准备菜单数据

/** 菜单图片 **/
	int[] menu_image_array = { R.drawable.menu_search,
			R.drawable.menu_filemanager, R.drawable.menu_downmanager,
			R.drawable.menu_fullscreen, R.drawable.menu_inputurl,
			R.drawable.menu_bookmark, R.drawable.menu_bookmark_sync_import,
			R.drawable.menu_sharepage, R.drawable.menu_quit,
			R.drawable.menu_nightmode, R.drawable.menu_refresh,
			R.drawable.menu_more };
	/** 菜单文字 **/
	String[] menu_name_array = { "搜索", "文件管理", "下载管理", "全屏", "网址", "书签",
			"加入书签", "分享页面", "退出", "夜间模式", "刷新", "更多" };
	/** 菜单图片2 **/
	int[] menu_image_array2 = { R.drawable.menu_auto_landscape,
			R.drawable.menu_penselectmodel, R.drawable.menu_page_attr,
			R.drawable.menu_novel_mode, R.drawable.menu_page_updown,
			R.drawable.menu_checkupdate, R.drawable.menu_checknet,
			R.drawable.menu_refreshtimer, R.drawable.menu_syssettings,
			R.drawable.menu_help, R.drawable.menu_about, R.drawable.menu_return };
	/** 菜单文字2 **/
	String[] menu_name_array2 = { "自动横屏", "笔选模式", "阅读模式", "浏览模式", "快捷翻页",
			"检查更新", "检查网络", "定时刷新", "设置", "帮助", "关于", "返回" };


在点击menu时显示自定义菜单AlertDialog

//如果是第一次打开则创建AlertDialog
	@Override
	public boolean onMenuOpened(int featureId, Menu menu) {
		if (menuDialog == null) {
			menuDialog = new AlertDialog.Builder(this).setView(menuView).show();
		} else {
			menuDialog.show();
		}
		return false;// 返回为true 则显示系统menu
	}

AlertDialog的View设置为menuView,menuView取自 gridview_menu.xml

当点击home键时取消Dialog

AlertDialog menuDialog;// menu菜单Dialog
	GridView menuGrid;
	View menuView;


menuView = View.inflate(this, R.layout.gridview_menu, null);
// 创建AlertDialog
menuDialog = new AlertDialog.Builder(this).create();
menuDialog.setView(menuView);
menuDialog.setOnKeyListener(new OnKeyListener() {
   public boolean onKey(DialogInterface dialog, int keyCode,
         KeyEvent event) {
      if (keyCode == KeyEvent.KEYCODE_MENU)// 监听按键
         dialog.dismiss();
      return false;
   }
});
gridview_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<GridView
         android:id="@+id/gridview"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:numColumns="4"
         android:verticalSpacing="10dip"
         android:horizontalSpacing="10dip"
         android:stretchMode="columnWidth"
         android:gravity="center"
         />
  
</LinearLayout>
取出GridView并设置Adapter
设置点击事件,点击更和返回多时更换Adapter,
 
设置翻页控制变量
private boolean isMore = false;// menu菜单翻页控制
设置选项id,从0-11 一共12个键
private final int ITEM_SEARCH = 0;// 搜索
	private final int ITEM_FILE_MANAGER = 1;// 文件管理
	private final int ITEM_DOWN_MANAGER = 2;// 下载管理
	private final int ITEM_FULLSCREEN = 3;// 全屏
	private final int ITEM_MORE = 11;// 菜单



menuGrid = (GridView) menuView.findViewById(R.id.gridview);
		menuGrid.setAdapter(getMenuAdapter(menu_name_array, menu_image_array));
		/** 监听menu选项 **/
		menuGrid.setOnItemClickListener(new OnItemClickListener() {
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				switch (arg2) {
				case ITEM_SEARCH:// 搜索
					break;
				case ITEM_FILE_MANAGER:// 文件管理
					break;
				case ITEM_DOWN_MANAGER:// 下载管理
					break;
				case ITEM_FULLSCREEN:// 全屏
					break;
				case ITEM_MORE:// 翻页
					if (isMore) {
						menuGrid.setAdapter(getMenuAdapter(menu_name_array2,
								menu_image_array2));
						isMore = false;
					} else {// 首页
						menuGrid.setAdapter(getMenuAdapter(menu_name_array,
								menu_image_array));
						isMore = true;
					}
					menuGrid.invalidate();// 更新menu
					menuGrid.setSelection(ITEM_MORE);
					break;
				}
				
				
			}
		});
获取设置GridView的Adapter Adapter绑定item_image.xml
//根据图片和文字创建Adapter
	private SimpleAdapter getMenuAdapter(String[] menuNameArray,
			int[] imageResourceArray) {
		ArrayList<HashMap<String, Object>> data = new ArrayList<HashMap<String, Object>>();
		for (int i = 0; i < menuNameArray.length; i++) {
			HashMap<String, Object> map = new HashMap<String, Object>();
			map.put("itemImage", imageResourceArray[i]);
			map.put("itemText", menuNameArray[i]);
			data.add(map);
		}
		SimpleAdapter simperAdapter = new SimpleAdapter(this, data,
				R.layout.item_menu, new String[] { "itemImage", "itemText" },
				new int[] { R.id.item_image, R.id.item_text });
		return simperAdapter;
	}
item_image.xml 相当于GridView中的每个选项
 
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:id="@+id/RelativeLayout_Item"
	android:layout_width="fill_parent" android:layout_height="wrap_content"
	android:paddingBottom="5dip">
	<ImageView android:id="@+id/item_image"
		android:layout_centerHorizontal="true" android:layout_width="wrap_content"
		android:layout_height="wrap_content"></ImageView>
	<TextView android:layout_below="@id/item_image" android:id="@+id/item_text"
		android:layout_centerHorizontal="true" android:layout_width="wrap_content"
		android:layout_height="wrap_content" android:text="选项"></TextView>
</RelativeLayout>
