Android中使用XML文件配置OptionMenu

1，配置布局文件

menu.xml:这里定义有哪些菜单，支持子菜单定义

<?xml version="1.0" encoding="utf-8"?>

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

<item android:id="@+id/close" android:title="Close"

android:orderInCategory="3" android:icon="@drawable/eject" />

<item android:id="@+id/no_icon" android:orderInCategory="2"

android:title="Sans Icon" />

<item android:id="@+id/disabled" android:orderInCategory="4"

android:enabled="false" android:title="Disabled" />

<group android:id="@+id/other_stuff" android:menuCategory="secondary"

android:visible="false">

<item android:id="@+id/later" android:orderInCategory="0"

android:title="2nd-To-Last" />

<item android:id="@+id/last" android:orderInCategory="1"

android:title="Last" />

</group>

<item android:id="@+id/submenu" android:orderInCategory="3"

android:title="A Submenu">

<menu>

<item android:id="@+id/non_ghost" android:title="Non-Ghost"

android:visible="true" android:alphabeticShortcut="n" />

<item android:id="@+id/ghost" android:title="A Ghost"

android:visible="false" android:alphabeticShortcut="g" />

</menu>

</item>

</menu>

main.xml:其实没有任何显示的内容

<?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"

>

</LinearLayout>

2、Java代码

package yyl.xmlMenu;

import android.app.Activity;

import android.os.Bundle;

import android.view.ContextMenu;

import android.view.ContextMenu.ContextMenuInfo;

import android.view.Menu;

import android.view.MenuInflater;

import android.view.View;

public class XmlMenuAcitvity extends Activity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

//将页面定义的menu配置到到activity中

new MenuInflater(getApplication())

.inflate(R.layout.menu, menu);

return super.onCreateOptionsMenu(menu);

}

}
