Question

这是我正在做的程序我在main.xml中创建了两个项目，即“关于我们”和“首选项”，我想在我的程序中使用但是当我尝试使用inflate方法访问main.xml时在MenuInflater中它无法找到我的资源。

package com.sagar.firstapp;

import android.R;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.MenuInflater;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class Menu extends ListActivity{

    String classes[]={"StartingPoint","TextPlay","Email","Camera","Data","example5"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter(Menu.this,android.R.layout.simple_list_item_1, classes));
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub
        super.onListItemClick(l, v, position, id);
        String cheese=classes[position];
        try {
            Class ourclass=Class.forName("com.sagar.firstapp."+cheese);
            Intent ourintent=new Intent(Menu.this,ourclass);
            startActivity(ourintent);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }

    }

    @Override
    public boolean onCreateOptionsMenu(android.view.Menu menu) {
        // TODO Auto-generated method stub
        super.onCreateOptionsMenu(menu);
        MenuInflater blowup=getMenuInflater();
        blowup.inflate(R.menu.main, menu);/*Can't find my main.xml   resource*/
        return true;
    }
}

这是我的main.xml代码

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item 
     android:title="About Us"   
     android:id="@+id/aboutus"
     android:numericShortcut="1"
     android:alphabeticShortcut="a"/>

    <item 
     android:title="Preferences"   
     android:id="@+id/preferences"
     />

R.java（生成的行）

public static final int aboutus=0x7f09001d;
public static final int preferences=0x7f09001e;

public static final class menu {
        public static final int main=0x7f080000;
    }

在res /菜单文件夹下创建main.xml

<强> main.xml中

<menu xmlns:androclass="http://schemas.android.com/apk/res/android" >  
    <item  android:id="@+id/item1"  
        android:title="About Us"/>  
    <item  android:id="@+id/item2"  
        android:title="Preferences"/>  

</menu>

以及inflate()

中的活动致电onCreateOptionsMenu(menu menu)

 @Override  
    public boolean onCreateOptionsMenu(Menu menu) {  
        // Inflate the menu; this adds items to the action bar if it is present.  
        getMenuInflater().inflate(R.menu.main, menu);//Menu Resource, Menu  
        return true;  
    }

如何通过inflate（）方法访问我的资源，即菜单？
