OPTION_ID_6_3, 0, "SubMenu6.3");
  
  return true;
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
  // TODO Auto-generated method stub
  
  switch(item.getItemId()){
  case OPTION_ID_1:
   Toast.makeText(AndroidMenuActivity.this, 
     item.getTitle(), 
     Toast.LENGTH_LONG).show();
   break;
  case OPTION_ID_2:
   Toast.makeText(AndroidMenuActivity.this, 
     item.getTitle(), 
     Toast.LENGTH_LONG).show();
   break;
  case OPTION_ID_3:
   Toast.makeText(AndroidMenuActivity.this, 
     item.getTitle(), 
     Toast.LENGTH_LONG).show();
   break;
  case OPTION_ID_4:
   Toast.makeText(AndroidMenuActivity.this, 
     item.getTitle(), 
     Toast.LENGTH_LONG).show();
   break;
  case OPTION_ID_5:
   Toast.makeText(AndroidMenuActivity.this, 
     item.getTitle(), 
     Toast.LENGTH_LONG).show();
   break;
  default:
   Toast.makeText(AndroidMenuActivity.this, 
     item.getTitle(),
