菜单是用户界面中最常见的元素之一，使用非常频繁，在Android中，菜单被分为如下三种，选项菜单（OptionsMenu）、上下文菜单（ContextMenu）和子菜单（SubMenu），今天这讲是OptionsMenu　

　4。其他按需要重载

package com.wjq.menu;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class DefaultMenu extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    public void onOptionsMenuClosed(Menu menu) {
        Toast.makeText(this, "选项菜单关闭了", Toast.LENGTH_LONG).show();
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {
        Toast.makeText(this,
                "选项菜单显示之前onPrepareOptionsMenu方法会被调用，你可以用此方法来根据打当时的情况调整菜单",
                Toast.LENGTH_LONG).show();
  // 如果返回false，此方法就把用户点击menu的动作给消费了，onCreateOptionsMenu方法将不会被调用
        return true;
    }
}

三、自定义样式

1.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>

　首先自定义菜单界面，我是GridView来包含菜单项，4列3行

2.item_menu.xml

<?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>

菜单项的现实样式，一个图标和一个文字。

3.定义

代码

private boolean isMore = false;// menu菜单翻页控制
    AlertDialog menuDialog;// menu菜单Dialog
    GridView menuGrid;
    View menuView;
    
    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

    
    /** 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" };

4.public boolean onMenuOpened(int featureId, Menu menu)

@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
    }

如果第一次打开则设置视图，否则直接显示menuDialog视图。

5.private SimpleAdapter getMenuAdapter(String[] menuNameArray,

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;
    }

为菜单添加菜单项。

6.public boolean onCreateOptionsMenu(Menu menu)

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        menu.add("menu");// 必须创建一项
        return super.onCreateOptionsMenu(menu);
    }

7.protected void onCreate(Bundle savedInstanceState)

@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        
        setContentView(R.layout.main);
        
        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;
            }
        });

        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;
                }
                
                
            }
        });
    }
