Android(安卓)系统菜单与自定义菜单

Android 系统菜单与自定义菜单实现方法如下：
系统菜单显示DefaultMenu.java

package com.wxz.menu;import com.wxz.menu.R;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Button;import android.widget.TextView;import android.widget.Toast;public class DefaultMenu extends Activity {private Button btnCustomizeMenu;private TextView tvTip;/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);this.setTitle("Android 系统菜单");  btnCustomizeMenu = (Button)findViewById(R.id.btnCustomizeMenu);  btnCustomizeMenu.setOnClickListener(new ClickEvent());  tvTip = (TextView)findViewById(R.id.tvTip);  tvTip.setText("请按Menu键(F2)显示系统菜单");} class ClickEvent implements View.OnClickListener{@Overridepublic void onClick(View v) {// TODO Auto-generated method stubif(v==btnCustomizeMenu){Intent it = new Intent();it.setClass(DefaultMenu.this, CustomizeMenu.class);startActivity(it);}}  }@Overridepublic boolean onCreateOptionsMenu(Menu menu) {/* *  * add()方法的四个参数，依次是： *  * 1、组别，如果不分组的话就写Menu.NONE, *  * 2、Id，这个很重要，Android根据这个Id来确定不同的菜单 *  * 3、顺序，那个菜单现在在前面由这个参数的大小决定 *  * 4、文本，菜单的显示文本 */menu.add(Menu.NONE, Menu.FIRST + 1, 2, "删除").setIcon(android.R.drawable.ic_menu_delete);// setIcon()方法为菜单设置图标，这里使用的是系统自带的图标，以// android.R开头的资源是系统提供的，我们自己提供的资源是以R开头的menu.add(Menu.NONE, Menu.FIRST + 2, 3, "保存").setIcon(android.R.drawable.ic_menu_edit);menu.add(Menu.NONE, Menu.FIRST + 3, 4, "帮助").setIcon(android.R.drawable.ic_menu_help);menu.add(Menu.NONE, Menu.FIRST + 4, 1, "添加").setIcon(android.R.drawable.ic_menu_add);        //返回true则显示，返回false则不显示    return true;}@Overridepublic boolean onOptionsItemSelected(MenuItem item) {switch (item.getItemId()) {case Menu.FIRST + 1:Toast.makeText(this, "删除菜单被点击了", Toast.LENGTH_LONG).show();break;case Menu.FIRST + 2:Toast.makeText(this, "保存菜单被点击了", Toast.LENGTH_LONG).show();break;case Menu.FIRST + 3:Toast.makeText(this, "帮助菜单被点击了", Toast.LENGTH_LONG).show();break;case Menu.FIRST + 4:Toast.makeText(this, "添加菜单被点击了", Toast.LENGTH_LONG).show();break;   }        // 返回false则正常显示，返回true则被消费掉return false;}@Overridepublic void onOptionsMenuClosed(Menu menu) {Toast.makeText(this, "选项菜单关闭了", Toast.LENGTH_LONG).show();}@Overridepublic 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;}}

自定义菜单显示CustomizeMenu.java
