Android 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. */
	@Override
	public 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{

		@Override
		public void onClick(View v) {
			// TODO Auto-generated method stub
			if(v==btnCustomizeMenu){
				Intent it = new Intent();
				it.setClass(DefaultMenu.this, CustomizeMenu.class);
				startActivity(it);
			}
		}
		 
	 }
	@Override
	public 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;

	}

	@Override
	public 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;

	}

	@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;

	}
}
