Android学习第七天----menu2

添加menu的第二种方法，直接在java文件当中添加即可。

package com.example.menu_2;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.SubMenu;

public class MainActivity extends Activity
{
    private static final int SETTING_ABOUT = Menu.FIRST;
    private static final int SETTING_S = Menu.FIRST+1;
    private static final int SETTING_A = Menu.FIRST+2;
    private static final int SETTING_AB = Menu.FIRST+3;
    private static final int SETTING_ABO = Menu.FIRST+4;
    private static final int SETTING_ABOT = Menu.FIRST+5;
    private static final int SETTING_OUT = Menu.FIRST+6;
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu)
    {
        
        getMenuInflater().inflate(R.menu.activity_main, menu);
        
        menu.add(Menu.NONE, SETTING_AB, Menu.NONE, "AB");
        menu.add(Menu.NONE, SETTING_A, Menu.NONE, "A");
        menu.add(Menu.NONE, SETTING_ABO, Menu.NONE, "ABO");

        
        SubMenu sub = menu.addSubMenu(Menu.NONE, SETTING_ABOT, Menu.NONE, "abot");
        menu.add(Menu.NONE, SETTING_OUT, Menu.NONE, "out");
        menu.add(Menu.NONE, SETTING_ABOUT, Menu.NONE, "ABout");
        return true;
    }

}
